The Triumph of Quality
I think it was R.N. Coles who suggested that we think of chess along four dimensions: material, time, space, and position. Players typically understand them in that order, with position (or what others term the "quality" of your pieces, pawns, and king safety) the hardest to master, just as it was historically the last to emerge. The following game is a great illustration of how an advantage in piece quality (including scope and piece safety) can lead to victory.
Apsenieks - Geza Maroczy [D64]
Folkestone Olympiad (Men)/Folkestone (14.1) 1933
A slight inaccuracy which gives Black a tempo for development. Maroczy notes that superior is 7. Rc1 which practically forces Black to defend the pawn by 7... c6 when White is better after 8. cxd5 (8. Qc2) 8... exd5 9. Bd3.
"Black has won an important tempo, not having to move this pawn twice" notes Maroczy.
Apsenieks appea rs to be seeking an imbalance in order to prevent the position from slipping into symmetrical equality. But the two Bishops in an open position tremendously favor Black. White's best was to seek a stale symmetry where Black's slight initiative would find no targets.
It may be that Apesenieks thought this combination, which essentially eliminates the queenside pawns, would secure him a draw for his team.
An instructive mistake would be 16. Rxb5? Ba6! when there will be essentially a cross-pin on the Bishop at e2 which is overloaded by guarding the diagonal to f1 and the Queen (though 16... Qxd1 also works) when 17. Rb4 (17. Qxd8 Rxd8 18. Bc4 Bxb5 19. Bxa2 Bxf1) 17... Qxd1 18. Bxd1 Bxf1
A deceptively simple position, but far from equal. Black'sadvantage has nothing to do with the pawns, which are symmetrical. It is all about his superior pieces (a Rook on the 7th and the two Bishops on their best diagonals) and White's lack of good squares on which to deploy his. At the moment, White's Rook and Bishop are quite insecure.
"The position begins to be very interesting" notes Maroczy.
White's Bishop must retreat, but it has no secure residence.
Black takes a moment to create luft for his King. The move is passed to White, who realizes he has absolutely no good way of investing the tempo, which may have been the psychological pressure that led to his mistake...
Walking into an unfortunate pin, but the alternatives were not appealing either. White's Queen has too few squares.
The Black Queen finds her way to the kingside for the final assault via the diagonals that White cannot secure.
