no reads on either villain, hand sample on squeezer is way too small, but BTN looks taggish over 25hands

Do you guys would rather 4Bet vs his squeeze preflop against an unknown or rather let him hang himself postflop if he's too aggro? With positions i felt that if i clicked back preflop, one: BTN was snap folding as it would scream QQ+ and SB would of folded everything that i was ahead of preflop.

Exactly the kind of flop that i hate in 3BP, it smashes BTN range that he flatted then called over the 3B, i often see him with either a SC (less likely) or more often medium/small pocket pairs, once SB checks.. i'm really wondering what he had to squeeze preflop with, i'm completely lost about my read on him.. i'm guessing he squeezed preflop with AK, AQ, maybe KQ?

Board is getting worst, once SB check i don't think he's ever betting.. he's done with his hand, so i'm betting for protection against draws that BTN has i expect him to bet all his sets on the flop as protection and value. Would of folded if either of them raised me.

the flush draw gets there, at this point i don't beat really anything that he's betting.. JJ are checking behind and same with 55, i would have looked him up if he bet something like 50% or lower as very thin value and to take a note on his play but once he shoves, seems like an easy fold for me
