1... Qe5 2.Qe5:+ Kc6: 3.Qd6#
(1... Qg5 2.Qf3+ Ke6 3.Bc8#)
Beautifully constructed threemover with three changed lines. The try is a superior phase not because the more attractive play, but also for a subtle refutation which paradoxically self-block the flight given by the first move.[MV]

1... Bc8 2.e5 ~ 3.Sg3:#
1... Bd5: 2.ed5+ Be5 3.Qe5:#
Theme "Raumungsopfer" in threat and two main variations and good by-play. The role of WBa8 is marginal.[MV]

Minor dual 1... Rc6 2.Rc6: Rad1 3.Rc1 (as 1... Rb6: 2.ab6 etc) or 3.Rd6 (4.R:R) Re1/Rc1 4.Rd7:/Re6:!
The key is appealling, of course, but the composers hope that the ensuing play will be of some consolation.[A]
Somehow straight-forward opposition WR v. BR duel.[MV]

1... ed6 2.Bg4 (~ 3.Sd3+ Ke4 4.Rd4#) 2... c5 3.bc6 ep ~ 4.Sd3+ Ke4 5.Rd4#
Two variations with obstructions on d6 are not thematically quite ballanced, the first one with the WS sacrifice and a self-block being more appealing[MV]

4.Qd6! Ke4 5.Qd7! Kf4 6.Qg4#;
4... Kf4 5.Qg6! e4 6.Qg5#;
4... e4 5.Qe7! Kf4 6.Qg5# - active WQ.

2... Ke4 3.Kg4 h5+ 4.Kg5 h4 5.Kf6 h3 6.Qe5# - active WK.
The first solution, though also simple, is much better due to three different quiet branches. The play is, however, totally accurate.[MV]
