Annotated Game #342: A first 'true' Dutch Defense as Black

This third-round game saw me bravely use the 'true' or 'pure' Dutch Defense (1.d4 f5) for the first time as Black. I've previously played the Dutch Stonewall by transposition, but decided to adopt the move one version so I can use the Leningrad Variation. My opponent was rather hesitant during the first few moves, which indicated to me that he was not familiar with the Dutch at all. That said, he played into the main fianchetto line for White with the rare 4. f4!? thrown in, apparently in an effort to play symmetrically and reduce the chances of any surprises. As a result I equalized rather easily, but then blew the middlegame with some poor choices, including misunderstanding the best way of contesting the a-file. That has happened before in my games, so I hope I've learned my lesson there. The Dutch performed well in the opening phase, however, so the loss was not its fault; I'll need to do better by it in the future.

Bg2 g6 {so far we are heading for the Leningrad Dutch main line, but now White deviates with the rare} 4. f4 $5 Bg7 {there is no reason Black should not continue with his development plan.} 5. Nf3 O-O 6. O-O d6 {Black has won all three database games I have from this position. With the text move, I continue to follow the main line Leningrad plan, contesting e5.} (6... e6 $5 {controls d5 but leaves Black's further development flexible.}) (6... d5 {is the engine's preference, establishing a symmetrical structure.}) 7. c4 c6 {continuing with the main line Leningrad idea of contesting the d5 square.} 8. Nc3 {by transposition, we have reached a somewhat more common position.} Na6 {is a common development idea for the knight, with ...Rb8, ...Nb4 and ..a5 as ideas for follow-up.} (8... Nbd7 {is more solid and scores better, fighting directly for the center.}) 9. a3 Bd7 (9... Nc7 {played immediately is probably better, as the knight now has no future on a6.}) 10. Qd3 Nc7 {both sides are equally developed and the position is dynamically balanced overall.} 11. Bd2 Rb8 (11... a5 $5 {would directly contest White's obvious plan of advancing his queensidde pawns.}) 12. b4 b5 $11 {Black is now fully equalized. With the rook off of the long diagonal and thus not a target for a discovered attack, this advance is possible.} 13. c5 {now there are multiple good options, but it was not clear to me what the best plan was.} Ncd5 {not bad, but perhaps not best.} (13... Be6 $5 {with the idea of occupying c4 as an outpost for the bishop.}) (13... a6) (13... Rc8) 14. Rae1 {it is a bit premature to commit the rook like this.} Nxc3 {the best move, according to the engine. My knight previously sitting on c7 exchanges itself for its better-placed counterpart, while leaving behind more space for my pieces to maneuver.} 15. Bxc3 Qc7 {connecting the rooks and influencing the center more with the queen's presence.} 16. Nd2 d5 $6 {I had a long think here about changing the nature of the position, in this case to a more closed one; however, the engine prefers not to lock things up.} (16... Be6 $11) 17. Ra1 $14 {correctly moving the rook back to the more dynamic queenside for White.} a6 18. a4 {White is now able to focus his resources on the a-pawn lever, without having to worry about his center being exchanged/dissolved.} Ra8 $6 {wrong idea - how about that a-file (again)? Black does not need to occupy the a-file to shut off White's use of it.} (18... Ne4 $14 {better to gain some minor piece activity.}) 19. Ra2 Ra7 {not realizing the looming difficulty on the a-file.} 20. Rfa1 Rfa8 21. Nf3 $16 {White is now clearly better, with his pieces more active and me having to worry about potential tactics down the a-file.} Ne4 22. Be1 {preserving the bishop, which is helping restrain any potential movement by my queenside forces.} Bf6 {played as a waiting move. Unfortunately I have little that I can do to improve my position.} 23. e3 Kg7 24. Nd2 Nxd2 $6 {I did not properly evaluate the consequences of the piece trade.} (24... a5 $5 {no pawn lever, no plan. With the knight temporarily obscuring the Be1, now was the time to try this.} 25. axb5 cxb5 $14 {now White has much less pressure and I have hopes of getting in a5-a4.}) 25. Bxd2 $16 {I thought I could hold a draw with a closed position and the knights off the board, although defending the a-file remained a nuisance. Unfortunately White still has all the pressure and winning potential.} h6 (25... e6 $5 {the engine rates as equivalent, but it would prevent the tactical trick for White that soon appears.}) 26. Qa3 bxa4 $6 {this opens things up to White's advantage.} 27. Qxa4 Bc8 {this is passive defense, but I have no good options anyway.} 28. Qa5 Qxa5 29. Rxa5 Kf7 $4 {I was starting to feel some time pressure here, but in any case missed White's next.} (29... e6 $16) 30. b5 $1 cxb5 31. Bxd5+ $1 $18 1-0
