Limit hand

[SoothSabre]

I'm trying to become a better limit player, but it's simple situations like this that throw me off more than anything.

6 handed 3/6 limit - all opponents "normal" VP$IP and PFR%
I raise from UTG+1 w/ATs and get 4 callers.

Flop 5c, 6s, 6d

SB bets out, BB folds, UTG calls, now it's to me.

OK very basic question - Do I call or fold, and why ?

Call.

1. May have best hand (will be hard to judge this later on if it gets HU).
2. Outs against SB's range + pot odds.
