Your mid position with TT in the hole.
You call a pre flop riase of 400 from UTG. And there are other 3 other callers. Your notes on UTG read "loose player likely to push with bottom pair or any draw" And sure as heck he pushes.
3 hearts on board J 6 3. Now its early part of a deep stack tourney is this just a standard fold or should I consider making a call?
Given what you know about him and given the betting that's gone on I'd say he's probably got the Ah with a non heart K or Q kicker
So by my count he has 13 outs and is a slight favorite with two cards to come. I think that's the best you could hope for. He could also have AA, KK, QQ and is trying to drive out anyone with a heart.
There's also still 3 people to act behind you who could have anything so on balance I'd say this is a fold.
