Qxe5, black can give some problems with the d-pawn and attacking the white king. It looks fairly equal, IMO. If 3. Qxf3, black also gets an attack on the white king. - 3. ...Nxf2 4. Qxf2 Rxg3+ 5. Kf1 Rxh3. I'm sure black will at least be able to get a perpetual out of this. I'm going to let it run for a while to check both of these lines - I could be wrong. :) Jeremiah
