At first glance, you can deduce that white has an overwhelming material advantage. He is ahead by a rook and a knight. And it is his move. You might have already spotted that 30. Qd5 wins the rook because the e-pawn is pinned. But the truly neat move is 30. Nf5+. Both e and g pawns are pinned! How often do you get a position with two simultaneous pins in effect? Alright, so 30... Rf5 capturing the knight. Then, 31. Qf5!! And you have the same two pins again. Quite a gem.
