2007-06-22 17:34:57Chessdoom1604Excellent! (and ofcourse I had it correct :-) 
2008-08-06 15:58:56Hyperbeam1613I missed it. 
2008-08-08 15:29:07gigagajt1909very nice 
2008-08-18 19:56:24Hyperbeam1613Argh...!! 
2009-01-13 02:56:51Coventry1613wow, I'd never seen that 
2009-01-27 08:51:16UriBlass18886.9 seconds almost missed it and thought to play 2...Bh3+ 
2009-10-08 15:05:49Schumi1546Very nice, didn't see it.  
2009-11-25 14:00:23grom431828Excellent problem. "Strike whilst iron is hot" 
2010-05-30 15:25:02JoshBrack1627failed it. missed the queen sac yet again i can't seem to see a back rank mate anymore. :( 
2014-06-06 23:01:10chessisajedrez1731I don't get tired of this maneuver. 
2015-01-15 18:59:48Bisonratte1549attraction, mating with R+B 
2017-01-31 20:29:34chessisajedrez1731The maneuver is more common with a defender blocking the Q/R check in f1, then the Q/R sacrifice, etc. IMO, ironically, it's more difficult to spot when no piece blocks the check.
