White suddenly realises if he wins this game his grade will go higher than 1900 and as
he wants to play in an under 1900 tourney he must lose.
He is so far ahead in material He cannot resign without attracting attention
to his sandbagging ways so he forces Black to mate him.
(a study by J. R. Harman. White to play and commit sui-mate in 10 moves.)
1. Qg6+ {First step: Get the Black c-pawn rolling and the Black King to g3. All of the Black moves are forced.} 1... Kh4 2. Kg2 c6 3. Kg1 g2 4. Ne6 c5 5. Ne5 c4 6. Bd2 c3 7. Bg5+ {Pushing the Black King onto g3 to set up the sui-mate.} 7... Kg3 8. Nf4 c2 9. Qb6 {Now a Queen or Rook promotion is mate in one. Taking a Knight 9....c1=N 10.Ne2+ Nxe2 (only move) Checkmate. So...} 9... c1=B 10. Qe3+ {Black has only one move.} 10... Bxe3 {Checkmate. Damn clever these sandbaggers.}
Are you sure the study is by Harman? Richard Harman is well known for inventing a system of cataloging studies (useful for judges who wanted to check that a study was new) but I didn't know that he created any studies himself.

15. dxe4 {Open up the d-file so Black can play....} 15... Bxg3 16. fxg3 {Which allows White to expose his King to a check. Also the White Queen is covering h5 preventing a Knight from going there.} 16... Rxd1 {So the Queen is sacced to allow Nh5.} 17. Rxd1 Nh5 {See previous note.} 18. b5 {White unprotects the c5 square allowing Black a Queen check} 18... Qc5+ {Kf1 does not allow mate in one.} 19. Kh1 Nxg3# {Beautiful. The hidden skill is making it appear like inexperienced play when infact White was brilliantly lured into giving this checkmate. I have thousands of games like this on RHP. Playing over them is driving me slowly insane.}
But the lads on here are all expert sui-maters. They have it down to a fine art.
