2009-12-08 19:22:34drad1651the moves following the tactic are interesting too 
2010-02-08 13:01:59memo1598Crafty continuation notwithstanding, most players would win Q for R with 4.Re8+ or 4.Rd6+

2010-11-16 21:44:06grom431861What if 3...Qb8? 4.Rxf6+, then what? Also, I'm with memo on 4.Rd6+ which is what I planned... 
2011-10-17 23:21:23chessisajedrez1758I thought ... Qd2 saved game; missed Rd6+ and captures in d2. Looks simple but complex.

2014-12-01 20:32:44nune1565Very nice one showing the power of setting up a discovered check. @grom43, if 3...Qb8 4.Rxf6+ Kh8 5.Rh6! gxh6 6.Qd4+ then mate. 
2015-03-16 17:23:08grom431861@nune, 5.Rh6! nice one. OK, if there's a 6.Qd4+ in that line, how about what to do if 3...Qd8? 
2015-03-16 18:25:28nune1565@grom43, if 3...Qd8, white just has to settle for winning the queen with Rd6+, with a small advantage (nominally up a pawn). 
2017-10-08 22:18:27grom431861A year or so later, went through analysis again. It seems we agree that Crafty line below after 3...Qd8 is not what we want to do.
