how to play against caro cann defense ?
There is a course for white against the Caro kann with exchange variation
It's a very reliable and practical way to gain the upper hand
Yes @Devansh_Shah is right. But I also suggest that after watching the course then try to work on Carlsbad pawn formation. White gets better Carlsbad in this Caro Kann Exchange Variation. So I strongly suggest to learn Carlsbad ideas if you wanna master caro exchange ideas in depth!!!
