1. d4 d5 2. e3 e6 3. g3 c5 4. dxc5 Bxc5 5. a3 Nc6 6. Bg2 Nf6 7. h3 b6 8. Nf3
Ba6 9. b4 Bd6 10. Nc3 b5 11. a4 bxa4 12. Rxa4 Bb7 13. b5 Ne7 14. Bb2 Nf5 15.
O-O d4 16. exd4 Qe7 17. Ne5 Bb4 18. Bxb7 Qxb7 19. Qd3 Bd6 20. Ba3 Bc7 21. Ra1
O-O-O 22. Qc4 Rxd4 23. Qb3 Bxe5 24. Bc5 Rxa4 25. Rxa4 Rd8 26. Rxa7 Qf3


27. Ra3 Bxg3

I didn't know why he retreated his rook, but pressed on:
From here I sacrificed a bishop to rip open his castle.
I was unsure if I really had anything.
28. fxg3 Qxg3+
29. Kf1 Qxh3+
30. Ke1 Qh1+
31. Ke2 Ng3+
32. Kf2 Rd2+
33. Kxg3 Qg2+
34. Kf4 Qg4+
 35. Ke3 Rg2
36. Kd3 Qf3+
37. Kc4 Rg4+

  Now I was hoping to either trap him or trade off the queens,
and take a chance on the endgame.  He was as slippery as
a piece of soap!  I couldn't sustain the checks, and thought
the tables might turn at any moment....

38. Bd4 e5
39. Kc5 Nd7+
40. Kd6 Rxd4+
41. Ke7 Qf6+
42. Ke8 Qd8+

I chased his king all the way to mine,
but still couldn't see how to pin him down in the smoke of battle:

43. Kxf7 Rf4+
44. Ke6 Rf6+
45. Kd5 Nb6+
46. Kxe5 Qd6+
47. Ke4 Rf4+
48. Ke3 Qe5+
49. Kd3 Qd4+
50. Ke2 Rf2+
51. Ke1 Qd2# 0-1

Finally, after chasing all the way back to his side,
I squashed him into the back row.
I had to figure out an enclosing technique with queen and rook,
on the fly!   You almost never get to do these things in games,
because the mate comes too quickly or the player resigns.

Not a great game I admit, but really fun!
