Annotated Game #348: A familiar trajectory

In this first-round tournament game, my opponent essays the Advance Variation against my Caro-Kann, which these days is considered the most challenging try for White. While I play the opening generally correctly, I over-correct for my normal materialistic bias by postponing capturing the e5 pawn for too long, giving my opponent a strong attack. The trajectory of the game is similar to that of Annotated Game #347, as White dissipates the attacking tension too soon and lets me back in the game, albeit having inflicted some positional damage in the process. I then find a move which flips the game narrative and suddenly my pieces come to life, with a winning advantage. There are some tactics involved and I was glad to be able to calculate correctly the sequence that sealed the victory, which included giving back a piece in exchange for a winning major piece attack.

Nf3 Bg4 {pinning the knight and developing the bishop, which is the point of this variation for Black.} 6. dxc5 {this capture was a little delayed, giving White fewer move-order choices.} e6 {simply preparing to recapture. This line is a (temporary?) gambit for Black, as White can try to hang on to the extra pawn, however at some positional cost.} 7. Be3 {developing and defending c5.} Nge7 {standard knight development and the second most popular move in the database.} (7... a6 $5 {can be played if Black wishes to prevent Bb5 ideas.}) 8. Bd4 {the bishop now protects both c5 and e5, but is mostly limited to its role as a "big pawn"} Qc7 $6 {adding to the pressure on e5, but this leaves White with better options.} (8... Bxf3 {this draws the White queen a bit offside and removes a defender of e5. Combined with the following move, this makes Black's position quite solid.} 9. Qxf3 a6 $11) 9. Nbd2 $14 {now the exchange on f3 would just help White develop.} (9. Bb5 {is also good.}) 9... a6 {this is useful, but a bit late. I am lagging slightly in development and still a pawn down.} 10. Be2 Ng6 {further concentrating my forces against e5.} 11. O-O Be7 12. h3 Bxf3 {the rule in the Advance Caro-Kann is to exchange on f3 whenever there is a choice between that and retreating the bishop. This is both technically accurate and in practical terms helps reduce the amount of calculation required for decision-making.} 13. Nxf3 O-O $6 {this delays the pawn recapture unnecessarily. Black lacks defenders on the kingside, so castling is in fact premature.} (13... Ncxe5 14. Nxe5 Nxe5 15. f4 {this is what dissuaded me from capturing on e5, as the g7 pawn is hanging after the knight retreats. However, the engine is not concerned about this after} Nd7 16. Bxg7 Bxc5+ {the key in-between move, regaining the pawn with check.} 17. Bd4 O-O-O {and White at best has a slight edge.}) 14. Re1 $6 {this looks sensible and eventually will help reinforce e5, but would still allow me to capture there now.} (14. Bd3 $1 {immediately gives White an attack after} Ncxe5 15. Nxe5 Nxe5 16. Bxh7+ Kxh7 17. Qh5+ Kg8 18. Bxe5 Qxc5 19. Qg4 $16) 14... Rae8 $2 {I recall during the game being pleased with my lack of materialism. However, now is the time to regain the pawn.} (14... Ncxe5 $11 {this also usefully covers the d3 square.}) 15. Bd3 $1 $18 {I did not properly understand how threatening this would be.} Nf4 16. Bc2 {preserving the bishop on the key attacking diagonal. Now I am simply a pawn down with no counterplay and White has a good attack brewing.} Na5 {heading for c4, but this will not disrupt White's plans.} 17. b4 Nc4 {the knight looks good, but is not in fact hitting any useful targets.} 18. Qc1 Ng6 {retreating to safety, although stil awkwardly placed.} 19. g3 {usefully controlling both h4 and f4.} f5 {by this point I could see trouble brewing on the kingside and decided (correctly) that an attempt at counterplay was necessary.} (19... f6 $5 {was also a consideration. I chose the text move because it blocked the diagonal, which tempted White into capturing en passant.}) 20. exf6 $6 {White is still a clear pawn up after this capture, but the attack dissipates.} Bxf6 $16 21. Bxg6 hxg6 {I correctly decided that even though the doubled pawns are ugly, they are worth the piece exchanges, as White no longer has an attack. However, my opponent does not recognize this and over-presses with} 22. Ng5 $2 e5 $1 $19 {suddenly Black is winning, with central pawn dominance and fully activated pieces.} 23. Be3 e4 {opening up diagonals for both the bishop and queen, while taking away the f3 square from White's knight.} 24. Qd1 {although my weakness on d5 is targeted, this also leaves the Ng5 under-protected, so I decided to go for winning material immediately.} Nxe3 (24... Qd7 {is a better version of the idea, defending d5 first. Although the Ng5 can be reinforced, which I saw, White has too many other weaknesses.} 25. h4 Bxc3 $1 $19) 25. Rxe3 Bxg5 26. Qxd5+ Qf7 $1 {the only move, as the Bg5 is hanging; I saw this sequence as part of the calculations for move 24. If White chooses to take the bishop, as he does in the game, I correctly calculated that Black has a winning attack afterwards due to the f2 weakness. I would also be happy entering an endgame after an exchange of queens on f7.} 27. Qxg5 {probably the correct practical decision, forcing me to prove things tactically.} Qxf2+ 28. Kh1 Qd2 {pinning the Re3 against the Qg5 and preparing to play ...Rf2.} (28... Rd8 {is even better, but the text move is winning.}) 29. Qxg6 {an unexpected way out of White' pin. Now I simply take the rook and follow a conservative strategy of trading down to a winning endgame while not blundering, rather than trying to win as quickly as possible.} Qxe3 30. h4 Qxc3 31. Rg1 Qf3+ 32. Rg2 Qf5 {essentially forcing the queen trade.} 33. Qxf5 Rxf5 34. Re2 e3 35. Kg2 Kf7 36. g4 Rf6 37. Kg3 b6 38. g5 Rc6 39. cxb6 Rxb6 40. a3 Rb5 41. Kf3 Rf5+ 42. Kg3 Kg6 43. a4 Kf7 {obliging White to do something further weakening on his move.} 44. b5 axb5 45. axb5 Rxb5 46. Kf4 Rb4+ {and my opponent sensibly resigns.} 0-1
