Hero is young asian kid in his 20s sitting on 1500 stack. Playing a pretty TAG game for the most part. Villain has 1000, has been playing with hero for about 4-5 hours. Hasn't been out of line, plays pretty snug, opens a lot of hands in late position, cbets hands that have equity. Not a pro, but not a fish either. Called hero light in a small pot with A9 on QJJ98 board and was good. Most my show down hands have been premium hands. He's on my right and I've 3bet him light 4-5 times in position and he's folded every time (mainly because I think he's opening late position pretty light)
UTG (400) opens $20, MP(1000) calls $20, Villain is in CO (1000) and 3 bets to $60, Hero is on the button with Q
Q
Hero?
I had 2 lines I was thinking of taking:
1. Flat and set-mine because this was CO's first 3bet in 5 hours. His range is super strong. If I 4-bet and get 5-bet I probably have to fold.
2. 4-bet to 170 and see what he does. If UTG ships 400 and CO folds, I'm going to call. If CO 5-bets, I'm folding.
What do you think is the most optimal play?
