Tactics (38)

White to move had a very good idea in Bischoff - Meijers (Bundesliga 2010).




Solution (diff. 3/5): 1.Be6!! Rxc3 (1.- fxe6 2.Rc7! Rxc7 3.Rxc7 Qxc7 4.Nxe6+) 2.Bxd7 Rxc1+ 3.Qxc1 Rxd7. The material is equal but the white queen is stronger in this position than the uncoordinated black pieces. 4.Qc4 Ba6 (Qb5 was the threat) 5.Qc3 Bb7 and with d5+, d6 it is clear that the black position is a mess. 1-0 ten moves later.
