This position is from the first round game of Ivan Cheparinov and Vasily Papin in the recently completed Aeroflot Open 2011. Black has just played 18... h6 to push the pesky bishop away. Is the frocked one out of a job? How would you play as White?
See if you can spot the move, then play over the whole game score after the break.
