2/5 BigO, 6 or 7-handed, $800 effective, relatively early in last night's session. Button (pretty tight, thinking player, not overly aggressive, mostly a NL player, but plays in our Omaha mixed game often, has some experience) straddles to $10. MP (loose passive) limps, I pot to $50 with a trashy hand A♠ A♦ J♣ 8♣ 7♠ for fun, knowing that I'm almost NEVER getting 3-bet here and planning to hit it pretty hard or just fold many flops. Button calls, MP calls, pot is $150.
Flop is A♥ A♣ J♠
MP checks, I check, hoping to get an action type turn card to allow people to put money in the pot. Button (somewhat surprisingly) bets $75. MP folds. I give the button air (like 24577 or some other low hand along those lines) almost all the time here, so I just flat. There's a possibility obviously that he has JJ, but I block a J, so I think combinations wise that's unlikely.
Turn is 8♠
What is the correct thought process here assuming my range for villain is accurate? Do I want to lead for pot on the turn, denying button the opportunity to draw to 20+ outs for a low or charging him the max if he decides to call? Do I want to bet something like half-pot and hope for a call with a 23xxx type of hand to get value and risk losing half the pot on the river?
Thanks for your advice.
