The first game on the revised website. Marked by poor calculation in the middle game

1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 Nbd7 5. Qc2 c6 6. e3 Bd6 7. Be2 O-O 8. O-O dxc4 9. e4 e5 10. dxe5 Nxe5 11. h3 Nxf3+ 12. Bxf3 b5 13. Bg5 Be5 14. Rad1 Qc7 15. Rd2 h6 16. Be3 Be6 17. Ne2 a6 18. Nd4 Bd7 19. Be2 Bh2+ 20. Kh1 Bf4 21. Bxf4 Qxf4 22. Bf3 Rfe8 At this point my advantage is maximal. 22... c5 works better than I thought it would. 23. Ne2 Qh4 Here I am getting a little too confident. I was too bemused by visions of Bxh6 and spent too little time thinking of his effiective reply. 23... Qe5-+ 24. Ng3 Re5 another move made in a spirit of attack rather than with thought of his reply. 25. Rfd1 Bg4? 25... Ra7-/+ 26. Bxg4 Nxg4 27. Kg1? 27. Nf5 Qh5 28. f3 Nf6+/- leaves black with reduced mobility and white with attacks along the d file. 27... Ne3? The crucial blunder. I failed to spot the one viable reply. The more conservative 27... Nf6 puts pressure on e4 and maintains a -1.0 advantage. 28. Rd4 c5 29. Rd8+ Rxd8 30. Rxd8+ Kh7-+ I also considered 27... Nxf2 but in that case I DID see Qc3, which made me unsure. 28. Qc3 Nxd1 29. Qxe5 Ne3 30. Re2= 28. Qc3 Rxe4 29. Re1 b4 30. Qxb4 Ree8 30... Nd5 I considered this move, but, rather shaken by a reverse I failed to evaluate it properly. 31. Rxe4 Qxe4= 31. Rde2 f5?? The following is obvious in retrospect. 31... Reb8 32. Qa5 Nd5+/= 32. Nxf5 Qf6 33. Nxe3 Qf7 34. Qxc4 Qxc4 35. Nxc4 Rxe2 36. Rxe2 Kf8 37. f4 a5 38. a4 Kf7 39. g4 Kf6 40. Kf2 c5 41. Kf3 Rd8 42. Re4 Rd3+ 43. Re3 Rd4 44. b3 Rd1 45. Nxa5 Rd4 46. Nc4 Rd1 47. Kg2 Rd4 48. Kf3 Rd1 49. a5 Rd8 50. Ke2 Rd4 51. f5 Kg5 52. a6 Kf4 53. Nb6 c4 54. bxc4 1-0 [Dylan Morgan]
