A Great Game

Tonight, I played a great game. As a result, I will show you the game in its entirety. I am Black.

1. f4 Nf6 2. Nf3 b6 3. e3 Bb7 4. d4 e6 5. Bd3 g6 6. O-O Bg7 7. c4 d6 8. Nc3 O-O 9. e4 a6 10. Re1 Nbd7 11. h3 c5 12. d5 Nh5 13. g4 Nhf6 14. Kh2 (see 1st diagram)

I am very proud of the next move. I sank into a very long thought here. Guess what move did I play in the end? And this candidate move was not easy to see but easy to calculate.

The answer can be shown by highlighting between the brackets.

[14.... Re8!! (that's right I blocked my f6 Knight's only escape route to entice the e-pawn forward, I know what you're thinking... wth?!) ]

Now watch the drama unfold.....

15. e5 dxe5 (now all the moves are forced and I had calculated all of this beforehand)
16. fxe5 exd5
17. exf6 Rxe1
18. Qxe1 Qxf6

Here my opponent slipped up. He played

19. Ng5? Ne5
20. Qg3 (see 2nd diagram on right)

And now, it is my turn to slip up. I played

20... Re8

However, there is a stronger move.

20. .... Nxd3! And the Knight surprisingly cannot be taken by the White Queen. ie. White cannot play 21. Qxd3. Can you figure out why?

The answer can be shown by highlighting between the brackets.

[That's because this leads to a discovered attack 21. Qxd3 Qf2+ 22. Kh1 dxc4+ and the White Queen is lost]

21. Nxd5 Bxd5
22. cxd5 (see 3rd diagram on right)

and now the final nail in the coffin....

22... Nxd3
23. Qxd3?? hastens the end although other alternatives are just as bad as 23. Bd2 Re2+ wins the bishop with a crushing attack to boot.
23... Qf2+
24. Kh1 Re1+
25. Qf1 Rxf1#
0-1

A terrific finish. My opponent was gracious enough to allow me to go onto checkmate.

I checked my analysis with Fritz and barring the slip on move 20. The 14th move was the best way to equalise in that position.
