   The World Chess Championship 2012 was a chess match between the defending world champion Viswanathan Anand of India and Boris Gelfand of Israel, winner of the 2011 Candidates Tournament. 

 

   After sixteen games, including four rapid games, Anand retained his title. The match, held under the auspices of the World Chess Federation FIDE, took place between 10 and 30 May 2012 in the Engineering Building of the State Tretyakov Gallery, Moscow, Russia.  The prize fund was US$2.55 million.

 

   Anand was the defending champion, having gained the title in 2007 and defended it in 2008 (against Vladimir Kramnik) and in 2010 (against Veselin Topalov). Boris Gelfand became the challenger in 2012 after winning the eight-player 2011 Candidates Tournament. Anand's subsequent victory, therefore, was his third consecutive title defence.

 

   The match conditions called for twelve games to be played with classical time control. If a player scored at least 6½ points, he would be declared the winner and the match ended. By the end of the twelve games, however, the match was tied at 6 points each, so four rapid games were played in order to produce a result. Anand won the rapid-game playoff with a win in the second game and draws in the other three games.

   Answer:

 

 

   The black queen now has no escape squares, and white can play a move like 18. Bh3 or 18. Bd3 on the next move, discovering an attack on the queen from the rook on b1.

 

   White should not play the discovered attack with the bishop and rook right away, because the black queen could escape to f3 if played too quickly.  For example 17. Bd3? Qf3.

 

 

   Happy Tactics!
