Yes, leave the thread, nao!
This is why forums don't work. I made a post thouroughly explaining my point and you respond with snide remarks. I have no wish to continue this debate with you but I would like to point out how childish your behaviour has been in this thread which doesn't exactly lend credence to your original argument.

I think the human error always allows for some luck. Even the greatest players make silly errors. I think what's important is not allowing luck to be part of your gameplan.
