"The key-move of a variation enabling White to recover his Rook. As we shall see
shortly, Black's winning maneuver initiated by 33.....Qd7+ comprises no less
than 20 moves!

Position after Black's 39th move...

[D]1Q3r2/5kpp/8/6P1/7P/8/1P4K1/2q5 w - - 0 8

40.Qb3+ ? Blunder " this is the only reason why the Combination worked according
to Dr. Alekhine.


It is astonishing that a master of the strength of Dr. Treybal, so conspicuosly
endowed with the imaginative sense, should not have perceived 40.g6+ the only
logical continuation, since any reply by black white could have found a forced
draw by perpetual check" according to Dr. Alekhine
