Perfect Bluff gets wrecked.

Me and a very loose player are left in the hand, he usually calls with 56 and other bad hands, but i am used to his style of play, if no1 bets he will take the pot down himself by betting big. I have ace jack pre-flop and raise he is the only caller and the flop is QQ4 we both check fearing the other has a queen. Next card a 5, i check, and he raises about 5 times the BB, i know his style so i move all in and quickly he calls. I flip over my AJ and he flips over A 10.. kind of a stupid call if oyu ask me but i was gonna get paid off big.. but of course since this is poker the river was a 10
QQ,4,5,10 his pair of tens beat my ace high.
