Post 726 Key move 1.Kb7
Post 727 Key move 1.Qg7, Kb1 2.Qg6+, Ka1 3.Qf6, Kb1 4.Qf5+, Ka1 5.Qe5, Kb1 6.Qe4+, Ka1 7.Qd4, Kb1 8.Qd1 mate. The black king can go to c1 but it shortens the process as once the queen gets to the D-file it then goes to d1 or d2 mate.
Post 728 Key move 1.Qf6 and then Qh4+ and Qxb3. The mate takes longer if the black king abandons the pawns but its just a process of bringing the white king across to help in the mate.
Post 729 Key move 1.Rf2
Post 730 Key move 1.Qf4, d1=Q or R or B 2.Qf2 mate. if 1....d1 =N 2.Bd2 mate.Leave a comment:

Post 721 Key move 1.Nc2
Post 722 Key move 1.Nc2 but not 1.Ne3 or 1Ng2 as the bishop can stop the knight mates. On 1.Nc2 the bishop can stop Na3 mate or Ne3 mate but not both.
Post 723 Notice I have placed the knight on key squares around the black king focus on c4 to deliver checkmate: There are many.
Key move 1.Nd1
Post 724 Key move 1.Qh8 the bishop discovered check (in one variation double check) and the bishop blocking the rook attack are key to this problem.

Post 698 Key move 1.Rb8
Post 699 Key move 1.Rd2 if Nxd2 2.Nc1 and 3.Nb3 mate or 1...Nb3+ 2.Kb3 and 3.Rxa2 mate or 3.Rd1 mate, depending where the black knight moves.
Post 700 Key move 1.Rb6! only this move stops the black rook from blocking mate in two (and also threatens Rb8 mate) if 1...axb6 2.Ra4 mate.Leave a comment:
