4th street play

[morgan]

I've been wondering lateley about when you can play against a paired door card on 4th. So here is a sample situation I would appreciate some input on:

Let's say you called a raise from a ten on 3rd street with split 5's and king kicker. Only you and the ten see 4th. Then on 4th street you catch a king, but the ten catches another ten. The ten's bet out. Should you call, raise, or fold? If he has 2-pair (smaller than kings up) you are a 3-1 favorite, but if he has trips you are a 4-1 dog. If he has a small 3-flush with a pair, you are a 4-1 fav., and if he has an ace-high 3-flush with pair you are slightly better than 2-1 fav. I believe all these numbers are correct. What do you think?
