I picked up pocket deuces, just sat at the table 10min ago. I called 20 (its 5-10-20),
and flop was:

2 J 8 r (160) its checked to me, I bet 80 and one opponents just calls

At this moment I put him on J, 9T, QT (all kind of gutshots) and plan is to fire
all turns and almost any river....

Turn is 5s and we have now on the board:

2h Js 8d 5s (320) I fire 200, opponent calls.

1) What might he have after he called our flop bet?
2) What is the play/plan for river?

Thanks
