The Women's World Chess Championship was held from 16 March to 7 April 2015 in Sochi, Russia. It was a 64-player knockout tournament. It was originally scheduled from 11 to 31 October 2014 but problems in finding a sponsor and host city eventually forced international chess organisation FIDE to announce the postponement of the Championship on 24 September 2014,[1] scheduling it for early 2015 in Sochi.[2] The unclear state of the tournament was highly criticised by the Association of Chess Professionals (ACP).[3]
In the final, Ukrainian Mariya Muzychuk, seeded 8th, defeated Russian Natalia Pogonina, seeded 31st. As a result of this victory, Muzychuk was awarded the title of Grandmaster (GM), qualified for the FIDE World Cup 2015, and earned the right to defend her title in a 2016 match against the winner of the Women's FIDE Grand Prix Series 2013-14, Hou Yifan.
The players were selected through national chess championships, zonal tournaments and continental chess championships. 51 players from women's continental and zonal qualifiers:[4] Europe 28,[5] Asia 12, Americas 8 and Africa 3.
The qualified players were announced on 22 January 2015, subject to signing the contract.[6]
Three former world champions were in the field: Alexandra Kosteniuk seeded 5th, Antoaneta Stefanova 9th and Anna Ushenina 15th. Notably, women's world number one and defending champion Hou Yifan from China opted not to play, because of a prior commitment to a chess tournament in Hawaii.[7] [8] Also absent from the world top 10 were Nana Dzagnidze and Kateryna Lagno. (They were replaced by two spots from E13.)
The participating players were seeded by their FIDE rating of March 2015.
Two days per match were followed by possible tie-breaks on the next day if the match was tied. The only rest day was 1 April the day after the semi-finals.
The total prize-money was 450,000 US dollars, the same as in 2010 and 2012.[9]

The final was the only match of the tournament which consisted of four classical games (from 2 to 5 April 2015), played on consecutive days with a rest-day between the semi-final tie-breaks and match 1. Eventual tie-breaks, if needed, were scheduled to play on 6 April 2015, in the same manner as the whole tournament: two rapid games (25+10), i.e. 25 minutes for the whole game plus 10 seconds increment, the two rapid games (10+10), two blitz games (5+3) and an armageddon decider.
Pogonina had the white pieces in the first game. Before the final they had met only once, in the 2007 European Individual Chess Championship, which ended in a draw.[10]
In the final game 4, white pieces belonged to Muzychuk, who opened the game with her favorite 1.е4.[11] Pogonina responded with her favorite 1...е5.[11] In the Scotch Four Knights Game she tried to avoid the main variations by putting the bishop to b4 via c5.[11] The idea allowed Black to duck the home preparation of Muzychuk.[11] White, however, achieved a spatial advantage and overall more favorable game after the opening.[11] Later White decided to advance kingside pawns, weakening own king.[11] The Black also had pawn weaknesses and a sharp and dynamically balanced position emerged. On the move 41 Muzychuk carried out a simplifying combination, transposing to an endgame with two strong passed pawns against a knight.[11] Pogonina was left with no winning chances, and the game ended in a draw on the move 56 after the move repetition.[11]
