Violent, forcing moves should be at the top of the list when looking for candidates. Here we see a position from Andrei Deviatkin vs. Alexandra Kosteniuk from the 2nd round of the recent Aeroflot Open 2011. White has just played 51.Bxg3 and no doubt is looking forward to trading down into an even endgame against the former women's world champion. Alexandra finds the move that sets up the win, though the actual game was eventually drawn. Can you see the right way to go in this position?
See if you can spot the move, then play over the whole game score after the break.
