Call me a nit but it amazes me to see how many people get out of line in games. Part of the problem is that most guys want to steal instead of gamble, whether its the guy giving up weight or asking for weight. That being said knowing ones own speed in the most honest possible way is really really important. Take me for example, I havent been playing too long and know I can run 1 full rack of 9 ball on a big table every say 6 or so games (need to play 9 ball). However there are a bunch of guys who beat me in 9 ball that can't in one pocket (because I play it a lot). I run balls decent in 1 pocket and know a fair amount of moves and shots. However, I also know that 1 pocket is by far, the EASIEST GAME TO STALL IN. All a guy has to do is play a little aggressive and his opponent will just think he is aggressive lol. So besides asking everybody in the pool room and looking at fundamentals, how do you judge speed?
