The nine adds a gutter to J8 and JT plus the top two pair for J9. So many better turns for AQ to barrel than this particular one. Take a free card on the turn.
I 3x+ pre and might x back flop, definitely x turn cause AQ has some SDV and he's probably like, "lol .50, I'll ride dirty with 23s for a pack of gum."
I think I 1/3 pot on the flop because this board might be better for our range. OTT I think I’m going to check because that turn card might be better for our opponent and our hand had SD value.
Don't mind the flop bet, perhaps betting slightly less. Checking back the turn as we still have showdown value. The 9 opens up another possible avenue for villain to want to see the river. Betting makes no sense.
