A Review of Educational Resources

Looking at my first post on this blog (Sunday, March 15th 2009), I noticed that I had a link to my Edublog's site that was still operational. My very first entry there was in September of 2007 and my last on December 24th 2008, almost exactly 9 years ago. I ceased using the Edublog site for blogging because it only offered 20Mb of storage. I'm not sure what it offers now. The blog is powered by WORDPRESS so it looks good.

I did have the Edublogs' app on my phone for a time but I've since deleted as it's really only useful if one has a class of students. Nonetheless, it's interesting to look back at past posts and read about my battles getting Ubuntu to work properly on my laptop. I'm reminded that I do have a WORDPRESS site at seanreeves.wordpress.com. It's titled Staying Healthy but I haven't made much use of it. My first entry was:
On the subject of students, I still have my free Moodle Cloud site active at http://seanreeves.moodlecloud.com but have made no use of it recently. I also have MAMP installed on my laptop but again haven't used it in quite a while. Having thought of MAMP however, I've taken the opportunity to download the latest version of the software: MAMP 4.2.1 (a 331Mb download from here although it's still not operational at the time of writing). May as well keep it up to date. I find it hard to let go of these relics of the past. There is of course Google Classroom as well, which I've only dabbled with briefly.

CHESS: A BUMBLED DRAW

I played a game at club level against Fritz Online and remembered that one needed a premium account to export files in PGN format. So I took a screenshot of the PGN displayed on Fritz Online and tried unsuccessfully to use OneNote and Google Docs to convert the image to text. Apparently it can be done but it defeated me. I turned to Google Keep and fortunately it was a very straightforward process. So I pasted the text into ChessX and things worked fine, so now I'm pasting the game into this blog. It's a game I should have won I'm sure but in the end was lucky not to lose, having overlooked a pin to my Queen from Fritz's Rook.
[Event "Casual Match"] [Site "Spring Hill"] [Date "2017.12.23"] [Round "4"] [White "Fritz: set to club player handicap"] [Black "Sean Reeves"] [Result "1/2-1/2"] [ECO "E15"] 1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Ba6 5.Qc2 Bb7 6.Bg2 c5 7.e3 Nc6 8.0-0 Rc8 9.a3 h6 10.Nbd2 Be7 11.b3 0-0 12.Bb2 cxd4 13.exd4 Qc7 14.Rac1 Rcd8 15.Rfe1 g5 16.Ne5 Nxe5 17.dxe5 Nh7 18.Be4 Bxe4 19.Nxe4 Qc6 20.Rcd1 b5 21.c5 Rb8 22.b4 Ra8 23.Nd6 Rab8 24.Rd2 Rbd8 25.Red1 Kg7 26.g4 Kg8 27.Rd3 Rb8 28.Rh3 Kg7 29.Ne4 Rfe8 30.Rd6 Bxd6 31.exd6+ f6 32.Nxf6 Nxf6 33.Bxf6+ Kxf6 34.Rxh6+ Ke5 35.Qc3+ Kd5 36.Qd3+ Ke5 37.f4+ gxf4 38.Rh5+ Kf6 39.g5+ Ke5 40.g6+ Kf6 41.Rh6 Rg8 42.g7+ Kxg7 43.Qg6+ Kf8 44.Rh8 Rxh8 45.Qf6+ Kg8 46.Qg6+ Kf8 47.Qf6+ Kg8 48.Qg6+ Kf8 1/2-1/2
It would seem that 39.g5+ was not the best move and that better would have been 39.Qh7 after which it's clearly curtains for Fritz. White has the luxury of not being able to be checked by the Black Queen, even though quite exposed. The g pawn is a shield against the Black Rook but this pawn was lost when I followed the line that I did.

CHESS: HOW TO EMBED A FULL CHESS GAME IN A BLOG

In this blog post I challenged myself to learn how to embed an entire game into a blog post, specifically this current blog post. I succeeded without too much difficulty. I've embedded a rather wild game from the Spassky versus Fischer World Championship Match in Reykjavik in 1972.

To get it to work (using the information on chessbase link), the PGN file is pasted into the HTML between DIV tags as follows:

Then some Javascript needs to be pasted in so that the ChessBase server can be accessed.


This is similar to how LaTeX gets rendered when I'm creating a mathematical post. While viewing in a browser in Android however, the LaTeX doesn't get rendered whereas with the embedded chess game, it does. However, in the Blogger app for Android, it is not displayed.

