5/5 PLO

Hero in BB ($2500) AJT8 rainbow

Utg limp, button ($2200) pots to 25, sb calls, we call in bb, and utg calls

FLOP Q96 rainbow

SB bets 80, we raise to 265, button raises to 865, sb folds...

What should we be doing here? I know the button has exactly QQxx in his hand as he is tight player and wouldnt be making this move with any other holding. I know our hand is massive but unsure how to play it properly.

Thanks for the help!
