Hand I think I played well

[MRBAA]

Vehn, think back to low limits and players who play many hands and make MANY more calling errors than folding errors. They will (and did) call you to the river with any hope at all. You will rarely be able to win uncalled. Given that there are three other players, and he only has fives, do you still think a flop bet in this type of game (where there is little semi-bluff value) is worthwhile?
