How do you play JJ

My question is how do you play Jh Jd when you've raised 3x pre, you get called, and the flop comes Ad, Qc, 2h. Do I cbet? What if they call the Cbet?

If I only got called by one other player, I'll usually try a cbet. If more than one caller I will usually check to see what happens. At a full ring table it's almost guaranteed that you're going to have A-rag callers, often more than one.

Yes I agree. If you are against one player it might be worth a C-bet, especially if that player is aggressive and will bet with air if you check. Also if you are viewed as tight and solid your c-bet might suggest you hit the A so you are betting as a kind of semi bluff but with some showdown value as well. Against multiple players you have to throw away JJ if anyone puts in a large bet post flop. Too likely someone hit an A or Q. But if you are all deep stacked and the post flop bet is smallish I might call and hang around and see what happens against one or even more players. Maybe you get lucky with another J or maybe turn goes check check. Often players bet post flop on air and then check the turn and even river so you might get to showdown with a small investment post flop. Just make sure you are not investing too much if you take this path.

it depends

it all depends on the other player and position. The way you are wording the question seams like you are out of position and first to act. In this case I would c bet and fold to any raise. A c bet here should be large enough to fold lesser pairs second best hands, straight draws and air if the person is not agro. Check to the agro and fold to large bets with negative EV. If you size your bet right and get called you can check the turn. Hard to say what I would do with no info on other player. Can you be more specific?

depends notes on players etc.. id often check and if small bet back to me maybe raise a bit more see if shoves if they dont you usually can get to river no more bets and sometimes you will win to 8s 9s etc..

I would play cautiously on JJ if one player is playing with me then I can raise if several players are playing and everyone raises then I would fold JJ because players can have A or Q and I can lose on a pair JJ

It depends from position. To the left of BB - Call, to the right of BB - 3BET, Call or All In. Also I look at the my and the opponent's bankroll.
P.S. sorry for my English ))

I play aggressively before in the pre-flop ... to spit any weak A, Q or K ... after the flop bet again to know what the opponents have in hand

You want to keep the pot as small possible. Also consider a continueation bet, and represent the pair of aces. Even if a Jack comes it puts a possible straight on the board. If you put your opponent on a A or Q, the best option may be to give up the hand.

JJ play it like an AQ preflop. The strength is about equal unless the AQ is suited then it's actually stronger.

JJ = AQo = A10s = KQs

s - suited
o - offsuit

JJ is basically in the second-top tier of hands.

AA and KK are "god tier" hands so they are not even 'top tier' they are just hands you need to overplay no matter what as they will automatically profit you as long as someone calls each time you overplay them.

JJ I play,if the big blind 3 bet I do,but in other situations, always trying to open the flop,I very often lose to J J and never play at all on this card,of course it all depends on the situation but although this is a strong hand,but not as reliable as A A, K K in my opinion!

Are you in or out of position? You should check most of the time because there aren't many worse hands that will call your cbet. If you cbet and get called you should check the turn.
