Hello there.

I watched a video in which the coach said that when someone is overcalling our 3bets, we want to 3bet more linear.

Then he said that when we 3bet linear, we want to lower our sizing because it is more appropriate from a theoretical perspective.

What i dont understand is: if we lower our 3bet size and our opponent calls the same range, he's making a smaller mistake or no mistake at all by overcalling it. Wouldn't it be better to 3bet big and linear from an exploitative perspective ?
