|Aug-08-04|| ||offramp: From 40...Rc1+ to 56...Rc1+ must be one of the weirdest episodes of play in Grandmaster chess.
It's like Asteroids where you don't blow up the last rock and keep waiting for the 1000-point spaceships. |

|Aug-18-05|| ||LIFE Master AJ: An interesting chess game ... apprently the ending is one that has stirred some disagreement among the experts.|
|Aug-18-05|| ||LIFE Master AJ: 65...Bf7+? was an error. Several endgame experts have analyzed this ending in books and magazines ... and even come to opposite conclusions! |
Correct was: 65...Bb1! Now one 'expert' says the best practical chances for Black lie in the line 66.Bd3!? Ba2+!; 67.Kc5. Now Averbakh only gives 67...Kf4!?; 68.Kd4, Kg3; as winning for Black. Cheron discovered that Black probably draws with 68.Kd6! Probably best us 67...f5!; when IM Mark Dvoretsky gives a very long analysis ... and concludes that Black should win. (See Chapter Six, page # 111 of D's "Endgame Manual," which was published in 2003.)

How does Black then win?

< If White had played 75.Bb5 How does Black then win?>
Good point, it is a Nalimov tablebase draw after 75. Bb5! Kxg2 76. Kf4, and also after, say, 75. Bb5 Bc8 76. Bc6 Ba6 77. Bd5 Bf1 78. Bc6 Bxg2 79. Bd7, etc. I was not able to find any win.
|Mar-16-06|| ||waddayaplay: Pachman gives 75.Bb5 as a draw.
He also notes that 72.fxg! fxg 73.Ke3! would draw because if black takes the h-pawn, white exchanges bishops and the lone h-pawn can't win
|Jul-27-08|| ||4tmac: Starting with <offramp> diagram after WHITES 75. B-b5! and continuing with <beatgiant> 75. ... KxP 76. K-f4!! gains a tempo by attacking the bishop & draws vs. other lines. Say black plays 76. ... B-c8 (black must stay on this diagonal or white plays B-d7) |

White draws by 77. B-c6+! K-f2 78. B-b7!! B-e6(say) 79. B-d5!! BxB 80. K-g4!

Tablebase draw after any bishop move except Be2.
|Dec-26-14|| ||Sargon: Isn't this a draw?|
|Sep-01-16|| ||SimplicityRichard: No it is not a draw. Black in the resulting position wins outright. |
However, prior to this final position, White had opportunities for a draw. As noted by <Life Master AJ> 65...Bf7+ was an error on Black's part and could have led to a draw. However, <Life Master AJ> relying on analysis suggests that correct was 65...Bf1?! Actually in my analysis with Stockfish 7, correct is 65...Bf5! Black has a won game. 65... Bf1 also leads to a drawn game with correct play. And <offramp> is correct in that White had another opportunity for a draw with 75.Bb5! But White missed this opportunity. The trick is for White to position his Bishop cleverly on the diagonal where the black pawn will be traversing. But Marshall was well aware of this in the end and prevented this with 76...Bd7! (0-1).
|Sep-01-16|| ||SimplicityRichard: <Boomie> is also quite right. After 74...Bxg4, any Bishop move by White apart from Be2 leads to a draw.#|
|Sep-01-16|| ||Monkeyboy56: Did anyone notice that Marshall had a winning play at move 17? When Teichmann opened the a1-h8 diagonal with 17. d5, Marshall simply must check with 17...Bf5+. This leads to mate. If the bishop interposes on d3, then BxB+. QxB leaves the second rank unprotected, so 20...Qb2++! Teichmann can hang on a few more moves by interposing the Queen on c2 when the king gets marched up to d3 and then back to b1 for mate by this sequence of moves:|
17. d5 Bf5+
18. Qc2 Bxc2+
19. Kxc2 Qb2+
20. Kd3 Qd4+
21. Kc2 Qc3+
22. Kb1 Qb2++
|Sep-01-16|| ||Monkeyboy56: Of course Teichmann can avoid immediate loss by interposing both the bishop and queen creating an escape square on e2, but then Marshall will have simply won the queen and should win easily.|
|Sep-02-16|| ||Monkeyboy56: A friend pointed out to me that if the queen interposes on c2, then its an immediate mate by 18...Qb2 as the white queen is pinned. So no need for an elaborate king march!|
|Oct-14-16|| ||Pawn and Two: <Monkeyboy56> Our game score appears to be incorrect. I believe Black played 15...Qa6, not 15...Qa3. I checked the databases for chess tempo and 365 chess, and they both show the move 15...Qa6. Also, the books; "Marshall's Best Games of Chess" by Frank Marshall; "Frank Marshall United States Chess Champion" by Andy Soltis; and the San Sebastian tournament book by Mieses & Lewitt, all show Black played 15...Qa6, not 15...Qa3.|
I will ask chessgames.com to correct our game score.
