Wahoo!!! 4 callers!

Today I'm playin in a loose 3-6 game. There's one guy that raises about 70% of his hands. and this could be anything. He is UTG+1 and raises a limper. 3 cold callers in between to me with pocket 10's. I call. As it turns out we go 7 or 8 handed to the flop.


Flop: K, 10, 5 rainbow.


It gets bet and raised with 4 players to me. I just call. We go 6 handed.


Turn: 10


Now it gets check all the way to me. I bet and get 4 callers!


River: A


I bet and no-one calls!. What the hell are they playing?

Since these folks will call with very weak hands, you should definitely 3-bet the flop. I understand that you were waiting for the turn to pop them but, if they're going to call, just keep raising.
