Last time I left you with this position, from a training game in which I had the black pieces against an 8-year-old pupil.
White had just checked on h8, and discovered that after I played Kd7 his queen was unfortunately trapped.
It doesn’t look very interesting, and, but for my tactical incompetence, it wouldn’t have been very interesting. Let’s play on.
30. Qxa8 Nxa8 31. c4 Nxe4
I noticed that the white rook was overworked.
32. Be1 f5 33. cxb5 axb5 34. Ra3 Nb6 35. Ra7 Nc4 36. a4 Qg7
White’s done the right thing so far. If you’re playing in desperation mode you’re not trying to find the objectively best move, but the best way of gaining some sort of counterplay and retaining practical chances. Now, though, he has to defend g2 and has no good options.
After the natural 37. Rc2 Black has lots of winning moves, but the quickest and nicest is Ned2, cutting off the rook’s defence. You might or might not consider this a Novotny Interference: the interference with the rook is deliberate, but the interference with the bishop accidental.
Instead White chose a move which should have lost much more quickly.
37. g3 Nxg3
There was a mate in 5 here: 37.. Rxg3+ 38. Kf1 (or 38. Bxg3 Qxg3+ and mate next move) 38.. Rg1+ 39. Ke2 Qg2+ 40. Kd3 Nb2+ 41. Ke3 f4#. I really should have seen this but automatically captured with the lower value piece.
Never mind: I still have a forced mate.
38. Bxg3 Rxg3+ 39. Kh1 f4
This is mate in 8, but there were two mates in 7: 39.. Qg6, threatening Qe4+ and meeting Re1 with Qc2, and 39.. Rg2, planning Qg3.
40. axb5 f3
Still winning, although it’s not quite so easy now. Here Qg6 was again mate in 7, while Qf7, Qh7 and Qg8 were all mate in 8. I was moving too fast and had completely overlooked the idea of checking on the long diagonal.
41. b6 Qh6
Again Qg8 was more efficient.
42. Rxc7+ Kd8 43. R1xc4
The rook was needed on the back rank. After 43. R7xc4 I have to find some tricky moves: 43.. Rh3 44. R4c2 Ke7 45. b7 Qf4 46. b8Q (46. Rf1 f2 47. Rfxf2 Rxh2+ 48. Kg1 (48. Rxh2 Qf1#) 48.. Rxf2) 46.. Rxh2+ 47. Kg1 Qg3+ 48. Kf1 Rh1# 44.. Ke7 is not at all obvious, I think.
Now I again have mate in 5, but again I missed it. I should have sacrificed my rook: 43… Rg1+ 44. Kxg1 Qe3+ 45. Kh1 Qe1+ 46. Nf1 Qxf1+ 47. Kh2 Qg2#
Playing the queen move first, as I did, should only draw. White now has rook and knight for queen, a lot of checks and a dangerous passed pawn.
43.. Qe3 44. Rc8+ Ke7 45. R4c7+ Kf6 46. Rf8+ Kg6 47. Rg8+
I thought I was winning after this move but had missed an important defensive resource.
Instead, I had to play either Kf6 or Kh6, when White can either take the perpetual check himself or capture on g3, when Black will have no better than a perpetual.
For example: 47.. Kf6 48. Rxg3 Qe1+ 49. Rg1 f2 50. Rf1 Qe4+ 51. Nf3 Qxf3+ 52. Kh2 e4 53. b7 Qf4+ 54. Kh3 Qf3+ 55. Kh2 or 47.. Kh6 48. Rxg3 Qe1+ 49. Rg1 f2 50. Rf1 Qe4+ 51. Nf3 Qxf3+ 52. Kh2 Qf4+ 53. Kg2 Qe4+ 54. Kxf2 Qxh4+.
48. Rxg3 Qe1+ 49. Rg1 f2 50. Rf7+
Not the immediate 50. Rf1 because of 50.. Qe4+ 51. Nf3 Qxf3+ 52. Kh2 Kg4 and Black wins.
White has to force the black king to e4 first.
I still thought I was winning here because I’d overlooked that White could play 51. Rf1. The best I can do is 51.. Kxd5 52. b7 Qxb4 53. R1xf2, but this should be an easy win for White.
Fortunately for me, my pupil missed the idea as well, capturing the queen without pausing for thought. The rest of the game is not interesting.
51. Rxe1+ fxe1Q+ 52. Kg2 Qd2+ 53. Kg3 Qxb4 54. b7 Kxd5 55. Rc7 (Nf3 would have made it harder for me, but he’d lost concentration at the end of a long game and was playing instantly.) e4 56. Nf1 Qb6 57. Ne3+ (A one move oversight, but it only hastened the end.) 57.. Qxe3+ 58. Kg2 Qb6 59. Re7 e3 60. Kf3 Kd4 61. Rd7 d5 62. Re7 Qb2 63. Rf7 Qf2#
Afterwards, as we both had time to spare, he watched as I entered the game into ChessBase. I pressed a button so that he could see the names of famous players who’d played the same opening moves as him. I then pressed another button so that he could see the computer analysis and pick up when one of us made a mistake. Finally, I printed off the game for him (in scoresheet mode) so that he had a complete record. He was amazed at how much you could learn if you recorded your games. I’m not sure how much he learnt, but I learnt a lot from this game. Perhaps I should have been kind to him and offered a draw at the end.
