Easy River value Bet?

Villan was pretty much a standard 10/20 45/20 ish lag. I hadnt seen anyting out of the ordinary from him yet. Am I ahead of more then 50% of the hands hs calls with here?

I can definitely see players calling here with A high here. A PP 9s and up would have bet, as would any K hand. So, will he call you with more A highs than A7s that beat you? Yeah, I think he will.

I generally dont think that with a loose LAG in the blinds riasing 87o on a steal is a good plan PF.

Flop on turn, Id like to put a raise in there somwhere, but it all depends on how LAG he is. If hes big LAG, then you are prolly just better off calling down, as he will 3 bet from behind to often to allow you to fold to a 3 bet. If he isnt crazy lag, then I want to raise so he quits the hand and doesnt hit one of his overs.

As for the river, I think its really thin, but I think there is value here, hes prolly the type that will call with A high, and cerntainly if he has a lower PP (which is effectively the same thing from his standpoint, altho they never realize this). I think a nine fires at you again, so your only real worry is a 7 with a bigger kicker.

I normally dont raise this, but the bb was like an 18/12 guy thats why i didnt question the pf raise.
Given this with a lag in the SB and a tight BB would you still fold it preflop?
I was alread pretty tight playing the 5/10 and with the increased PF agression in this game I have not been playing enough hands. So I may have been overcompensating.
