1.THE "eightball cheat":

When your opponent bouta make the eightball(when he aiming for it) just close the lobby not the table that you are playing on.(Works cause Yahoo ! can't handle 2 things at once).

*If someone did that to you when you are about to make the eightball, just wait 30 seconds before making it.If it is a timed game - even better!-Miss the eightball on purpose, wait till your opponent's time is passed,then you will get the ball in hand.And when you do , shoot it in after 30 seconds on the timer (it will be 3 minutes cause you have ball in hand) pass.

2.Playing urself cheat: 1)Login to yahoo.2)Then enter a pool room. 3)Then without closing the room, sign out. 4)Sign in by a different name 5)Go to a backdoor(any backdoor ok).And go to the same room ur 1st id is in. Oh, and if in a back door it says id#(some number) dont change it unless its not 1 or "default". You can now play urself(which id gonna win all the time- is your choice). 3. "Ghost Boosting" cheat(its a cheat becuase there arent any boosters involved).I hardly get how it works , so I cant give ya any tips .If you dont know how to create ghost id's  click here.
