hi,
so i checked the flop because if he has QQ/JJ/TT i would only get 2 streets of value anyway so i wanted to bet turn & river and after his strange play preflop i didnt wanna get check raised on the flop and get it in against AA with A of heart or KK.
If he leads normal size on turn & river i would only flat.
But this happened instead:

Flop : (25.4 BB, 2 players) 9h Kc 5h
MP checks, Hero checks

MP bets 90.68 BB and is all-in, Hero ???

i feel like my hand is so strong and underrepped here that i have no choice but to just call it off.