I guess what I need to investigate now is what control I have over how the game appears and what other chess websites provide this sort of service.
[Event "World Championship 28th"] [White "Spassky, Boris V"] [Black "Fischer, Robert James"] [Site "Reykjavik"] [Result "1–0"] [Date "1972.08.06"] [WhiteElo "2660"] [BlackElo "2785"] 1. e4 c5 2.

CHESS: The Budapest Gambit

I had been studying The Budapest Gambit via Bogdan Lalić's late 90's ebook described by the Amazon bookstore as "a relatively rare but sound attempt by Black to disrupt White's smooth development and this book provides up-to-date coverage of this sharp opening, ever-popular at club level". With the Black pieces against OS X's Chess program I played this opening but was surprised when White played 4.Qd4 which does not appear in any of the main lines covered in the book. However, there is a reference to this move in Games 73 and 74:


The book suggests that the best continuation for Black is 4...d6 which is what I played in my game. After which, play proceeds as 5.exd6 Bxd6 after which White plays 6.Nf3 in Game 74 and 6.Q4+ in Game 73. In my game, White played the former and play continued thus:


This led to the following position after Black's 19th move:


My position, I thought, was pretty solid but then White made a completely unexpected move, viz. 20.Nd5 cutting off my black-squared Bishop from the support of the Rooks.


I first tried 20...Bxf2+ but that doesn't work out so well. In the end I settled on 20...cxd5 which led to a drawn position although the program didn't concede a draw. Instead it just kept playing. Below is the situation after a seemingly interminable 169 moves, snapped from my perspective playing with the Black pieces (note HGFEDCBA file order from left to right):


I won't put down all the 169 moves but these moves (up to move 53 show where things are headed):


The chess program in OS X has a glitch whereby it crashes whenever I attempt to save the game in PGN format. It would be nice to learn how to embed a game with controls as they do on most of the online chess sites. I must investigate how to do this, otherwise my blog posts are rather limited.

CHESS: The Rules for Drawing

If the last 50 consecutive moves have been made by each player without the movement of any pawn and without the capture of any piece, the game can be declared a draw by either of the opponents. The other player's approval is not required, and the game ends immediately and is recorded as a draw for both players.
I was under the misapprehension that a draw could be claimed if 50 consecutive moves had been played without the capture of a piece. I'd forgotten or never knew about the requirement for no pawn moves to have occurred either. I had reason to recall the rule because I ended up playing a 3-D game on OS X that I eventually lost and in which Black carefully avoided a draw. It was an instructive game and it was surprising that I could hold out for as long as I did. Here are the moves:
1. d4 d5 2. Nf3 Nf6 3. e3 c5 4. c3 cxd4 5. cxd4 e6 6. Nc3 Bd6 7. Bd3 O‑O 8. O‑O Nc6 9. a3 Bd7 10. Bd2 Qb8 11. h3 a6 12. Rc1 Rc8 13. Qe2 Qa7 14. Na2 Rc7 15. b4 Rac8 16. Rc2 Ne4 17. Rfc1 b5 18. Be1 e5 19. dxe5 Nxe5 20. Nxe5 Bxe5 21. Rxc7 Rxc7 22. Rxc7 Qxc7 23. f3 Bh2+ 24. Kf1 Ng3+ 25. Bxg3 Bxg3 26. Qc2 Qxc2 27. Bxc2 Be5 28. e4 dxe4 29. Bxe4 Be6 30. Nc1 Bc4+ 31. Kf2 Bd4+ 32. Kg3 Bb2 33. Nd3 Bxd3 34. Bxd3 Bxa3 35. Be4 Bxb4 36. Bc6 Bd6+ 37. Kf2 b4 38. Ke2 b3 39. Kd2 Bb4+ 40. Kc1 Bc3 41. Bb7 a5 42. Bc6 Kf8 43. Ba4 b2+ 44. Kb1 f5 45. Bc2 Bd4 46. Ka2 g6 47. Kb3 Ke7 48. Kc4 Be5 49. Bb1 Ke6 50. Kc5 h5 51. Kc4 h4 52. Kd3 a4 53. Ke3 g5 54. Kd3 a3 55. Ke3 Bd6 56. Kd4 Kf6 57. Ke3 Ke5 58. Ba2 Bc5+ 59. Kd3 Kf4 60. Ke2 Kg3 61. Kf1 Bd4 62. Bb1 Kf4 63. Ke2 Bb6 64. Ba2 Bg1 65. Bb1 Bb6 66. Ba2 Bd4 67. Bb1 Kg3 68. Kf1 Be3 69. Ba2 Bd2 70. Bb1 Kf4 71. Ke2 Bb4 72. Ba2 Bd6 73. Bb1 Kg3 74. Kf1 Kf4 75. Ke2 Kg3 76. Kf1 Bc5 77. Ba2 Bb6 78. Bb1 Bd4 79. Ba2 Kf4 80. Ke2 Bb6 81. Bb1 Kg3 82. Kf1 Kh2 83. Ba2 Bd4 84. Bb1 Bc3 85. Ba2 Kg3 86. Bb1 Be5 87. Ba2 Bc3 88. Bb1 Be5 89. Ba2 Kf4 90. Ke2 Bc7 91. Bb1 Kg3 92. Kf1 Bb6 93. Ba2 Bf2 94. Bb1 Bd4 95. Ba2 Bc5 96. Bb1 Bb6 97. Ba2 Ba5 98. Bb1 Bc3 99. Ba2 Bd2 100. Bb1 Kf4 101. Ke2 Bb4 102. Ba2 Kg3 103. Kf1 Bc5 104. Bb1 f4 105. Ba2 Bb6 106. Bb1 Bc5 107. Ba2 Be3 108. Bb1 Bf2 109. Ba2 Be3 110. Bb1 Bf2 111. Ba2 Bb6 112. Bb1 Kh2 113. Ba2 Bd4 114. Bb1 Kg3 115. Ba2 g4 116. hxg4 h3 117. gxh3 Kxf3 118. g5 Ke3 119. h4 Kd2 120. h5 Kc2 121. g6 Bg7 122. Kf2 b1=Q 
I'll show the position I reached before it all went wrong for me. Black has just played 25...Bxg3 and I mistakenly decided to exchange Queens, after which the White pawn on a3 cannot be defended.


