For bet sizing always try to visualize stack vs. pot sizes. In this case you start with a relative stack of $11
On the flop it's $10.5 with a $1 pot.
If you pot the flop then you will go to the turn with a $9.5 relative stack and a $3 pot. That way even a moderate bet on the turn, say $2 will get you to the river with less than a pot size bet left.
In this case I would pot the turn because the board is so draw heavy, but in general you want to pot, or bet closer to the pot on the flop more often, because it will make it easier to get your whole stack in by the river without overbetting any street.

Another situation where you should do this - I'm adding this because I saw something stupid today...
Say you are HU in a dead pot of $5 and $5 stacks with one player already all-in. You hold AA, and the flop is 27T rainbow. There is pretty much no way your opponent is drawing to more than 2 outs, and you want him to commit all his chips. Just remember that you have 3 streets of betting left... you get it... don't blow your load too early. Not really that related, but whateva.
