Part I
- White to play and WIN!
- What is the fastest way for White to win?
- White to play and CRUSH!
- How should Black continue the attack?
- White thinks he is winning! WRONG! How should Black play?
————————- Part II
The following example is from the game Cheparinov versus Atakisi. The Bulgarian superstar had sacrificed a piece for two strong passed pawns. Just at the critical moment he overlooked a simple way to win the game:
- Cheparinov-Atakisi. Position after 35.e7. White’s passed pawns are more than enough compensation for the piece.
- 35…Bxe7!?. Probably best. If instead 35…Rd6 36.Qf8! wins
- 36.Rde1! Cheparinov did NOT play this strong move. It wins! Instead he played 36.PxB and had to win the game all over again!
- 36…Bf8!? What else? Cheparinov thought that this move would give Black the advantage!
- 37.f7!! Winning atleast an exchange, and certainly the game! It is easy to overlook simple things in complicated positions…
