I mean he isos weak bets weak 3way
shouldnt stand much pressure right?
and I shouldnt expect to bluff very much at all here with the fish behind me

i think i rather just call flop

it would kinda suck to get it in, and we also want the 3rd player to call esp if he has a random hand like K5s or whatever

we also can't rep KK or TT so our value range is just KT and 22, maybe K2s

You prob don't need a raising range here, flatting with everything you continue with (plus there's a fish to come along for extra value) will let you do a lot of stuff on the turn anyway, regardless if he bets again on the turn or c/f, c/c. (He'll prob end up giving up more often with his air/marginals anyways because your call in the middle is unlikely to be air). Even if your third assumption of how the villain views this raise is correct - and the play is profitable, it is still probably not as profitable a line to take than to just call (especially since the fish can actually have a strong hand here and reraise you here - or the villain just has KT, AK, KK, TT, AQs etc etc).

Def flat flop
