Annotated Game #293: Follow the needs of the position

This next first-round tournament game is instructive for how both sides fail to truly follow the needs of the position. As White, I fail to exchange off the Black knight on e4 early on in the best way, which leads to major cramping and a winning advantage for my opponent. However, later on he exchanges off his double rooks, which were dominating the position, and allows me to escape into an opposite-colored bishop endgame. Both were mis-evaluations of the position, ultimately, and what was required in it.

Ndf3 $6 (10. Nxe4 {is more consistent with the needs of the position. White will need to trade on e4 at some point and if the bishop capture there is delayed, the knight capture then makes the most sense.} fxe4 11. Be2 $11) 10... Bd7 {developing rather than increasing central pressure.} 11. Bd2 $6 {this gives Black too much leeway in the center and is too slow.} (11. c4 $5 {looks messy, but is more active and leverages the presence of the Bd3.}) 11... Nxe5 $17 12. Nxe5 Bxe5 13. dxe5 Qb6 {after the central exchanges, White is left with less active pieces and Black can freely develop with additional pressure.} 14. Bxe4 {late in coming.} dxe4 15. Qb3 {naturally hoping for an exchange, to help ease the pressure on my position.} (15. c4 $5 {playing for activity, as otherwise the Bd2 is worthless. I recall considering the move, but did not look at it hard enough.} Qxb2 $2 {does not work due to} 16. Ba5 Qa3 17. Qxd7 Qxa5 18. Qxe6+ $16) 15... c4 {this is a good way of restricting c3-c4, but the queen exchange is still a net benefit for me.} 16. Qxb6 (16. Qxc4 $2 Bb5) 16... axb6 17. b3 $6 {Be1-h4 is a better idea for getting the bishop active.} Bb5 18. b4 $2 {the wrong pawn advance.} (18. a4 Bc6 19. Rfb1 $15) 18... Rfd8 $19 19. Rf2 {this finally gets the rook playing, although to a small degree.} Rd3 {Black has a straightforward plan, which is to exploit his space advantage and the open d-file and half-open a-file. His rooks are mobile, which is a large part of the advantage.} 20. Kf1 Ra3 {an unusual bind on the 3rd rank. While Black is still considerably winning, this starts to restrict his pieces as well, however.} 21. Re2 Ba4 {my opponent correctly deduces he needs to bring in the bishop as well.} 22. Be1 Be8 {evidently seeing less progress on the queenside for it, he prepares to shift the bishop to the kingside.} 23. Kf2 h6 {a correct waiting move, which also prepares ...g5. My passive defense cannot reasonably be improved upon, while Black can improve his position.} 24. Rc2 g5 25. g3 Ra8 $6 26. Rb2 $2 {still concentrating on more passive defense, although with the next move played in mind.} (26. a4 $1 {again, the idea of a freeing pawn sacrifice.} Bxa4 27. b5 $1 {Now the pin on the a-file makes things very awkward for Black.} Ra5 28. Rca2 Bxb5 29. Rxa5 bxa5 30. Rxa5 Bc6 $17 {Black is a pawn up, but White's chances are much better with the active rook.}) 26... Kf7 $6 {centralizing the king is a good idea, but this allows} 27. b5 {finally playing somewhat actively, in this case to restrict Black's bishop, although the pawn is exposed here.} Rd5 28. Rab1 Ra5 29. Kg1 $6 {this was more the result of hallucinatory threats on my 2nd rank.} (29. Rc2 Bxb5 30. Rb4 {is at least somewhat more active.}) 29... Raxb5 $6 {this allows me to exchange off a pair of rooks, which is normally better for the defender who is under pressure.} 30. Rxb5 Rxb5 $6 {and now we reach an opposite-colored bishop endgame, which is entirely drawable.} (30... Bxb5 $17) 31. Rb4 $6 {better to immediately exchange.} (31. Rxb5 Bxb5 $11) 31... Rxb4 {thankfully, my opponent continues down the same road.} (31... Ra5 32. Rxb6 Rxa2 (32... Ra7 33. Rb4 Bc6 34. Rb2 $17 {leaves Black in more active shape, although with the opposite-colored bishops it's probably still drawn.}) 33.

Kd2 Kg6 {my opponent apparently still thinks he has chances to break through on the kingside.} 36. h3 Kf7 (36... gxf4 37. gxf4 {and the Be1 covers the h4 square, preventing the Black king's entry.}) 37. Kc3 b5 {this essentially admits that the game is drawn.} 38. Kd2 gxf4 39. gxf4 Ke7 40. Bh4+ {still drawn, but now I get to have some more active fun with my piece first.} Kd7 41.
