if you check the flop you risk your hand and the pot. BUT if you check and the turn is a blank being as aggresive as he is he's gonna lead out and bet and you can checkraise him and take it down. if you smooth call your giving him another chance to draw out on you BUT I'm not sure how i would have handled the turn and let me tell you why. he SMOOTH called you. So YES i got trip aces and your like i KNOW hes on that draw so bam you hit the pot only to get raised all in and and the guy has Q-10o lol because hes LAG. So you think youre protecting your hand but in the end paying his hand off. This is such a scary board 88-99-jj Q-10 shoot being a LAG he could have a 10-7s J-9s etc etc etc lol. So really this is a tough board with a LAG. I like what you did but don't worry about protecting your overpair so much as protecting your entire stack. a LAG smooth calling you usually means hes got the nuts because hes not worried about your hand. I used to play LAG style poker and let me tell you what i did...BET at everything but the nuts. I would slowplay the nuts to the fullest to make them think im week and it worked in freerolls and 2NL but the further up the totem poll the more people spot it.

But about your hand i probably would have bet the 3/4ths the pot on the flop because being a LAG hes gonna call if hes on the draw. If the turn doesnt help i'm gonna bet the pot. By only betting 3/4ths the pot on the flop you might be saving yourself money if that scare card comes but your still protecting your pair by your Cbet. It sounds to me like you would know if he hit his miracle so you would be able to fold aces. Some people can't fold aces and treat them like they are a god. lol. I wouldnt over bet the turn like unless i was in a tournament under certain circumstances.
