Triangle Slav

Sort:
playchessordie19
So I have started taking up the Triangle Variation of the Slav defense as a means of trying to eliminate the problems of having to bolster c6 and defend the dark squares around it. Are there any traps that Black has to be aware of in the opening and what are the counters to them? Also, are there any decent tactical chances that Black can exploit for advantage going into the middle game? I will post two games from a daily chess tournament in which I played the opening from both sides in a couple days

I would like to see the games. Thanks

I'll probably pay them tomorrow or Monday. They were a bit wild.

I told you that :)

Here is the first game where I had the White pieces and launched an early middlegame attack after diverting the f6 Knight away from the King's defense. The final 10 moves were not especially easy for me to find, especially after the Nxd7 move.

Do you have a premium level of membership for chess.com? You can analyze your games live. Otherwise, download a PGN file of your game and use a chess engine to analyze the game on your computer.

The chess.com engine is saying that you should have done 12. Bxh7+ instead of 12. Nxd5. After 12. Nxd5 exd5, black's c8 bishop can reach f5 to defend h7.

It seems to me black wasted a move or two with the f8 bishop. The Meran/Anti-Meran variation here usually has black play 5...Nbd7. The engine is saying however black is not doing too badly until 8...a6 which as you said gave you a development advantage.

I do and I looked at the review a bit but did not get too much into the analysis lines as these are a couple of the first games I have played in this opening. For the post mortem, I pretty much just looked over what Stockfish said at about a 24 depth but over the next few days I'm going to look more closely and see if there are ways to improve the way I handle the game

I played the triangle slav with black as my main opening for a while. I bounced between this and the mainline slav for a while and for the last few years, switched to playing the semi-slav. The triangle variation isn't too bad, but you can quickly fall behind in piece development if you aren't careful and that's why the earlier ...Nf6 of the mainline is preferred to pushing several pawns so early.

If you use the triangle slav, the only variation I find worth playing is the noteboom variation with ...dxc4 and some sharp play, but this also runs the risk of falling behind in development if not careful. My positions were okay, but I eventually switched to more mainlines because of this lack of development.

In both games, we played dxc4 but in the second game, I opted for piece development over space figuring to look at simplifying when able to. My main idea to try to learn this was to try to find ways to negate the weak square issue around c6 and this looks to have mixed results.

So I looked at the review and Stockfish and both show that 9... Bb4 was wrong, suggesting either 9... c5 or 9... Be7. Also, the sac was bad after Nxd5. Instead I should hit h7 before the Knight exchange and the follow up is actually with Ng5+ instead of Qd3+.

You are confusing the Semi-Slav with the Triangle defence (where ...Nf6 is usually delayed for quite a few moves).

Delaying ...Nf6 avoids the sharp and highly theoretical Botvinnik/Moscow variations, and allows the Marshall gambit.

Thanks. I think part of it is that the explorer feature for some reason was identifying the opening as the triangle variation
