My two cents, grain of salt required:
He's got a super wide
range preflop, obviously. I think he
check/calls your
flop bet with a bunch of shit, basically any kind of
draw and any
pair.
When he then
donk leads the
turn, I tend to think of his
range as being made up mostly of draws (
flush draws, AK, KJ, J9, 89) trying to see a cheap
river card, or retarded shit like 44, honestly maybe even 42s that has just hit big and so he's value betting. I think it's not unlikely that he then flats your bet with that whole
range, the draws 'cause he
ldo wants to hit, the value hands 'cause he doesn't want to
chase you out.
When he
open shoves
river I'
m pretty much thinking he's hit his gutterball or he's like "
flush didn't come in, my 44 is good, yippee"
So yeah, I
fold river here even if we're getting bluffed a small amount of the time. Also I make it $0.50 preflop and
raise the
turn probably at least $0.50 bigger than you did.
