FT 50-100

[ship it pls]

Lost quite a few hand histories because I am computer illiterate, but this is one of the few I remember from this month and wanted responses to before I completely forget it…
Game is playing wild to say the least...
2 folds, hero opens 6s6d, button 3ball, sb 4, bb calls 4 cold... and we see capped 4 way flop of As6c4s

Flop: sb bets, bb raises, hero 3balls, button folds sb calls and bb caps - no reads on sb, he is in second round... bb has no brakes
Turn: 3s, sb checks, bb donks, hero raises, sb takes 2 cold and bb 3-bets, hero?
