1/2 300cap. Hero has been at the table for a few hours and it's mostly a limpy table filled with typical 1/2 villains. Main Villain on button and covers hero. Folds to him and he makes it 15$. Hero (460$)wakes up in SB with K♠ 9♠ . Hero doesnt know villain but in the past few hours I have seen raise his button a good amount but overall seems like a typical rec player.. I should be doing decent against a reasonable button open. I opt to 3bet to 55 and take the lead, I feel just calling OOP is a mistake... villain calls.
Flop is 110$ and comes K♣ Q♣ 10♠
What does hero do?
