sunday mulligan
semi deep.
villain runs 35/14 with flatting >30% LP opens. he has a 3bet stat of 3.2% no tendency to 3bet more aggro vs some positions
so therefore his 3bets are only value hands JJ+, AQs(50%),AK. villain has 5% roi with 86$ ABI on only 174 games.

here is the hand:

River: (t5835) Q (2 players)

and here my thinking process

i would say he flats with about the following range:

TT-22,AQo-A2o,KQo-KJo,QJo-QTo,JTo,T9o,98o,87o,76o,AQs-A2s,KQs-K9s,QJs-Q9s,JTs-J9s,T9s-T8s,98s-97s,87s,76s,65s (338.5combos due to card removal effects)

looking at the flop his preflop range is reduced to 281 combos.

at this point i look at my hand and believe it is 2-3 streets of value worth depending on how the board runs out.

the flop donk bet i assume is mostly top pair hands and flush draws.
i expect him to c/r 2pair, sets and big combo draws.

so his flop donking range consists of 69 top pair hands and 22.5 flushdraw hands adding up to combos i would also assign about 7 combos of random bluff hands adding up to total 90.4 combos.
against that range i  have 54% equity and i am only beat about 25% of the time in which case i might have some outs to redraw.

turn is an absolut blank as we ruled out sets and 2pairs on the flop.

now he donks the same amount as on the flop.

this bet to me loos like a FD trying to buy a cheap river, a weak Ax to pot control or a very bad random bluff. I imagine he would bet his better Ax bigger because of my perceived range which is very much Ax with x=t-2 as i would prob raise AT+ on the flop or
a flush draw and prob some floats

on the river his bet seems to be about the same as on the turn    

my questions to the hand are the following

1.) preflop range assignment?

2.) flop donking range?

3.) do you value raise flop? and then bet turn and check river to get 3 streets of value of FDs and weaker Ax?

4.) do you raise turn for value to not get freerolled? as he will make his perceived FD in about 19% of the times but is laying him self a prize for only 17%

5.) if you raise how big do you raise?

6.) are you raising the river for value?

7.) or do you just call to take some notes and probably profit on later streets more with the information you gained?

cheers for the input