White has just played 34.Bxd3 and Black is now ready to play 34...Bxa3 and there's nothing White can do about it. Things look grim for White.


It would seem that two connected Black pawns on the queenside would be unstoppable if the White King is not present but such is not the case because the White Bishop is quite up to the task of holding off the Black pawns all by itself. However, White must keep the Black King from penetrating to the queenside. Because White can move the Bishop from b1 to a2 and back again, the White King cannot be forced to yield ground to the Black King. On move 53, Black played 53...a3 and Black did not move another pawn until 50 moves later:


Now Black on move 104 is well aware that another King or Bishop move would result in a draw because 50 moves would have passed since the last capture or pawn move. To avoid this, Black plays 104...f4, moving the pawn on f5 to f4.


After Black's 115th move, 115...g4, things fell apart quickly for White. I don't think there are viable drawing options for White but I'm not completely sure.

VOCABULARY: words ending in OSIS

Continuing with my pre-sleep activities, I'd been thinking about words ending in OSIS but could remember only a frustrating few such as psychosis, neurosis, mitosis, meiosis and kurtosis. I knew there must be many more. A search of THE FREE DICTIONARY led to the following:
  • A: atherosclerosis (a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries); ankylosis (abnormal stiffening and immobility of a joint due to fusion of the bones); asbestosis (a chronic inflammatory and scarring disease affecting the tissue of the lungs. People with the condition may experience severe shortness of breath and are at an increased risk for certain cancers, including lung cancer and, less commonly, mesothelioma); apotheosis.
  • B: brucellosis (a bacterial infection that affects thousands of people worldwide. Avoiding unpasteurised dairy products and taking precautions when working with animals or in a laboratory can help prevent brucellosis; symptoms may include joint and muscle pain, fever, weight loss and fatigue; some people develop stomach pain and cough; treatment includes antibiotics; relapses are common).
  • C: cyanosis (the bluish or purplish discolouration of the skin or mucous membranes due to the tissues near the skin surface having low oxygen saturation); cirrhosis (a condition in which the liver does not function properly due to long-term damage. This damage is characterised by the replacement of normal liver tissue by scar tissue; cirrhosis is most commonly caused by alcohol, hepatitis B, hepatitis C, and non-alcoholic fatty liver disease).
  • D: diagnosis; dermatosis (a broad term that refers to any disease of the skin, especially one that is not accompanied by inflammation e.g. dermatosis papulosa nigra (DPNs) are very common benign brown warty papules that appear in African Americans and other patients with dark skin phototypes; DPNs usually affect the cheeks, neck, and upper chest); diverticulosis.
  • E: endometriosis (a condition whereby the tissue from the inside of the womb is growing outside of it)
  • F: fibrosis (the formation of excess fibrous connective tissue in an organ or tissue in a reparative or reactive process. This can be a reactive, benign, or pathological state. In response to injury, this is called scarring, and if fibrosis arises from a single cell line, this is called a fibroma); fluorosis (dental fluorosis, also termed mottled enamel, is an extremely common disorder, characterised by hypomineralisation of tooth enamel caused by ingestion of excessive fluoride during enamel formation).
  • G: gnosis
  • H: halitosis; hypnosis
  • I: immunodiagnosis
  • J: none known
  • K: keratosis (solar keratosis or actinic keratosis, also commonly known as sunspots, are rough, red, scaly, or crusty spots on the skin that are caused by excessive exposure to Ultraviolet Radiation (UVR) from the sun. They are more common on sun-exposed areas, such as the face, nose, ears, chest, forearms, and back of the hands); kurtosis (the sharpness of the peak of a frequency-distribution curve).

