Good afternoon,

Got in to a small discussion with a friend who's game i respect and is SB in this hand.

Stacksize:s (stacksizes and betsizes can be off a bit)

Utg +2 150 euro 

Btn 2400 euro (mark of the game)

SB 1700 euro (friend, most competent player at the table)

BB (hero) 600 euro (Tight and trying to transition to PLO)

Hand:

UTG+2 and a few more limpers when button pots to 22 euro, SB calls , im BB with AThhKJ and squeeze pot to isolate button to 116, Utg+2 calls, button re-pots to 360, SB folds

1) would we rather flat pre to play multiway (friends preferred option)

2) were not doing that well against Btn's 4betting range, but can we really fold?

any input would be welcome,

Kind regards, L
