Look friend, JJ is a hand in which many people have called it fatal.
For me it is one more hand that depending on the position you play it in, it can bring you many profits.
Also the J is a very salient card in the showdown.
From now on, it all depends on how lucky you are.
The position for me is essential.
If they openraise me from UTG with 3 bets and I'm in another position, I only pay.
If there is someone who raises 4 bets to the open raise, possibly depending on the players I am up against, I either limp or fold in case there is a possible stronger hand.
But it's a very playable hand for me.
My regards, brother