CHESS: Holding On


This is the position that I reached after White's 41st move against Fritz set to Master Level. Here are the moves:


I'd managed to maintain material equality but I'd been in defensive mode for most of the game, and I still was. I was certainly on the back foot. My three pieces were on the back rank and there were various threats looming. I decided to take a break from the game and analyse the situation before proceeding. Fritz's analysis showed that the best way forward for Black was to play 41...exf4, although White still maintains the advantage. The suggested continuation was:


This sequence of moves leads to the following position (constructed using ChessX):


The frustration for Black is that he can't play (in the first position) Nc6 to drive away the White Rook because the b pawn is then lost. In the continuation described, Black does play Nc6 but at a later date. In any case, the key move for Black to regain some sort of offensive does seem to lie with 41...exf4.

CHESS: More Master Mauling


Here is the position I found myself in after 10.Bb2. I decided to castle and things fell apart quickly after White's devastating 11.Na4. Black's seemingly secure position was an illusion as the Knight move demonstrated. After the Knight move:

  • The Knight attacks Black's c5 pawn
  • The Knight threatens to settle on Black's b6 square
  • White's Black-squared Bishop threatens to take Black's Knight on c6 and expose Black's King
Black's c5 pawn is protected only by the Bishop so it cannot move to c7 to guard the b6 square. It is the Queen must move to either e8 or c7 to guard the b6 square. As it was, I moved the Queen to c7 and the White Bishop captured the Black Knight on f6. Here are the moves as they were played out:


What the Fritz analysis suggests as the best move for Black is 10...Nb4 with the following possible follow-up that doesn't quite achieve equality for Black but come closer to it than my bumbling attempt:


Even after castling and White's Knight move, it would have been better to play 10...Qe7 in order to recapture with the Queen, thus preventing the breakup of the pawn defence in front of the King and bringing the Queen to defence of the Kingside. Letting the White Knight settle on b6, if it chooses to, is not the end of the world. However, after 10...Qc7 and 11.Bxf6, it is the end of Black's world.

To me, White's position didn't look good. The white-square Bishop was sitting in front of the d pawn, preventing its advance. In fact, it was well-positioned and bearing down on Black's h pawn. The White Knight on c3 had been place there early, preventing the c pawn from advancing to c4 as it normally does in this sort of opening. As it turned out, the Knight's move to a4 later in the game proved my undoing.

