MW pot- It's all kicking off on the turn and I have the third nuts.

Villain in this hand is a reg who is new to this pool. I have no relevant information on him aside from this.

Villain opens to $1.50 in the HJ, CO calls, BTN folds, SB calls and Hero calls with 9♥8♥ in the BB.

Flop ($6.00) T♦7♠J♣ SB checks, Hero checks, HJ checks, CO checks.

Turn ($6.00) K♦ SB bets $3.00, Hero raises to $9.00, HJ raises to $19.00, CO folds, SB folds, Hero??
