Advanced Theory: Winning a half bet

Ok here she is. Your at a limit table, 6 handed. 3 fold, your heads up with AJ. The flop comes KJ4. BB bets, you raise, he calls, turn blank card, he checks you bet, river another blank he checks you check. At a limit table you just saved yourself a half bet!!! Since u checked the Riv but raised the turn, you did 3 things, first...saved a half bet because of the larger river bet, second, positioned yourself for an extra full bet if you fill (another jack or perhaps ace) and third, tested out his hand strength. If he has k3 he may just fold!!! also, he may be bluffing and may fold, either way your way better off with this raise. Note here if he reraises you you must fold!~

I have been doing this for months on short handed tables as part of my super aggressive play. The half bets add up!
let me know what you think about this advanced poker theory.
