Ch World (match) (34)
This game - the 34'th - was the last in the match and secured Alekhine the title of World Champion.
and black holds the position.
Capablanca now gets a very difficult position.
The best was probably 21...Na4!? as suggested by Lasker
The tempting 30. Nxe4? fails because of
30... Qd6! 31. Qxc4 Qxe5 32. Re1 Nd6 33. Qc1! Qf6 34. Ne4 Nxe4 35. Rxe4 Rb8 36. Re2 Ra8 37. Ra2 Ra5 38. Qc7 Qa6 39. Qc3+ Kh7 40. Rd2 Qb6 41. Rd7 Qb1+ 42. Kh2 Qb8+ 43. g3 Rf5 44. Qd4! Qe8 45. Rd5 Rf3 46. h4 Qh8 47. Qb6! Qa1 48. Kg2 Rf6 49. Qd4 Qxd4 50. Rxd4
The position is won. Alekhine plays very carefully, but considering the importance of this game one can hardly blame him! The endgame has become a classic and can be found in many endgame books.
The rook behind the passed pawn!
Black cannot allow the white king to reach b5. In that case black's rook cannot stop the pawn.
Shows clearly why the rook is better placed behind the passed pawn. If the black rook moves the pawn advances. Pawn moves will not help, so black must allow the white king to advance.
There's no rush.
62. Kb3 gains nothing.
and black wins.
It is better to block the pawn with the king, but in this case it makes no difference to the final outcome.
The passive 65... Re7 loses after
This is ok, but there is a faster way:
Or 76... Kb7 and white wins like this:
At seven in the afternoon this sealed move was opened and Capablanca resigned immediately. Alekhine had won 6 games, lost 3 and was the new World Champion. Just before his death in 1946 Alekhine wrote: "How was it possible that he lost to me?...Even today I can't answer this question with certainty. In 1927 I wasn't convinced of my superiority. The main reason to his defeat may have been that he over estimated his own strength."1-0
