Find the Losing Move

 White to move

Can you guess what White played in this position?   Amazingly, in the first round of the U.S. Championship 2012 yesterday, Stripunsky played 11. d3?? and resigned, giving Onischuk the full point.

So....don't beat yourself up over whatever blunder you may have made in the Quads last weekend.  It could have been worse.
