In a recent game, I saw a weaker player than me get a really good position. But then he decided to simplify to an endgame.
He made a positionally bad move and exchanged his good pieces for his opponents passive pieces.
In the diagram position, he could have played Ne4 , after which it is hard for his opponent to find a good move.
For example, Rad1 loses to Qxd1!
Instead, Black played Qd3 and White of course snapped up the opportunity to exchange the queens. His King position was very weak, but with no Queens on the board, Black has far fewer opportunities to attack.
The solution to last weeks’ problem is that White can draw with 1. Kd4 when Black cannot play a2 because of Bd4.
