NL 100 (6 max) - T9s

How would you guys play this hand?
Reads: Villain is 20/9 after 75. He seems like a beginner to the game. He has preflop down pretty good, but postflop he is pretty horrendous. His bet sizes are bad. He underbets alot. On C-bets, he was betting less than 1/2 pot alot, even when he had TPTK and there was a flush draw present. Also, him and other guy minraised each other 4 times on one street.
