Bh3 is not the move for white however... that leads to a repetition. white >plays c5 to stay on the track to mating... Bh3 will also mate, but only after >going through the 2-fold repetition first, and wasting time... I apologize if i was wrong here, but i just cant get it. I saw 3.c5, but after 3...Kxf1 4.cxd6 f2 5.d7 K(e2) 6.d8=Q f1=Q a queen-ending with a pawn up for white follows. Could you (or Bruce Morland) give some further moves of the best line? Is it a forced queen swap or what?? If white simply waits for ...f2 with 1.Bc8 black will never get a queen. It is really hard to believe... Oliver
