in sizing your bet you should also think about the remaining stack sizes. If the effective remaining stack size is less than say 30% of the pot after the turn bet has been called, then you will have to call the river even when you suspect your opponent has outdrawn you. But on the other hand when your opponent misses he will check fold. So, when sizing a turn bet that you think will get called, if the remaining effective stack size is such that it will be very hard for you to lay down on the river regardless of what card comes because you will be getting such good pot odds, then you should get it all in on the turn.

obviously you should be inclined to bet more if your opponent is a passive calling station and not prone to river bluffs. If your opponent is an aggressive and creative bluffer but doesn't like to call off massive bets with a draw, preferring to sense weakness and outplay opponents, then you would tend to bet less...
