This offer to exchange queens is a mistake.
At the cost of a pawn, White can now establish
a dominating position and penetrate dangerously
into the black position. However, with
careful defence Black should have been able to
hold the position. For example, I ... iWe7 2 iWa6
'&°f6, with counterplay, came into consideration.

the immediate 4 ~c7? is premature because of

The variation that Black worked out is completely
plausible. However, there is a critical
improvement near the end.

The knight fork on c3 now no longer works. If
he had simply made another couple of moves,
this way out would surely have come to mind.
White cannot win the resulting knight endgame;
