Blunder (20)

Black's last move 16.- Qe6-b6?? was really bad in Werle - Bartel (Bundesliga 2010).

17.Nxc4! (17.Bxc4 was also good) dxc4 (17.- Qxb5 18.Nd6+) 18.Qxf5 and White had no problems to make use of the won pawn, 1-0, 30.

Blunder (5)

In the diagram position (Bartel - Marjanovic, Kavala 2009) White played 28.Rxb7?? A really bad move.

How the game was continued: 28.- Qf4! (forking rook and knight) (0-1, 31.).

Tactics (7)

The last moves were 1.Rd3-d7 Kh7-h8?? How did White close the game in Bartel - Malakhatko (Lublin 2009)?

Solution (diff. 2/5): 1.Qd4!! 1-0 (Black was that shocked by this move that he resigned. Obviously 1.- Bxd4 2.Bxd4+ Kg8 3.Rg7+ is dead lost, but Black could have played on with 1.- Qg8, after which the computer gives 2.Rf6; the position is lost anyway, but not that obvious).
