Blunder (15)

Position from Howell - Bindrich (Khanty Mansiysk 2010). Black with still 20 minutes on the clock played 29.- Nxe4??

White said: Thanks, and answered 30.Rd7! The mate with Bg7 cannot be prevented 1-0

Blunder (14)

It does not surprise me that the Chess Olympiad 2010 in Khanty Mansiysk offers some serious blunders.

In the game Lin (1736) - Can (2500) the following position arose with Black to move:

Black could have continued with 44.- Qxf4 45.Rxf4 Bxb2 and the thing looks kinda drawish. Instead Black played 44.- Bd4?? and White mated with 45.Qc7#

Ouch.

Tactics (37)

White to move wins in Zelbel - Gruskovnjak (Graz 2010).

Solution (1/5): 1.Qe6+ Qe7 2.Bd6! (2.- Qxe6 3.fxe6 and the threat Rf8# is deadly) 1-0
