Q × Q would have given White a decided advantage, enough to win with proper play. Mieses, however, feared the difficulties of an ending where, while having the exchange, he would be a Pawn minus. He preferred to keep the Queens on the board and keep up the attack. At first sight, and even after careful thought, there seems to be no objection to his plan; but in truth such is not the case. From this point the game will gradually improve in Black's favour until, with the exchange ahead, White is lost.

My plan for the moment is very simple. It will consist in bringing my Bishop around to B 3. Then I shall try to paralyse White's attack against my King by playing P - K R 3, and also prevent White from ever playing P - K Kt 5. Once my King is safe from attack I shall begin to advance my Queen's side Pawns, where there are four to three; and that advantage, coupled with the enormous attacking power of my Bishop at B 3, will at least assure me an even chance of success.

K - R 2 !
To prevent P - K R 4, which I would answer with P - K Kt 3, winning the Queen. It can now be considered that my King is safe from attack. White will have to withdraw his Queen via R 3, and Black can use the time to begin his advance on the Queen's side.
