The Slav, played well, is a fearsome weapon. But I get a lot of wins against it when people play an early ....Bf5, thinking they're developing the bishop. Or even worse and excruciatingly horrible for black, an early ...Bg4.
Your move, good sir (ideally without the engine) -
In most of these slav lines black is outscoring white, often by wide margins.
Regarding the Taimanov, in which move do you play ...a6?
Do you play the slav or semi-slav? And what do you play as white?
Taimanov is a great line. I'm playing 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3 a6
(some poor developer broke the embedded board, otherwise I'd show you)
I usually transpose back into the bastrikov, however against 6. Be3 I play Nf6 and it's more of a pseudo four knights position, which in a few cases can transpose later.
But for the main line - by move 10 black has novelties, it's very underexplored. I haven't had anyone play the sharpest continuation yet, it could change as I climb but... I'm not that worried.
I also find the position is very volatile, small errors often result in pretty radical swings in the eval.
All things I like about it.
