US Championship 2015, round 5

The following position arose after an edge of your seat game with sacrifices, blunders, come backs and time pressure; both players went for the win and one (black) got rewarded when white went for the natural hiding of its King after being attacked for most of the game.

Women WCh 2015 - Final (3-4)

There are 2 games available; please select them from the drop down menu over the chessboard!
Mariya Muzychuk (UKR) is the 15th Women World Champion; congratulations! She defended her 1 point lead from game 2 with two highly combative draws in games 3 and 4. Natalija fought very hard to win a game: a) Game 3: the madness started with 12.e4 ... and lasted pretty much the whole game; still black held on with 3 pawns for a piece b) Game 4: black tried to take advantage of the aggressive play on the King side by white with 15.f4... and 19.g4 ...; however black did not seem to have enough firepower left and after 39.Re7 ... I believe white was better. Mariya sacrificed a piece for a couple of pawns with 41.Bxf7+ ... followed by an exchange sacrifice with 49.Kd5 ... Once that happened, the material advantage black had (Rook for 2 pawns) was just symbolic

Women WCh 2015 - Final (2)

The second game of the final was a Ruy Lopez. It was a long positional battle as one would expect. Mariya was white and maintained for a long time a positional advantage. This forced Natalija to use a lot of time in order to find the proper defence. Mariya increased the pressure and in time trouble Natalija could not hold the position against the final assault on her King. Notice how black completely forgot about Bb7!

Women WCh 2015 - Final (1)

Natalija and Mariya are unlikely finalists, facing each other in a 4 games match with possible tie break games in case of a tie! The first game was very quiet with both players content to play cautious, exchange pieces and reach a draw. Those interested in the Anti-Meran might like to save it to their database for reference.

Women WCh 2015 - Semifinals (2)

After yesterday masteful endgame display by Pia, Natalija had to win. It is remarkable in this situation Pia decided to play the Sicilian and put a lot of faith into a Queenside dominance. This however resulted into negligence on the Kingside! Natalija correctly observed it and after good preparation it began the final assault with a swift attack. Her win tied the match; well deserved result for Natalija!
