I'm a 1800 Elo player that likes positional, quiet, drawish, slow, boring and strategic openings.
As Black against 1. e4 I play the Caro-Kann. But there is one variation of the Caro-Kann that I slightly dislike: the Advance Shirov (4. Nc3).
[StartPly "7"] [FEN ""] 1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nc3 e6 (4... Qb6) (4... h5) (4... a6) 5. g4 Bg6 6. Nge2 (6... f6) (6...h6) (6... Ne7) (6... Bb4) (6... Nd7) (6... Be7) c5 7. h4 h5 (7... h6) (7...cxd4) 8. Nf4 Bh7 (8... Nc6) 9. Nxh5 cxd4 (9...Nc6)
It seems to be much more sharp, aggressive, chaotic, wild and tactical than every other variation of the Caro-Kann. And so I don't know what to play against it.
I could go for the main line with 4... e6 5. g4 Bg6 6. Nge2, but then I don't even know which variation to choose next among all the available options.
Or I could choose to stop 5. g4 with 4... Qb6, 4... h5 or 4... a6, but I don't even know if any of these three moves are objectively good.
I've included everything in the FEN diagram.
And so my question is: which variation tends to lead on average to the most positional, solid, safe, quiet, drawish, slow, boring and strategic positions? (i.e. the least sharp and tactical positions)
But note that the variation also needs to be objectively good and reliable. And if possible it needs to be played reasonably often by Grandmasters. I don't want to play something bad just for the sake of not entering into complications. (i.e. I would still prefer something that is both tactical and good over something that is both positional and bad.)
