Digging through the vault

Fall is upon us, and with it shorter days and less time spent outside.  To reinvigorate myself after a lengthy absence from chess, I've decided to go back through my old tournament games, partly for nostalgia but mostly to learn some lessons.  Those who do not learn history being doomed to repeat it, etc, etc.  Fortunately, there's ~300 tournament games I analyzed over the last 5 years or so, which means no end to the fun.  Let's start with #1, back in 2008, in a Westfield Quad against the venerable Leonid Fleysher.  We had an odd history, where Black won most of the games we played, and usually only after being in a lost position.  If I remember our lifetime record was something like 3-4-3, which means the decisive game is yet to be played....

Leonid Fleysher (1947) - Ian Mangion (1796), Sep 14 2008, Westfield, NJ

1. c4    Nf6
2. Nf3  c5
3. Nc3  e6
4. g3   b6
5. Bg2  Bb7
6. O-O  d6
7. d3   g6
8. e4   Bg7
9. a3   a6
10. Rb1  Nc6




Black has offered to play a Queen's Indian, White prefers to play a Botvinnik system English opening.  With his last moves White is preparing the thematic b2-b4, which to my ignorant mind is key to the system.  With the center virtually locked, breaks on the flank are not only reasonable but necessary.  If White delays, Black can prepare ....b7-b5 with the same ideas.

11. b4  O-O    (a minor inaccuracy with dour consequences.  Now  12. bxc5  dxc5 13. Bg5  Qc7  14. Bf4 leads to an awkward position, which incidentally is basically seen later in the game.   11....Nd7 is stronger, hitting the knight on c3 and allowing recapture on c5 with the knight on d7)

12. Bg5 Qc7
13. Qd2 Nd4
14. bxc5






14....   Nxf3+ ?!     (hard to imagine what compelled me to play this.  these days I would play ...bxc5 almost without thinking.  perhaps I was trying to simplify, but really Black's knight is better)
15. Bxf3  dxc5        (now ...bxc5 can be met by the vexing  16. Bxf6!  Bxf6  17. e5!)
16. Bf4    e5        
17. Be3   Nd7     
18. Nd5


Now Black's position is unpleasant, to say the least.  His only active play can come from breaks on the b or f-file, but with White's dominance in the center, such play is likely to end poorly.  My mind already drifted toward defeat at this point.

18......  Bxd5
19. exd5  Qd6
20. Bh6 ?!  Rab8
21. Bxg7   Kxg7
22. a4      Rb7        


White made the curious decision to get rid of his bishop pair, exchanging his 'good' bishop for Black's lemon on g7.  White's protected passed pawn on d5 promises an advantage, but now Black has latched on to a clear strategy of cracking open the b-file.  ...f5 could follow as well

23. a5?  Rfb8?  

Favors for favors.  23. Rb2 was much stronger, preparing to oppose Black's doubled rooks with his own doubled rooks.  But then Black misses the big chance - ....b5!  For what else was he putting his rooks on this file?  Surely not just to trade them off, endgames for Black promise passive defense.  

24. axb6  Rxb6  
25. Ra1?!  Rb2    

Why does White avoid the trade of rooks?  Only Black can benefit from tactical continuations.  Now Black dreams of doubling his rooks on the 7th rank.  Remarkably, he even manages to achieve this, albeit with some help.  White's position is still preferable, but he has opened up the possibility of all three results.


26. Qe3  f6 (...f5!?)
27. h4   h5
28. Kg2  Rc2?   (dreaming of doubling the rooks, but White cleverly latches onto the chance to awaken his dead bishop)
29. Bd1!  Rcb2
30. Ba4    Nf8

Ugh.  ...Nf8 was forced, both tactically (the a-pawn) but also positionally - the position with queens and rooks only must be a win for White.  As it is, with his bishop outside the pawn chain and terrorizing Black's back ranks, White has a decisive positional advantage.


31.  Bc6  R8b6
32.  Ra5?

I was in time trouble by this point, and this on the rickety old wind-up clocks once so prevalent at Westfield.  However, by good fortune I had stayed awake to tactical possibilities - after all, this is all I could hope for.  How could I get my knight back in the game?

32. ....  Ne6!

Exposing the subtle fault in the bishop laced on c6 - it is defended only by the passed pawn on d5!  That pawn can now take my knight, but....at the price of the bishop, and then its own life.  White still has a reasonable position, but Black now has active threats, and the sudden change in the momentum provoked my opponent into further mistakes.  A common phenomenon!

33.  Rfa1   Nd4  (remarkably, a Black knight once again sits on d4, as part of its journey from g8-f6-d7-f8-e6-d4)
34. Ba4 ??  Re2!   (even more remarkably, Black achieves his long held dream of doubling his rooks on the 7th rank.  This is one bridge too far for White.  Despite my time trouble, I smashed White's position with poise that was very rare for me at that time)

35. Qc1  Rbb2
36. Qf1  Nf5
37. Kf3  


37. .....  e4+!  
38.  dxe3  Re3+!   (I had my Wheaties that morning, clearly)
39. fxe3?!  Qxg3 mate

And so....a game played with indifferent skill by Black, saved only by a remote tactical opportunity in what should have been a lost position.  Such is amateur chess!  But we'll see many, many examples where I'm on the receiving end of bad fortune.
