The Cunningham Defence.

4. Bc4 Bh4+ 5. g3

Richard Proctor called this the Wild Cunningham Gambit - it certainly lives up to its description !

5... fxg3 6. O-O gxh2+

Here or on the next move theory suggests Black is better playing ...d5.

7. Kh1

This is sometimes called the Three Pawns Gambit. White's King is in fact quite well sheltered behind the Black h2 pawn.

7... d6 8. Bxf7+ Kd7 9. e5 Nh6 10. e6+ Kc6 11. Nd4+

11.c4 may be better here. White is threatening 12.Qa4. Now if Black plays 11...a6 12.Qa4+ Kb6 White captures the Knight with 13.Nxh4 when Black cannot reply 13...Qxh4 on account of 14.c5+ discovering an attack on the Queen.

11... Kb6 12. Nc3 c5

Black should only push this pawn one square, when he would have reasonable chances of surviving the onslaught. After the text move mate is inevitable - to be precise Fritz gives it as mate in six.

13. Nd5+ Ka5 14. b4+ cxb4 15. a3

A slightly quicker way to mate was with either 15.a4 or 15.Qe2, but this still does the business. After 15.a3 White is threatening to mate immediately with 16.axb4.

Richard Proctor showed a few sample mates.

(a) 15...axb3 16.Rxa3 mate

(b) 15...b3 16.Nxb3+ and now

(b1) 16...Ka4 17.Nc3 mate

(b2) 16...Kb5 17.Qe2+ b5 (17...Kc6 18.Qc4 mate)

18. a4 Kb7 19.Qxb5+ Qb6 20.Na5 mate.

In variation (b2) Black can prolong the agony with different moves on his 18th but defeat is still inevitable. See if you can work it all out!
