Black to play and win

Doofen- AWB,ICC 3 min blitz, Oct 2014

Solution

A few motifs fit together. The g2 pawn is pinned by the Bc6, so doesn't protect the Ph3. So the Re3 is tied to defending the Ph3, but also has a role defending the Be5. There is a jump biff Qh6-e3 so the Pf4 is pinned, and once the rooks on e1 are exchanged, the Re3 is no longer protected by the Q, and is thus LPDO.

So, 1…Re1+! 2 Qe1 Re5! and if 2 Re5, Qh3+ and mates; or if 2 fe, 2…Qe3 is 0-1. In the game, I saw these ideas, and played 1…Re5! with precisely the same idea, and it wins in the same way.
