I dont think pushing the flop is good at all. If you fold this flop you will be left with 2600. WITH SOMEONE WHO LIMPS ALL THE TIME DIRECTLY TO YOUR LEFT. I mean WTF people what more could you ever ask for. Blinds are petty big, this should be the easiest tournament ever.
#1. If you are pushing for value here; which none of the posters have implied so far, you need help.
#2. If you think that he is folding his Jack or 6 I think you are likely mistaken.
#3. It looks like he does not know what he is doing. So why would you push when you give him a flop. Thats all he really wanted right? To see a flop? Don't make 2 mistakes in one hand by giving him all your chips too.
