Solution of problem 59
White: Kf2, Qd1, Re3, Rb7, Bc1, Bd3, Pa2, Pc2, Pf3, Pg4
Black: Ke8, Qd4, Rd8, Rh8, Bg2, Nd5, Pa7, Pc6, Pe6, Pf7, Ph6, Ph7
White has less material on the board and his e-rook is pinned. However his pieces are more active, therefore he should keep the initiative until he gets some decisive advantage.
Note that 1.Bb2? loses the exchange as it can be answered by 1...Nxe3 (not 1...Nc3? 2.Qd2! wins at least the knight) 2. Bxd4 Nxd1+ 3.Kxg2 Rxd4.
1. Bg6 !!
Brillant move that sacrifices the queen for a powerful mating attack. Most continuations fail:
a) 1...Qxd1 2.Rxe6+ Kf8 3.Bxh6+ Kg8 4.Bxf7#.
b) 1...Qxe3+ 2.Bxe3 fxg6 (if 2...hxg6 3.Qd4 wins) 3.Bc5 prevents Rf8 and threatens c4.
c) 1...Qf6 2.Bxf7+ Qxf7 3.Rxf7 Nxe3 4.Qxd8+! Kxe8 5.Bxe3 followed by 6.Rxa7 or 6.Kxg2.
d) 1...Nxe3 2.Bxf7+ Kf8 3.Qxd4 Rxd4 4.Bxe3 and Black cannot cover h6.
1. ... Ne7
The best answer.
2. Qxd4 Rxd4
3. Rd3 ! Rd8
The exchange is not good: 3...Rxd3 Bxd3 and Black will lose more material.
4. Rxd8+ Kxd8
5. Bd3
Not 5.Bxf7? Rf8 followed by Bxf3 if the white bishop moves.
5. ... Bh1
6. Bb2 Re8
Or 6...Rg8
7. Bf6
Black is in zugzwang.
Use pins and prophylactic moves to restrain your opponent. This will give you a comfortable game and plenty of tempo.
Problem 60 - Thrust
White to play and win
White has a clear material advantage and should win the game. However it is not as simple as it looks and Black still has hope for a draw as his bishop and king can hold the position well.
