I'd also post sample size, call open, and 3bet stats for your next hand, although it's not applicable in this hand. Aggression frequency is better than aggression factor.
$6.50-$7 is good preflop. If your sample is big then make it $7, and keep increasing the size if he keeps calling and then folding the flop/turn and paying off, and you should also 3bet him for thin value(99) as well and no bluffs(76s/A5s/KTo). If you get 4bet then I'd fold, although I haven't done the math on this yet, but villain is too LAP to probably 4bet JJ/QQ/AK.
You can't check-raise all-in here because he'll check behind with too much stuff and may go all-in with a 9 or TT and you can get value/protection from a lot of hands. The SPR is 2.3. Bet $11, he'll call more with stuff. Snap call the shove. Good luck, Yojimgari
