Unlucky. I would 4bet mostly OOP as JJ is very hard to play post flop OOP.
As played calling preflop is okay.
You can also opt to check raise the flop at a low frequency, denying equity from villain.
As played I'm folding the river as pocket pairs make for bad bluff catchers in my opinion.
Also keep in mind you are holding a spade blocker, a bad card to have as it reduces villains bluffing combos on the turn, so it slightly increases villains value portion when they bet the turn.
Maybe if you held JJ without a spade I would consider a call on the river.
Thanks for the reply. In general it's good to unlock all relevant spades, to increase the bluffs in the V range.
In this particular hand, we are blocking the Js-Qs combo. Blocking this combo ends up sentencing the level of aggressiveness of the villain, because MP will not want to have the Ac either; Kc without proper protection. At the very least he want to have a decent kicker. That is why we must add another bluff combo in our range, which is Ks-Js.
Having this combo is a real nightmare for us, since it only increases fold equity. Because it is among our dominated bluffs. But in the villain's eyes, this is an incentive to bluff with the best hands, including AK.
Of course we are also blocking QJs, which tips the balance of rank V towards KQ + combos. But if the villain thinks he can knock our Ks-Js down, possibly the count starts from AQ+.
The important thing is that our range is balanced on the river. We double the value combos for each bluff. In fact our most important values are: 2 JTs combos + 3 JQs combos + 1 combo of 4-4 that we have played slowly. While our most relevant bluffs are: 1 combo: Ks-Js; 1 combo: As-5s and 1 combo: 6s-7s.
While range V has:
RV values:
3c: QQ
2c: JTs
3c: 9-9
3c: 8-8
12c: AQ (s + o)
12c: KQ (s + o)
12c: AA + KK
Total values: 47 combos.
RV Bluffs:
6c: T-T
16c: AK (s + o)
1c: As-8s
Total bluffs: 23 combos
Proportion of bluffs, with respect to all combos:
23/70: 32.86%
Our fold equity: 3 bluff combos / 9 total combos from our river range: 33.33%
When we call on this river, the pot is $ 89.09 (net of rake) and we have to call $ 28.67, so we need 32.18% equity to have break even. We see that with a % of bluffs in the V range that is 32.86% we reach this requirement. And we are slightly on the positive side of our EV.
