It is a 1/2 home game but stacks are deep (300~400 BB).
It is live straddle for $5. UTG+1 and UTG+2 limp and hero raises to $25 from MP1 with A♦ T♦. Everyone to the button folds. Villain on SB who is a very nitty player cold calls with a serious face.
UTG who had made the straddle and UTG+1 and UTG+2 call. so it is 5 way to the flop.
pot is (5X25=$125), flop 3♠ 5♠ T ♠,
It is checked to hero and he bets $60, the nitty sb calls and everyone else fold, it is heads up.
pot($245), turn Q ♣ ,
Villain tanks and checks.
What hero should do now? is it a bet or check back against the tight preflop and flop calling range of a very nitty player?