VOCABULARY: words ending in EX

I often play a game as I'm trying to go to sleep in which I try to rhyme words ending in various combinations of letters. For two nights in a row, I was trying to finds words ending in ex and managed to find quite a few. However, I realised that there were plenty more that I was missing so today I determined to discover some more. Here are some of the more common words arranged alphabetically:
A: apex, annex
B: biconvex, biflex (meaning bent in two places) 
C: circumflex, codex, convex, cortex, complex, cybersex 
D: desex, duplex, diplex (pertaining to the simultaneous operation of two radio transmitters or to the simultaneous reception and transmission of radio signals over a single antenna through the use of two frequencies. 
E: the ending itself (ex) seems to be the only known word 
F: flex, fourplex (four family apartment house) 
G: googolplex (a number that is equal to 1 followed by a googol of zeros and expressed as 10^10^100 where a googol is a number that is equal to 1 followed by 100 zeros and expressed as 10^100). 
H: hex, haruspex (in ancient Rome, one of a class of minor priests who practiced divination, especially from the entrails of animals killed in sacrifice). 
I: ibex (any of several wild goats of the genus Capra, inhabiting mountainous regions of Eurasia and North Africa, having long, recurved horns), index, intersex (an individual having reproductive organs or external sexual characteristics of both male and female). 
J: no known words 
K: Kleenex (a brand name for a soft, disposable paper tissue, used especially as a handkerchief). 
L: lex (Latin for law), latex (a milky liquid in certain plants, as milkweeds, euphorbias, poppies, or the plants yielding India rubber, that coagulates on exposure to air). 
M: megaplex, multiplex 
N: neocortex 
O: octuplex (presumably an eight family apartment house) 
P: pyrex, perspex, perplex, pontifex (a member of the Pontifical College, which was presided over by a chief priest (Pontifex Maximus)) 
Q: quadplex 
R: rex, retroflex (bent backward) 
S: sex, spandex (a synthetic fibre composed of a long-chain polymer, used chiefly in the manufacture of garments to add elasticity), simplex, subcortex
T: triplex (threefold; triple).  
U: no known words 
V: vertex, vortex, vex
W: no known words 
X:  no known words 
Y: no known words 
Z: no known words 

It's always good to work some of these words into a sentence. For example, I'll vex my ex with a hex.

CHESS: Another Misstep


This is the position that was reached after 14 moves against Fritz set to Master Level. I have the White pieces and a solid enough position. However, I unwisely chose 15. Na4 and things quickly fell apart. I assumed that the Black Queen, once attacked, would retreat to c7 where I could attack it with my Bishop after Bg3. Black however, retreated to a7 and this was very different. Suddenly, I was a faced with the threat of a pawn fork from b5 and needed to return my Knight to the square it had just come from. Here are the moves with a brief analysis of the best continuation for White (15. Rfe1):


I certainly considered 15. Rfe1 when deliberating on my moves and it's a sensible move but unfortunately I decided on the Knight move, not realising the danger from the pawn fork. The bishop on h4 is also only defended by the Knight and is more secure on g3. It's vulnerable position on h4 ultimately led to its loss with 25. ... Bxh4 after which there was little point in continuing.

The lesson to be learned here to be always check for basic traps like pawn and Knight forks. The danger in my case was glaringly obvious. Sometimes it's less obvious. Here is an instructional configuration that involves the setting up of a pawn fork:


It's taken from http://www.chesstactics.org/, a site that boasts 20 chapters, about 200 topics within them, and over 1,000 positions discussed.

CHESS: Strategic Blunders


Above is the position after 14 moves of a Queen's Pawn opening. I have the White pieces and Black has just played Qb7. All my pieces are developed and I have a reasonable position in my opinion. I need to develop a strategic plan and the one I foolishly embarked upon involved moving my pawns to a3 and b4 to frustrate a c5 pawn move by Black. As it turned out, Black moved the pawn on b6 to b7 and this did not work in my favour. I'd buried my Bishop and, after I placed the Knight on c5 and Black placed the Knight on c4, my doubled Rooks were useless. Furthermore, the placement of my Knight was far less effective than Black's Knight placement. Black could exchange Bishop for Knight if I Knight became too powerful whereas White didn't have that option. White's buried Bishop was black-squared and Black's Knight was unmovable on its White square. From c4, the Knight bore down on e3 already under pressure from Black's Rook on the half-open file. Worst of all, the King side was completely undefended. Black is able to move his Rook up and across to the Kingside while the Queen and Bishop bear down as well. White's Queen cannot help in the defence.

My strategic plan was a sure loser against any competent player. A far better plan might have been to move the Knight on c3 across to the Kingside and keep bearing down on the half open c file with the two Rooks. This is not without it's problems too however, and so it's interesting to set the computer program (Stockfish) to analysis mode and see what strategy it comes up with. What it comes up with is interesting:


This approach is quite different and quite effective in maintaining the initiative for White. The above sequence of moves leads to the position shown below:

CHESS: Ding Lirin - China's highest ranked player ever

Ding Lirin has a peak rating of 2783. It's the highest rating any Chinese player has ever attained. There is an article in ChessBase from the 30th September 2017 about him after his runner-up performance at the World Cup which was won by Aronian. He was born on October 24th 1992 in Wenzhou in Zhejiang Province.


