Poker How to continue in this spot....

This hand is from 2-5 (1k max) at MGM National Harbor this past weekend.


I don't exactly recall everyone's stack sizes, so I am just going to guess here.


UTG (850) - Opens to 20

MP (350) - Calls

Button (2200) - Calls

Hero in SB (1200) - Calls with 6d6s

BB (800) - Calls


Flop - Ad, 3d, 6c


Action checks all the way around.


Turn - 10s


I check.

BB bets 80.

Initial Raiser makes it 210

Both MP and Button cold call the 210 and action is back to me.


What is the best way to proceed here? Everyone in this hand seemed to be a competent player and had not really been doing anything out of line...but I had only been at the table for an hour or so and some of them had just sat down.


Thanks for the advice.
