Annotated Game #215: Getting away with a pawn and a win

In this final-round tournament game, after a series of draws, I was looking for a win. The Classical Caro-Kann has been a good opening in terms of scoring wins for me, so I was happy to see my opponent choose it as White. She varies from book with 12. c4, which allows Black to equalize easily. I saw an opportunity to grab White's advanced h-pawn and took it on move 14, which defined the resulting strategic struggle. White could have played more actively, with sufficient compensation for the pawn.

Over time, I am able to consolidate the pawn advantage and make sure that subsequent material exchanges were to my benefit, ending up with a winning double rook endgame. As is common these days, my opponent (a junior) played on until mate. I used to find this practice both annoying and disrespectful, but it seems to be the way competitive chess is now almost universally taught at the scholastic level. Now I just enjoy playing out a winning position (being grateful that I have one) and don't worry about trying to find the absolute quickest path to victory. An easy and safe win is just as good, and it considerably reduces the stress and annoyance factor.

Although I don't quite overdo the pawn-hunting in the opening, it's still enough of a distraction (and detraction) from my game. Seeing in the analysis how White could have taken better advantage of it is instructive. In the future, in a similar situation I would likely play more conventionally rather than chasing the pawn, also bearing in mind the lessons of "Don't Be Greedy in Chess".

White gains compensation for it.} Nxh5 (14... O-O {is the solid alternative.})

rather easily.} (16. Qa3 {would prevent me from castling for the moment and

pawn.} O-O 17. Qc7 Na6 18. Qxb7 Qa5 19. Qxc6 Qxd2 20. Qxa6 Qxb2 $11 {Komodo

development and White has more space, I felt pretty good about my position.
With reduced material available for attack, my opponent did not have enough
compensation for the pawn.} 17. Nd6 {an obvious threat that is easily repelled.

to pressure White's advanced knight than to develop my own first. Komodo
agrees with me, although either option is good. By this point, the pawn
advantage is mostly consolidated.} 19. Ne4 Nd7 20. Rad1 (20. Qg3 $5 {would get
the queen out of the line of fire on the d-file.} Qf5 $17) 20... Ne5 {now my
knight can get into the action, thanks to the pin on the d-pawn.} 21. Qc3 Ng4 {
this is more overtly aggressive, but not as effective for the attack.} (21...

anti-positional to leave the e6 pawn hanging, but White is unable to take
advantage of this.} 25. Qg3 Qxg3 26. Nxg3 Kf7 $17) 24. Qg3 {again pinning the
knight with the positional threat of Qxg6, inflicting doubled g-pawns and
removing the e-pawn's defender. However, I find the solution by protecting the
queen with my king.} Kh7 25. b4 {I thought this was over-optimistic on White's
part.} Nf6 {this forces simplification on the kingside, which works to my
advantage being a pawn up. However, it would be better to immediately target
White's now under-supported queenside pawns.} (25... a5 26. bxa5 Rxa5 27. a3 {
and only now} Nf6 $17) 26. Qxg6+ {this avoids immediate material loss, but
with the queens off the board, achieving a winning position becomes a lot
easier.} (26. Nxf6+ $5 Qxf6 27. Qc7 Kg8 $17) 26... Kxg6 {I had thought
carefully before exposing my king like this. White's reduced material means
that the king position is still solid enough.} 27. Nxf6 Kxf6 {the king's
position is a little unusual, but its more centralized location seems more
like an advantage than a weakness, now that we are in the endgame.} 28. b5 $6 {
this essentially forces a pawn structure change that significantly benefits me.
} (28. Rd3 $5 $17) 28... cxb5 $19 29. cxb5 Rd5 {now White has an isloated
queen pawn that I can effectively blockade and target, while her queenside
pawns also look vulnerable to pressure.} 30. a4 Rc8 {rook activity is the most
important idea. White will no longer be able to cover all of her weaknesses.}
31. f4 {desperation, preparing the next move.} Rc4 32. Re5 {I had anticipated
this and welcomed the further reduction of material. I expect she was hoping I
would exchange on e5.} Rcxd4 (32... Rdxd4 $5 {is what the engine prefers,
which leaves a Black rook in a more commanding position after the exchange.}
33. Rxd4 Rxd4 34. g3 Rxa4 $19) 33. Rxd5 Rxd5 34. Rc1 {naturally not exchanging
again on d5, which would be an obviously won K+P endgame for me.} Rd4 {now it
would do no good for White to place her rook on the 7th rank.} 35. Ra1 Rxf4 36.

kingside pawn and marching my own pawns down the board. White stubbornly holds
out until mate.} 38. Kf3 g5 39. Ke3 h4 40. Rf1+ Kg6 41. gxh4 Rxh4 42. Ra1 f5
