Our game is from Moscow 1936, a major double round-robin event won by Capablanca ahead of (then-) future world champion Mikhail Botvinnik and a number of other stars including Salo Flohr, former world champion Emanuel Lasker and the still-living Andor Lilienthal. Another participant was the strong Soviet master Ilya Kan, best known today as the founding father of the eponymous variation of the Sicilian Defense (1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6). While not in Capablanca's class, Kan was a respectable player in his own right, and managed to defeat the third-placed Flohr 1.5-.5 in the event and split a pair of games with Lasker. He also drew his first game with Capablanca - with Black, no less - and so with White the second time around it would seem he had reasonable chances to split their match.
Nothing about the opening suggested he'd have any difficulties in this regard. The players traded pieces as if they had prearranged a draw and wanted to make it look good for the audience. Yet despite reaching a double rook ending by move 23, the game was not yet drawn. While best play would surely result in a drawn outcome, Capablanca possessed a number of very small advantages. The difficulty for Kan was twofold: first, he was probably psychologically unprepared to fight for a draw, and may have just hoped it would fall into his lap with "normal", "good" moves. Second, there wasn't any way for him to force a draw. Capablanca could do this and that, improving his position on one side of the board, then the other side, and Kan needed to react - sometimes prophylactically, but sometimes with activity of his own. In short, Capablanca's position still had play, and Kan still had enough rope to hang himself.
The game is a model in several respects. "Capa" illustrates how to utilize a small advantage from both the practical and the psychological point of view. Conversely, we can learn from Kan's errors how to better prepare ourselves for a long defense. And concretely, there are various techniques Capablanca uses that we can adopt: play on both wings, using the minority attack in the endgame, the proper timing of pawn breaks, combining horizontal and vertical attacking ideas with rooks, and more. It's a beautiful game by one of chess's all-time greats, and you can watch it, live and for free, on ChessBase's Playchess.com server tomorrow (Wednesday) night at 9 p.m. ET.
