I don't see how to report a problem with a Tactics Trainer puzzle, so I'm posting here. If someone can provide a URL for me to report the problem, I'd be grateful.
Anyway, reversing the move order is just as effective as the only solution accepted by the server. I.e., the server only accepts 1 ... Rb1 2 Bxd6 f3+ 3 Kxf3 Rxb3+, but 1 ... f3+ 2 Kxf3 Rb1 is equally effective.
