the fact hes good means we should fold even more pre
I really don't think you can just say 'he's good don't play him' at 100nl and expect to improve much
Just because he has a positive winrate doesn't mean that he isn't exploitable, you're just going to have to make adjustments in areas that you're not used to if you're never playing winning regs. His leaks aren't going to be as blindingly obvious as they will be vs a fish but they are there and can be exploited.
If he cbets too much - this is exploitable
If he double barrels too much - this is exploitable
If he raises 100% pre and doesn't peel 3bets enough - exploitable for an immediate profit pre
If he raises 100% pre and peels too many 3bets - this is exploitable
You can peel a TON more hands than conventional wisdom says you can vs guys that are too aggro on flops if you're going to play against it correctly.
