It was a blunder, objectively speaking, that put a black pawn on g3. Black staked the whole game on setting up a checkmate that White could have stopped fairly easily. But White greedily grabbed first a pawn that was en prise, then grabbed with his own cleric the bishop that had taken the knight on f3. Now it's Black's move and checkmate in seven.

In this position against Veselin Topalov, Wijk aan Zee 2003, Vladimir Kramnik played 50.f4. He indicated in his annotations to the game in Informant 86 that the move was a mistake.
What move was better?

Last December I passed along an email Informant sent out announcing their one hundredth issue. Shortly after publishing Informant 100, Šahovski Informator released The Best of the Best 1000—the ten best games from each of the first one hundred volumes, published with their original annotations. Joel Benjamin wrote a review of this book for his New York Times Chess Blog. With the prize money I earned from playing in the Spokane City Championship I was able to shell out the $60 for a paperback book and have been poring over some of the games.
Black to move
What happens if Black captures the knight on h7?
The position above did not occur in a game, but in the annotations by Rudolf Marić to Bobby Fischer’s win over Leonid Stein in the 1967 Interzonal in
[T]his is the first instance in the history of chess, when a player has withdrawn from a tournament when he was leading.”
PaulKeres, Chess Life 1968
Among the accommodations for the guests at the Sousse-Palace Hotel, where the Interzonal was held, were use of a “camel, donkey, speed boat, and small yacht” (Brady, Bobby Fischer: Profile of a Prodigy, 134). Frank Brady observes that several problems emerged due to inadequate event organization, including poor lighting, intrusions of a photographer from the Soviet Embassy of Tunisia, and unfair scheduling. Fischer had been granted a day off to observe the Sabbath, postponing his eighth round game with Victor Korchnoi. According to Brady, his ninth round game with Efim Geller unnecessarily also had been postponed, resulting in six consecutive days without a break. When Fischer sought to remedy this error, he was refused without being offered an explanation.
Fischer withdrew from the tournament and left for
While this issue was pending, the Soviet players threatened to withdraw en masse if Fischer was permitted to play his game against Gipslis. The committee caved to this pressure and ruled against Fischer, who then withdrew for the second and final time. Fischer then was forfeited against Vlastimil Hort. Still, Fischer “did want to play” (Brady, 138) and efforts were made to bring him back. Fischer’s next scheduled game was Saturday, 4 November 1967, against Bent Larsen. From his hotel in
I request to re-enter the 1967 Interzonal Tournament without prejudice to my claim that the forfeited games were decided illegally. I acknowledge that I have been declared forfeit against Gipslis and Hort; if the forfeits are ruled legal and were decided upon according to the rules of FIDE, I shall accept them. I request to play with Mr. Larsen tonight as soon as I can arrive in
, I presume between 9-9:30 P.M. Sousse
As quoted in Brady, 138.
This message arrived to the committee at 7:25 p.m., but Fischer’s clock had been started twenty-five minutes earlier. Fischer had no way to get to the tournament by 8:00 p.m., was forfeited from the game, and per FIDE rules, the event. His road to the World Championship became longer. Although Fischer scored 8 ½ in the ten games he played, he was out of the event before the mid-point and does not appear in the crosstables. Bent Larsen won the event.
Beating Leonid Stein
Garry Kasparov writes in My Great Predecessors, Part IV that after losing to Leonid Stein in a casual game at the 1966 Olympiad in
Kasparov’s annotations to the game run seven pages in My Great Predecessors. He references comments on the game by Hans Kmoch,

White to move
The problems in this text are organized by theme, so the solver immediately knows that a discovered attack figures into the solution. In this position, the only conceivable discovery is against the queen, so the bishop must be able to move with check. Thus, 1.Rxe6+! If 1...Bxe6, then 2.Bb5+ wins the queen for a bishop and rook, and Black's pawn structure is compromised. If 1...fxe6, then Bg6+. However, the king can move. To Reinfeld's credit, he gives the lines just mentioned and offers, "Black must move his king, remaining with a decidedly inferior game" (213).
The next problem in the text is more typical of the sort of suboptimal moves that pepper the solutions.
White to move
There is a discovery after Reinfeld's line: 1.Be7 Re8 2.Bb4 threatening both checkmate and the queen. But Black has other options. When I played this position against Hiarcs 10 a few months ago, the engine replied to 1.Be7 with Bxf2+. After 2.Kxf2 Re8 3.Bb4 Qb6+ saves the queen at the cost of a bishop. White still has a winning advantage, but the position is less one-sided than in Reinfeld's solution. Against the engine, I was able to achieve only a draw.
This morning I played the position again, but against a newer version of Hiarcs. Hiarcs 12 played 1...f5. That game continued 2.Ra4 Bxf2+ (still the bishop sacrifice) 3.Kxf2 Qb6+ 4.Kf1 Rf7 and this time I went on to win, showing improvement on may part.