I came across an interesting game of his that was being discussed on a YouTube channel called ChessNetwork. Here is the video creator's introductory comments to the game:
Chess Masterpiece, Immortal Chess Game & Game of the Century are a few of the phrases that come to my mind after observing this magical game from Round 18 of the 2017 Chinese Chess League, played on November 4th. Grandmaster Bai Jinshi played as white against Ding Liren. The opening, a Nimzo-Indian Defense, three knights variation, saw Ding Liren ultimately play the part of some wizard of the game. Many elements of this game reminded me of 13-year-old Bobby Fischer's game against Donald Byrne from 1956, pegged "The Game of the Century". Might this game find its way onto the "Greatest Chess Games of All-Time" list?
Here are the moves:

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3 O-O 5. Bg5 c5 6. e3 cxd4 7. Qxd4 Nc6 8. Qd3 h6 9. Bh4 d5 10. Rd1 g5 11. Bg3 Ne4 12. Nd2 Nc5 13. Qc2 d4 14. Nf3 e5 15. Nxe5 dxc3 16. Rxd8 cxb2+ 17. Ke2 Rxd8 18. Qxb2 Na4 19. Qc2 Nc3+ 20. Kf3 Rd4 21. h3 h5 22. Bh2 g4+ 23. Kg3 Rd2 24. Qb3 Ne4+ 25. Kh4 Be7+ 26. Kxh5 Kg7 27. Bf4 Bf5 28. Bh6+ Kh7 29. Qxb7 Rxf2 30. Bg5 Rh8 31. Nxf7 Bg6+ 32. Kxg4 Ne5+

CHESS: Nodirbek Abdusattorov - 2nd Youngest Chess Grandmaster in History

Here is a game played early in 2017 before this latest prodigy, Nodirbek Abdusattorov from Uzbekistan, became a grandmaster at the age of 13 years, 1 month and 11 days.



In this game, Nodirbek is Black and plays the Nimzo-Indian defence against an Indian grandmaster, Nodirbek Abdusattorov, whom he defeats in a mere 19 moves. The game runs thus:

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 d5 5. cxd5 exd5 6. Bg5 h6 7. Bh4 O-O 8. e3 Be6 9. a3 Be7 10. Bd3 c5 11. dxc5 d4
12. exd4 Nc6 13. Nge2 Nxd4 14. Nxd4 Qxd4 15. Ne4 Nxe4
16. Bxe7 Bb3 17. Qe2 Nxf2 18. Qxf2 Qxd3 19. Qh4 Bc4

The master stroke comes when Black plays 16. ... Bb3 after which White is finished. Below is the position of the board before Black plays this move. After Black captured the Knight on e4 on his previous move, White captures the Bishop on e7, clearly not expecting what then happened.


As of October 2017, Nodirbek Abdusattorov has an ELO rating of 2498. Lailith Babu on the other hand has a current ranking of 2525 and achieved his highest ranking of 2594 in April of 2014. Here is a list of the top twenty players of all time, taken from Chess-DB. Note how Bobby Fisher still ranks in 18th position with an ELO rating of 2785, achieved in April of 1972 (when I turned 23).

Chess Diagrams

In the last few months, my interest in Chess has been rekindled in large part due to http://en.chessbase.com/ and the associated online Fritz Chess Program. However, only premium users of ChessBase can make use of the feature that allows the setting up of positions, important when following through an analysis provided in a chess book. For example, I have a book called 101 Chess Endgame Tips by Steve Giddins. Here is a typical position in which White must try to draw the game and not lose it.


I could not see how to set up the position in either the chess program that comes with macOS or Stockfish that I had downloaded. So I downloaded a program called ChessX, an open source program that I found at sourceforge and found that I was able to set the position easily and play it through as outlined in the book. This is a very useful feature. 

The position above leads with proper play to White having the opposition against the Black King and therefore securing a draw. The proper play is: 

1. Kg3!! Kc2 2. Kf2! d2 3. Kf1! Kd1 4. Kf2 Kd2 5. Kf1 Kd3 6. Ke1 Kc4 7. Kd2 Kb5 8. Kc3 Kxb6 9. Kb4 and White has the opposition and draws. Ultimately, the position will end up as shown below where White must be careful to retreat to b1 where the opposition can be maintained whether Black chooses to move the King to a3 or b3.
