Hulse-Mangion, USATE 2008

Some backdrop:   I was rated 1700 at that time, and I had just been playing tournament chess after a 12 year layoff for six months.  I owned two books on opening, one of which I had read, and the other I was carrying with me at the USATE, Starting Out: The Nimzo-Indian.  Coming into round 5 our team was doing pretty well, so we were playing up that round, and I knew I would have Black against a tough player.  So I tried cramming a few Nimzo-Indian lines in the hour before the game, my strategy against 1. e4 having been decided - hope and pray.  Coincidentally, I had been playing an email game with an old friend, and it was a Queen's Indian Defence, so I thought I would have a good shot of being able to play something reasonable against 1. d4.   My opponent showed up, asked my rating, and without being prompted told me he was a master (I don't ask because I have an odd tendency to let someone's rating affect my decisions.  However, against higher rated players who tell me their unsolicited ratings, I have a 1-0-2 record, so keep it up guys).   Now to business:

1. d4 (sigh of relief) Nf6  2. Nf3 e6 3. c4 b6

Time for a Queen's Indian - I had to hope my opponent would play 
into the only line I knew and hang on from
 there.  As it happened, he did...

4. g3 Ba6  5. b3 Bb4+ 6. Bd2 Be7  (This odd check and retreat is from theory, where the general idea is that White's bishop is better plac
ed on b2 and Bb4+ disrupts normal development)

7. Bg2  O-O 8. Ne5 c6 9. O-O d5 10. Bc3


In a roundabout way we've reached a standard QID position, where theory recommends ...Nfd7.  However, we had gone past my meager opening knowledge, so the games begin...

10....dxc4?   Ugh.  There goes my foothold in the center.  From now until the end of the game there is one overriding theme - White's space advantage and better mobility, and how he tries to exploit this.  Not pleasant to endure 
in long time control
...

11. bxc4 Qc7  12. Nd2 Bb7 13. e4 Nbd7


I'm glancing at computer analysis while writing this, but nothing dramatic is going on.  White is simply better.  Compare this diagram to the last and you can see the consequences of poor pawn exchanges - White has several comparable ways to increase the pressure while Black can only hope to exchange pieces and free his game.  

14. NxN?!  (Black is one pair of pieces closer to equality) NxN  15. a4 (searching for a new weakness on b6) a5!? 

The computer doesn't like this move nearly
 as much as ...e5! which it claims leads to equality.  Very non-intuitive for me, but in essence White does not gain from trying to create a passed pawn with 16. d5 because Black is not obliged to exchange but can simply blockade.  While ...a5 may not be the best, I did a rough calculation and convinced myself White could not win the b6 pawn.  This could be true, although a deeper look may question whether defending the b6 pawn should expose me to attacks on the kingside because of White's mobility advantage.  Isn't chess complicated?

 16. Rb1 Ra7 17. f4 Bb4!?  
A move I was proud of at the time - I'm prepared to sacrifice a pawn to get Benko gambit-style compensation by pressure down the a- and b-files.  The computer doesn't object yet...

18. Qb3 BxB 19. QxB Ba6

I was surprised my opponent let me exchange another pair of pieces...and yet I may have been better to keep the bishop, as my dark square weaknesses became a problem.
 
20. Rfc1 Rc8 21. Bf1 Rb7?!  Focused only on Q-side counterplay, I missed...
22. e5!     Now d6 is perilously weak, a perfect destination for the White knight (which incidentally is threatening a fork of my rooks).  Oh, for a dark squared bishop.

22...Rb7  23. Ne4 Rd8 24. Rd1     White's advantage has become concrete - I felt my only chance would be to somehow induce a knight exchange on d6 by the circuit Nd7-f8-g6-e7-c8.  Remarkably, my opponent fell into this, and only this let me survive.

 24....Nf8 (the journey begins) 25. Nd6 Ng6 26. Bd3 Ne7 27. Be4 Nc8 28. NxN?

In my notations I rated Be4 as the key mistake, because it cut off the knight's escape from d6.  But now the computer points out 29. c5! makes the knight untouchable, as taking it creates a deadly passer.   However, my opponent seemed surprised by the acrobatics of my knight, and missed the best chance.  Now I'm climbing
 back into contention, and another pair of pieces is off.

28...RdxN  29. f5 b5?! (not a good move perhaps, but I needed counterplay psychologically)
30. fxe fxe   31. cxb cxb 32. Qd3 (A fine move I missed, winning a pawn) Qc4 33. Bxh7+ Kh8 34. PxP BxP  35. QxQ BxQ
An endgame has arisen that only White can truly hope to win.  However, doing so will not necessarily be easy with his extra pawn being backward and Black having an outside passer.  

36. Bc2 Bd5 37. RxR RxR 38. Ra1 Rc8? (better is ...b2, seeking activity for the rook and maintaining the balance) 39. Bg6 Ra8 40. Bc2?! Rc8   Draw agreed on White's request.  1/2-1/2

Despite the fact that the teams were tied, I think my opponent was a bit disappointed and exhausted, the game now being 4 hours old.  I think if he were better rested he would have found a way to squeeze me and improve has advantage to decisive proportions.  As it was, I was proud of myself for holding up under the drawn out pressure of this game, which gave me hope that better games were to come.
