$100 NL
AK utg, raise to $4, one call from LP

flop comes K73 rainbow. non-threatening board so i half pot it for $5
villain minraises to $10

assume full stacks, and no reads whatsoever
what is the 'standard' play here OOP?
pushing is pretty suicidal cos it could be a 2 pair or a set... for me i have 2 solid choices

a) assume TPTK is good until it's staring me in the face it's not. raise to $20, and then what?

b) play cautiously. call, then check the turn. call down reasonable bets, check the river again if checked through on turn hoping to induce a bluff

probably been done before, but can't find a post directly on point. cheers if you guys can help
