As soon as he calls the bet on the turn you need to have your spidey sense tingling. You are really betting as a bluff, because nobody with a better hand will fold and nobody with a worse hand ls going to call (possible exception of a straight draw). Check/call a small bet on the river - don't go all-in there.
Notice that even if you had a J you would have lost, because he had a better full-house. That would have been a cooler. This wasn't.
all the way through a hand you need to keep changing what you think he has based on what has happened so far in the hand. while thinking about how you want the hand to go from there. sounds complicated but in poker you have to have a plan for each action you make and adjust it for the situation.
He can definitely have some jacks in his range, since it would make sense for him to check the flop in the hope that someone else will take a stab. On the turn, he doesn't have a chance to bet, because you led into him. Since he called on the turn, he either has a made hand, or a draw. The most obvious draw (flush) got there on the river, and that will usually bet if you check. Jx and KK will definitely bet, but hands like QT/AT should also be betting as a bluff. I would check the river to induce those bluffs. With the worst possible boat, I think you should only be check-calling the river. The only hands that should play for stacks are better boats/quads.
The old saying "Don't go broke in a limped pot" applies here. A full house is a strong hand, but in a multiway limped pot, you have to be on the look out for even better hands.
Yes .. This is a pretty classic tale of trouble here ... You pretty much need to c/c the River here and play this off like you have a Kx hand. You want Kx and the flushes to bet out on the River and you really don't want to call off more than one 'reasonable' bet against the Jx hands.
Initially I was going to say that V was taking a risk with the flush draw out there .. but obviously with a FH he 'wants' all the draws to come in so betting the Flop might scare away any more value later in the hand.
He flops a full house because he not only has a Jack but also has a King. If he bets, how much action is he likely to get? Only one other player can have a Jack, maybe one or even two has a King. A weak King might even fold to a bet.
However, it's possible that other players have hands like 77 or Q10 or something that could become a very strong hand on later streets (albeit not as strong as your villain's). Your villain wants to keep those players in the hand and then stack them when they hit something they think they can reasonably bet with.
If nobody hits anything then he's hoping checking down will induce at least a bluff on the turn or river.
