This situation has come up a number of times...
I raise 4xBB with for example AKs out of position, i get one caller and the flop comes 2, 9, 5 rainbow and i fire out a bet of roughly 65-75% of the pot, the other player calls again and the turn comes something like a 10 i slow down and check, the other player bets the pot and i fold...

After this happened a number of times i tried calling down a couple of players that did this and it turned out they had really strong hands like 2 pair a set or an overpair... What is the meaning of this strategy 95% of the time they dont get a call, dont they want the other players to call?
If not is it a play to enable them to bluff alot later?
If so arent they taking unecessary risks with their money?
