I was thinking about a raise but I called and had folded if someone after me raised it.

This is kinda weak thinking. You've got 2 outs for a FH, which beats any str8 or flush, and you have 3 outs to a str8 that would surely hold up (no reason to suspect AJ). If it's raised and come back to you for one more, you're getting even better odds than the first time around to call and try to improve.

River is close between folding and calling. A read on MP3 or SB would help tremendously (for example, if you've seen MP3 donkbet before when improving his hand, you can probably fold. If you have seen SB checkraise river before, be more inclined to fold. If you've seen them both make really strange plays and call with weak hands on the river, call.)

Also, wait with posting results until you've gotten some replies, so that the answers will be unbiased.
