10. Ng5 {Black can fight on here with 1...Nh6 but all Black can see is the Queen winning fork Bxf7+} 10... Qf5 11. Nxf7 {And now 2...Na5 keeps the game in the pot.} 11... Nxe5 12. Nxe5 {Swaps the piece in play rather than take the h8 Rook and sets up threats down the open e-file. A chess player.} 12... Qxe5 13. Bxg8 dxc3 14. Qf7+ Kd8 15. Qf8+ Qe8 16. Bg5# {Mate with the King and Queen trading places. What do we call this?}

1. e4 d5 2. exd5 Nf6 3. c4 c6 {This gambit gives Black good play.} 4. dxc6 Nxc6 5. Nc3 e5 6. h3 Bc5 7. Nf3 e4 8. Qe2 O-O 9. Ng5 Bf5 10. Ngxe4 {OOPS! But White's position was difficult and just waiting for accident to happen.} 10... Nxe4 {Now White realises he cannot take twice on e4 due to Re8 so he moves the King from the open e-file.} 11. Kd1 Nd4 12. Qe1 Nxc3+ 13. bxc3 Bc2# {And there is our, as yet, unnamed mating pattern.}

1. e4 e5 2. f4 f5 3. exf5 exf4 {Copying moves as Black on an open board often leads to trouble.} 4. Qh5+ {This is the trouble I mentioned, Black cannot copy this move.} 4... g6 5. fxg6 Nf6 6. g7+ Nxh5 7. gxh8=Q Qh4+ {OK Black can copy this move.} 8. g3 fxg3 {Now Black was perhaps hoping for 9.Nf3 g2+ 10.Nxh4 gxh1=Q when we have a pure mirror position but with White to play when11.Qe5+ wins a piece.} 9. Qe5+ Be7 10. Bg2 gxh2+ 11. Ke2 Ng3+ 12. Kd1 hxg1=Q+ 13. Qe1 {It's a disaster. 13.Rxg1 was the move.} 13... Qg4+ 14. Bf3 Qxf3

Bc2 Nb6 12. b3 Nb7 {Black's messing about with the Knights have cost him his e-pawn.} 13. dxe5 f5 {So rather than lose a pawn and swap Queens Black turns it into a gambit.} 14. exd6 Nxd6 15. e5 Nf7 16. Ba3 Be6 {White should chop Queens here as it either wins the exchange or the e7 Bishop.} 17. Nd4 Bd7 {Now Black is struggling. The coming pawn fork on e6 wins material.} 18. Bxe7 Qxe7 19. e6 Rfe8 {This does not pin the e-pawn. White can take on f7 with CHECK!} 20. Nxf5 {But this appears to be just as good. Black has had enough of being pushed about so lashes back with a Queen sacrifice.} 20... Qxe6 21. Rxe6 Bxe6 22. Nd2 Rad8 23. Nd4 Bd5 {Black has nothing. He is a Rook for a Queen down. All he can hope for is that White totally relaxes and he concentrates on his other games. Indeed this is what happens...play on.} 24. Nf5 Ne5 25. Ne3 Bb7 26. Qe2 c5 27. Rd1 Rd7 {Undefended piece on e8. Is there a check in the position? Yes. So look for a two move trick. 28.Bxh7+ Kxh7 29. Qh5+} 28. Nf3 {White missed it too intent on chopping wood. You get the sense that White has chalked up 1-0 and is just giving this game a cursory glance.} 28... Rde7 29. Nxe5 Rxe5 30. Qg4 Bc8 31. Nf5 Bxf5 32. Bxf5 Nd5 33. c4 Nc3 34. Ra1 {No This is not the way, don't defend pawns, use your Queen 34.Rd7 that will force a Rook swap then it really is over.} 34... Ne2+ 35. Kf1 Nc3 36. cxb5 axb5 37. Bd3 Nxa2 {Now there is White's wake up call. There is one Black checkmate pattern in the position. Be careful.} 38. Bxb5 Re4 {All White need do now is give back the Queen 39.Bxe8 Rxg4 40.hxg4 would have been 1-0} 39. Bc4+ Kh8 40. Qd7 R4e7 41. Qc6 Nb4 42. Qxc5 Nc2 {Now is White's last chance before Caissa turns her back on this lad. 43.Qxe7 wins a whole Rook and with Ra7 coming this game is over.} 43. Rc1 {White was winning and missed many chances to bring the curtain down. Players losing a game of chess and playing on miss nothing. All they need is one chance.} 43... Re1+ 44. Rxe1 Rxe1{White has been checkmated.}

1. Bxe7 Qd3 {1...Qxe7 2.Rb8+ etc. The hanging back rank is Black's only chance.} 2. Rb8+ Kf7 3. Bf8+ {Clever stuff this. White’s plan is to get a Queen check on g7.} 3... Kg6 4.
