Unfortunately just like Newman told Cruise..." the balls roll funny for everyone kid" It sucks when your on the receiving end of it though LOL There are 2 ways to deal with it..
1. The first you can focus too much on the rolls and start pointing them out as you prep yourself for clear a path for a definite loss. You can use the rolls as your excuse for why you lost.. Like George C Scott told Newman.. Easiest thing in the world to do is LOSE when you have an excuse.
2. The second way is you say to yourself these rolls aren't going to keep going against me all night ( and who knows maybe they will) you have to stay in the positive frame of mind. You bear down and you never let your opponent see that the rolls are getting to you. That will only pump up your opponent and make your task that much harder. By staying positive you are giving yourself a CHANCE for good things to happen and the rolls to change. If you start being negative I can GUARANTEE you the rolls will continue to go against you and your play will also suffer. In that negative frame of mind though you won't notice your poor play but instead the " bad rolls" will stand out to you. By keeping good composure when the rolls are going against you it can have an affect on your opponents game. He might start saying to himself.." man this guy is getting brutal bad rolls and he doesn't rattle like most players do, this guy is going to be tough to beat" that little scenario might throw him off his game and bring yours back.
The bottom line is you have to stay focused and say **** THE ROLLS im going to beat this SOB despite them. It is funny though just like poker players.. we remember every bad beat and bad roll but the times we get lucky don't stand out as much do they
and also when we are playing good those "bad rolls" don't seem to show up as much do they?
P.S. Phil Capelles mind for pool which I recommended the other day to everyone focuses on these type of things as well as other mental parts of the game.
