I do this on the turn;

say I bet pot on flop 57J when I have 89TQ, and get one caller (assume that a flush draw is out). Then the turn pairs the 7. Now I bet 1/2 pot: betting full pot would not represent the boat quite well, since with the boat I want value and not scare away a draw. If they still call then I may fire another 1/3-1/2 pot bet on the river depending on whether I think the opponent can let go of his hand. The 1/2 pot here on the turn is good because you don't intend to call a raise anyway.
Occasionally I get burned playing this way if I don't read my opponent well enough and he is being very passive with bottom set or something, but this works surprisingly often. Of course, you have to make the same type of bet when you actually fill up on the turn...

Your 88K example is different I think. Here I typically either bet pot or I check the flop, since many opponents either see a smaller bet as weakness and will raise you off your hand (you want a cheap showdown here) or they get confused into calling, and that doesn't give you any information for next streets. I guess stack sizes and position guide my play here...
