200 hands, batshit crazy pre, 43% and 40% 3b vs CO and BU, 28 sample on it.

Was 3b nonstop from the blinds. but Post flop af, low, and cb 36%

Vs this type of player, i would check this flop in position,

Way behind or slightly ahead, just fold now unless you got some read on him that range on this flop is heavily skewed to draws

And I agree with Pb here, this is a decent hand to check back in position.

To profitably call here you need to win over 65% of the time.

It's unlikely you will get exploited here bet/folding to a shove, you have strong hands in your range that gain massive EV if he's doing this too light too often.

Tighten up pre, 4bet lighter, and call IP lighter, to some degree.

I usually flat the 3bet pre but I guess this guy was crazy enough you were happily 4b/getting in even 180bb deep? He just snap 3b/shoving all lower pairs and suited aces etc

This is a flat, don't see why 4bet this especially if he'll let you realize your equity postflop.
