This is an interesting hand from NL500, and a spot where a lot of new regs will be too passive, but in spots like these we should be more active when we have a range advantage
CO is not a reg but BTN is. It seems at first that we should never bet JJ on this flop, due to 2 overcards, but the truth is that we should be betting flop a lot because we have all the strong hands AA, QQ and AQ, while they don't because they would isolate these hands preflop, so we will get a lot of folds on this flop, and even if we don't, we can continue to put pressure on a lot of turns and rivers. I get called by CO and turn is a good card for me, now J10 makes a straight and I have JJ so its very unlikely that CO has J10. CO also can't have AK or KK, so the best combo he could have with Kx is KQ. Because my oponent can't be that strong, we have to continue betting. River is a blank but my oponent still can't have sets or straights so we jam here, I think he is capable of folding 2pair here even, something like KQ is not very strong here and is essentially a bluffcatcher
