I have no idea what you want me to say?
You appear to be asking is there anything different you can do other than check calling 2x pot on J77 flop with JTss 89ss Akss and betting 1.5x the river on a 9x3x runout?
In answer yes. There is a lot of different things you can do
obviously.. but with that range of my hands, we have two pretty nutted ones, one that can 'turn' a lot of equity and a medium strength hand that should be able to be 'good' a lot on this board....
He is bluffing somewhere between 0% and 100% of the time. If you are readless then can only go on what you know, ie stakes, location, population tendancies of both of those and add into the fact he has taken a non orthodox line of betting 2x pot. Then you derive a figure. Add this figure to the % of times your hand beats his value shoving range that you beat, ie when we have JJ we beat some hands, he doesnt just have 77. If its higher than 13.5% then call, if its not fold. It really isnt hard.
That part isn't hard if i were good at constructing ranges with which to work out the following...
Clearly we should be able to be 'good' here with the A7/ JJ more than enough to be ahead and quickly press call.
What I was struggling with is working out the JT/ 89 river calls.
I started by giving him a flop range of
AJ, QQ+, all 7x, T8, T9, 22-66, a couple of complete airballs and a couple of Ax bkdrfd hands.
Develop this on the turn by dropping out some of the overpairs as I don't think he would check them back 100%.
Then take out some of the T8 as he surely would bet some on the turn
Take out a couple of the small pair combos - he tried once to 'buy it' and that didn't work
And on the river take out all the 1p hands as he would either call or fold imo
which leaves a river range of 7x, some T8, some T9, and an unidentifiable amount of complete bricked air... potentially even Ax/ Kxdd hands because of the turn check back (didn't want to get blown off his hand)
Make sense?
