I would bet much bigger on every street. As played fold I guess.

Ass dry flop, like the bet sizing.

I probably call just because I almost never fold Aces, but it's probably a fold.

ive been calling to many of these hands lately at 200nl and they never seem to be bluffs.

I think it's a trivial fold and 44/66 often

I'm in the bet bggger camp, especially on the flop and turn. Dry board yadda yadda but if he has 99 he's not going to suddenly call 3 streets because you knocked a few dollars off your bets on each street. If he has Qx he decides on the flop how many streets he's gonna see and he wont re-evaluate adequately based on your betsizes.

Fold river unless you think he's special and I love his line with JJ/67cc etc.
