My question to the original poster HS was how would he feel if the board came K 5 X would he then automatically put the player on a King ...
If he does then it's not down to anything other than the negative perception of 'Pocket Jacks' rather than a read on your opponent, and in the long term you are creating a self styled massive -EV with this thinking.
If the board came K 5 X I wouldn't have hesitated in putting the chips in. I never took it into consideration that he was playing a King. My instincs where he limped with a weak ace and hoped to pair it. I never expected him to have the two pair though.
I knew as soon as he called pre flop he was lumping it in after the flop no matter what he had.
My dislike of jacks is well served in that I cans eriouslys ay no matter how I play them they always seem to haunt me. What I have noticed though is osme times I try and be cute with them and limp in looking for a low flop hoping to get more value. Since posting this thread I have beend ealt Jacks 4 x and not lost a hand with them. I have been limping in early position and making it expensive to play in late position if - and this seems to be working for me just now.
Yesterday for example I am dealt JJ on the buttongUTG raise 4 x bb and we have another two callers and I make a pot size raise, I have nearly 3x as much chips as anyone else at the table so I washoping that I would get away with this and force all 3 off the hand UTG called and the other two players fold.
Theres just short of 2k in chips in the middle flop comes with the J 7 9 then theres a bit of speach play from him in the text box saying he has made a set and he pushed the rest of his chips in. I let the timer practically time out before calling and all the time he's typing away rapid:
Calll
Calll
Calll

Sweet I'm thinking I thought maybe he did have a set but I had the an overset. The muppet shows A 9

I think much of my thinking on the original post came down to instinct. Gut feeling is a wonderful thing and when your right its great when your wrong its not so great. I reckon I should go on my instinct more often than not its usually good.
I also agree with some of the posts about my negativity towards Jacks - but this has cost me dearly before and until I win more often with them and get confidence from playing them I am still going to think they are a bogey hand.
Which takes me to my next thread.
