I think that such a move is dangerous, I have repeatedly seen the player who put an all in with JJ, took off from the tournament.I just go straight all in with JJ in tournaments and hope to get called by a lower pair.
Yes I quite agree with you, sometimes I call this hand, A hand for loss.JJ is a very complicated card to play, since it is more than anything a 50-50, if the flop do not appear superior cards you have to bet hard to protect your hand
Yes, it is especially difficult to play with them when on a board there is a card J is more senior.The reason why JJ is an awful hand is because it's hard to fold them, to be winning in the long run with JJ you need to fold a lot of times.
