I wouldn't be afraid to almost pot the turn because to villains at the micros 3 or 3.5 is the same bet sizing
but when they get to the river, they'll instinctively want to fold so try to make their stack to be the smallest possible, I think under 1/2 pot is optimal because it's an "unfoldable" stack size

so even if in this hand you bet $1 on the flop, if you bet 3.5 on the turn he's basically paying you off on any river unless he has the flush draw

however, the same applies on the flop, so if you bet just slightly bigger on the flop (say 1.2) you're still getting called by the same range... and we can bet 3.3 which won't even be a psb and then you can shove river and get 100% paid off by a worse ace
