2012-03-12 18:56:26SirRick1703I found Qg3, but Rf5 was an impossible (and amazing) one! 
2014-06-26 11:05:09BadMamaJama1284I got the first move too. discovers a devastating attack on g7 by the Q, so, black must control g7 at all costs. White may then take a R. E.g. if 3 ... Rf7, QxR. 
2015-08-31 22:28:43grom4318453.Rg7 R4f7! holds. Missed this. And 3.Ne4 R4f7 4.Qc3+ Ne5 (or f6)? Missed this as well. On the third try, I stopped looking at the wrong idea and found the correct one. Next time.
