Given your read on this guy I like the line but would prefer a call on the river. Your description of him basically means he's not thinking about poker in the same way as most on this forum think about poker. I think it's easy to find a 10% of the time random hand (including worse As) you beat. And ****, you've only been there for 15 min. Don't be the guy that starts out by showing the table you're a bet-folder on the river :P
My opinion is this board texture isn't one this dude is gonna have a bluff raise on, what bluff raise bets the turn? And loose passive guys arent value raising worse. I am not trying to play GTO in live 20/40 vs a loose passive fish.
The hand is fine on early streets just cuz we got a crummy run out doesn't mean we can go back and claim the hand isn't worth playing.
