Call the all in raise
I think one of them has a club flush draw, K9 looks a possible, as does 9 with better kicker than u. One other possible is one has pocket 5`s
I doubt if you call the raise the other guy to act will reraise, unless he has the major nuts. He will probably call. If he does reraise, u have a decision.
I would love to say I would fold but I don`t think I would.
Worst case, if u r behind, u still have outs. Only hand u r almost dead to is pocket K`s. U even have an out in this situation - the last 9.
Using a % to work out where u r, IMO
60% U r ahead
30% u r behind
