TCh-CHN  2016.7.24 .  Position after 39 moves. White has outplayed his rival and has actively posted each and every piece. Now is the time to cash in.

WHITE TO PLAY AND WIN MATERIAL!

Karpov Poikovsky  2016.7.24  Position after 24 moves. A very unusual position, especially for Grandmasters! Both Kings are in the open, but Black is up a Rook and piece…In this kind of game, the initiative is everything.  In the game continuation White decided to win back some material with 25.RxN(?), but after 25…g5! White’s position collapsed like a house of cards.  INSTEAD, from the above position, White has a much stronger continuation, giving some winning chances.

WHAT IS WHITE’S BEST MOVE?

Lake Sevan  Martuni  2016.7.21 Position after 20 moves. White had sacrificed a piece for the attack, but now what to do?  If 21.e5?! Black beats back the attack with 21…BxB! 22.QxB Ng4+ 23.K-moves Qf5!  Or if 21.Bxc8?! Rxc8 22.d5?! PxP 23.NxP (23.cxd5 Rxc3!) Rxp+ with a mating attack.

WHITE TO PLAY AND CRUSH!

Lake Sevan  Martuni  2016.7.20  Position after White’s 43rd move. A fascinating and wild game! Both sides are trying to win, material even but unbalanced. In such positions the initiative is everything. Wrong now would be 43…Qc3? as 44.Qb8+! Ke7 45.Qd6+! wins. Better would be 43…Qa1!?, but things are still messy after 44.Kg2 as taking the Bishop would allow a perpetual check starting with Qb8+.

BLACK TO PLAY AND WIN!

27th Czech Open Pardubice 2016.7.23  Position after 20 moves.  At first sight, a complex fight with opposite-side castling. If now 21.Bd2!?, with the idea of 22.Rc1, then 21…Kb8 is anybody’s game. Black must have felt confident about his chances in this position above…

WHITE TO PLAY AND WIN!

27th Czech Open Pardubice 2016.7.23  Position after Black’s 24th move (24…Nb4). White had sacrificed his h-pawn to open the h-file and build up an attack against Black’s King with a later Rh1.

Black’s last move aims to exchange White’s light-colour Bishop. If White now plays 25.BxN BxB 26.Nf4, then 26…RxR and 27…Bf8 will give a sufficient defence against White’s Kingside initiative.

WHITE TO PLAY AND CRUSH!
