First off, I am a complete beginner & basically do not understand half the terms you used above.
I can only say what I have done in this situation as it happened to me yesterday.
Another person who I had noticed only bet when he had something decent, bet something like $300 after the ace came down.
I folded my two kings even though it was very hard to do. He could of been bluffing
however I have found that the odds
are usually a person is not bluffing. So I tend to assume they are not bluffing unless I have seen them play for a little while and been able to catch them out.
