4 bet much larger preflop. The weak 4 bet just invites LAGs to play those types of suited hands. Assuming it's 400NL and my math is not wrong, he just has to call $56 into a pot $150. LAGs will call with suited gappers.
I would have made it AT LEAST $150. I am looking to stack off so I wanna build the pot as big as possible preflop. I also don't wanna give the LAG good pot odds
to play speculative shit. Plus there's a third player (UTG) in the pot. Considering the UTG raise, there's a good chance he will call or come over the top.
Being OOP with just an overpair vs. a guy who would play ATC is tough. You're never gonna fold except on the scariest of boards so that sets you up for failure.
Also, the flop bet is too small. Punish these mofos. They'll still get you sometimes when luck goes against you, but you should be punishing them for playing too many hands when you have the goods.
