Hero Ac9cTx5x cutoff with 700 stack TAG-IMAGE.

Somebody raises to 20 hero calls and bt+one off the blinds and the fish on straddle completes.

Flop A98(100 in the middle) Everybody x to hero who pots.
Rest folds and fish calls. Has about 500 when hand started.

Turn 7x fish x, hero x

River 4x fish bets 200 into 300 hero?

Okay we can most likely EXCLUDE any sets on the flop as that will most likely be a donk-bet or x/r from fish.
Fishes calling range are VERY-WIDE but it will be something in there.

Dont see much point off betting turn as I am never getting called by worse and gii vs JTxx would suck(Have see fish x with nuts oop)
So what to do on river? Most off the ''draws'' got there can I make a profitable call here or? Is x-back on the turn good?
