NLHE hands.

1) I would just lead out $1.5-$2 unless I have a read that he vbets fairly wide on the river.Problem with c/r is he is likely to bet something lame like $0.8 then fold to your raise when he would have called a psb in the first place.

2) Raise pre you don't want 4-way with your jacks and there's a nice load of money out there. As played raise flop more (always remember to look at the size of the pot not opps bet, your raise gave really good odds for a FD.) then with the d out you have to shove the turn. On a non-d turn I might find a c/f depending on opp, but then I'd never be in this situation since it's sucha clear raise pre.
