No alternative: the semi-mirror variant

1.f25 - eg8
2.h67 - cd5?
Sorry, you need a Java enabled browser to view this Bushka problem!

This one was found by Demian Freeling. In the semi-mirror variant, white cannot perform a similar combination (with the idea of capturing the e-line). The reason lies eventually in the absence of a man on f3 (the man on h5 in the combination above). Leaving this man behind by capturing 3.f46x, leaves f4 vacant, and there's no go either.
