UTG+1 85/15 over 34 hands (thats why I went 4.5bb preflop)
MP+1 19/15, 3b 7.5 over 246 hands
BTN 43/18 over 456 hands (he is pretty aggro postflop, but will fold a lot till the showdown, esp. aggro OTR seen some bluff-raises/stabs)

MP+1 is more of an aggro 3bettor so far, not sure if I should also consider jamming option.. just scared of getting called by JJ+,AK.. jamming QQ+,AK? or slowplay AA? What about AQs,AJs?

I was considering min raise and call. I believe if I would have jammed, MP+1 might even fold an overpair, whereas if I minraise the flop, I doubt he would find a fold button.. On the other hand by just calling, I am also inviting the whale to play as well and call with some AJ,AQ type of hands, but yeah giving him also great odds with 87s,KJ,KQ,QJ and FDs.. therefore I prob do like minraising the most, since the BTN would still call with draws and MP+1 (hopefully) with overpairs

In case you agree with the flop call, what would you do on this turn? I mean MP+1 has usually JJ-KK which are clear check, but BTN seems to be more on the aggro side, so checking and letting him to bluff or just jamming ourselves? I think its heavily dependent on how BTN is playing his draws when checked to him.. if he is in a xb mode with QJs, and other FDs, we are better off donk/shoving (I have 35.85$ left)

Now I doubt that any player has an Ace so I am putting them on 2rdpairs and worse + some flushes.. therefore I decided to use more de-polarized sizing with intention to call if the BTN shoves and fold if MP+1 shoves.
