Here I am mating, but if we go back a few moves it seemed improbable: Here several things have to happen order for me to win. The danger is that if I lose the queen or the rook and my partner gets mated. If my partner's opponent stalls, he would probably win. Also if he plays Qd3 and I get the rook instead of the queen, I probably don't mate. This was another mate, with my partner giving me the critical move: In this position I sacced my queen. Yes it was a real queen. I thought, probably incorrectly, my partner was lost, and this was a desperation shot. I sacced the Queen on f7 and played R@g7+ Here I played @g2, which might be too slow. My opponent played @g6, probably to cut off my protection of the g-pawn, but this fails to defend his king: Here my partner suggested Bh6, which won!
