his flop raise seemed so weird, probably a PP is this ok? i think this exctract more value fo PP or 3 bet flop?

3 betting flop is a bad idea, decide if you want to call a turn bet on the flop and if the answer is yes then check call turn. Otherwise id probably just fold the flop unless hes passive and will check behind.

if u reraise the flop hes almost never going further with a worse hand. If u check call the turn he can either have u beat or be bluffing, if you bet out the turn hes almost never going further with a worse hand and your putting more $ in the pot.

yea its hard to tell what the flop donkey raise means, if he's seen you cbetting a lot it could be anything. bluff, monster, T8, pp...

Without too good of a read I think check-call turn is ok (c-f also ok if he makes a real bet).

3-betting flop def a bad idea, although i think folding flop is too. because theres quite a few 1/2nl donks who if they think youre cbetting too much will miniraise flop, fire a second barrel if checked to, then give up on river 99% of the time unimproved.

i guess to clarify a little i would say call his flop donkraise, on turn if he bets over half pot c-f, under half pot c-c (can switch this amount around a bit depending how you feel at the time), and fold to any river bet that isn't retardedly small.
