2008-02-18 19:55:57Milacek1733excellent ... clearly better than Rh7+ 
2008-05-27 07:58:44Tama1730i dont understand Bb2+ was the first move i saw????? WTF 2200?????  
2010-06-06 04:51:33grom431839@ Milacek. Really? Clearly better? 2 Bb2+ is better, certainly, but 2 Rh7+ is pretty strong. In ten seconds.

2010-11-23 14:52:57Garryback16795.12 for Bb2 4.41 for Rh7+ after 90 minutes 15 plys it is very close and can´t be judged within 3 sec.

2011-12-14 03:14:33NoConception1912Terrible problem, Rh7+ is also winning. 
2015-07-27 11:44:51Improchess2051adding a neutral piece for black (a white-squared bishop) would make this problem excellent. 
2015-07-27 17:04:30grom431839@Improchess means this to eliminate the dual (now the move Rh7+ isn't so good). Is that right? 
2015-07-28 16:47:46Improchess2051@grom43 Right 
2017-05-10 17:03:37goldenrule1900Bb2+ leads to checkmate. 
2017-08-14 16:17:56colinp1697Dep Rybka actually prefers Rh7+ (after a minute or so) 
2017-08-14 19:33:13chessisajedrez1743A dual to me. Stockfish considers Rh7+ better too. I replayed both solutions with Stockfish to find out they are theoretical complicated wins. The type that can be easily misplayed in quick play.
