        Post 672 Key move 1.Qc4

        Post 673 Key move 1.Rb6!, cxb6 2.c3, b5 3.Kc5, b4 4.cxb4 mate

        Post 674 Key move 1.c4!, bxc3 en passant 2.Qc4 mate or 1...Kxb3 2.Qc2 mate.

        Post 675 Key move 1.Qc6! The thinking is White must have answers to Black's three different piece moves. The king can move to a6. The b - pawn can move to b4. The d-pawn can move to d6 or d5. Only Qc6 covers all three by mate on a8 or mate on a4 or finally if dxc6 (losing the queen) then Ra6 is mate. That is why you should follow the logical thinking otherwise the loss of queen will stop you from considering the move.

        Full solution: 1.Qc6, b4 2.Qa4 mate. or 1...Ka6 2.Qa8 mate or 1...dxc6 2.Ra6 mate.

        • Post 676 Key move 1.Nh1 The logic thinking is - what Black pieces can move? The H-pawn, the knight, and the G-pawn. If the knight moves then 2.Nf2 mate. if the H- pawn moves 2.Ng5 mate. if the G pawn captures knight and promotes to Q,R, or B then 2.Qg3 mate. if the G pawn promotes to knight then 2.Qf1 mate.

            • Post 686 Find Black's only piece move, than find the zugzwang move that leads to mate.

              Post 690 1.Bd5 and 2.Kf7 mate or Kg6 mate, depending on which piece the Black rook captures.

                  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.

                          Post 719 Key move 1.Nb5 or 1.Nd5 Black cannot stop the knight mates and Rdc4 mate at the same time.

                          Post 720 Key move 1.Na4 Black cannot stop one of the knight mates on b6 or b2.

                          • 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 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.
