Problem M73

Black to move after 1.Bg2 (***): (D)

Threat: 2.Bxe4, winning the bishop. If 2.Rxe4?? Qxd2.

Prevention: 1...Rxc3! Now Black threatens to capture on e3, and all of White’s captures lose:

• 2.Rxe4 Qxd2;

• 2.Rxc3 Qxd2;

• 2.Bxe4 Rxe3; and

• 2.Qxc3 removes the guard on g2 and allows 2...Qf1+! 3.Kh2 Qxg2#

Relatively best for White is 2.Rd3, but after 2...Qxd2 3.Rxd2 Rxh3+, Black is winning rather easily.

Problem M74

Black to move after 1.e5 (***): (D)

Threat: 2.exf6, winning the knight.

Prevention: 1...Nh5! Yes, this violates “Knight on the rim, your future is dim/ grim” but it makes a lot of sense: 1...dxe5 opens up the center when White has a rook on d1, Black does not have a rook on the d-file, and Black’s king is in the center. 1...Nd7 is not as flexible as 1...Nh5, especially since the latter creates a threat of its own, 2...Ng3. And the knight is a good blockader on h5, where it cannot be attacked by a pawn. Of course, these kinds of positions call for concrete analysis, so at 12 ply, Fritz rates 1...Nh5, which I played, as over a half-pawn better than the alternatives.
