Is iso raise proper? When I iso raise, I use wider range if fish folds > 50% to cbets (this guy 56%) so I can play it profitable also when I miss the board, and stronger hands when fish is calling station.

When he shoves, I put him on fd, also Jx, maybe overcards, so I guess I a doing fine versus his range given the dead money.
