Big blind is very agressive reg from Columbia.

Is possible he is bluffing in this spot ever? or beacuse is 3way and he wasnt orginal agressor chance he bluff is less than 0.01%

Maybe im just leveling myself like a donk but he always play hands like he was shooting from maching tratattatat trattattata. My sizing can suggest i have there max JJ-QQ so is possible he turns Ace of spade or somenthing like that into a bluff? (But 3bet pot was very quick so this is unbelievable.

I saw different things on party poker, even 5bet bluffs with air on the river on paired boards thats why i think deeper about this hand

1) i could lead turn i guess
2) if i go river with 3/4 bet size i have clear situation after3bet.
This is my fault because I sometimes play very little

Finally i put him on AA or Kxxx



Sorry my english is far from the best

It is indeed very tough for him to bluff there, both you and MP could very well have a king. 3-way when it's impossible to have meaningful blockers I think sizings should be very small, so I think your sizing is way too big (with any hand). You can certainly fold everything else but a king to a huge raise like that without any worries.
