if its in the Philippines, where pool players are like Efren Bata Reyes, the person who always accepts a challenge always is a greater player. in your case the guy is just trying to earn money for free. if you beat him on the game easy, then you know the challenger is up to something.

they do have a lot of guts for a fight knowing you got an agreement. if you are not from that place you did a good job escaping alive.
