Well I've only been a Legend a week but a few weeks ago while a T/M I played a Pro who had only been on WGT for 4 weeks. We played a M/P game on Oakmont which I'm sure most folk would agree is a tough course and takes many hours of practice just to finish on level par.
I went 2 up only because he said his meter was acting up but then he proceeded to get to get back to A/S and won the game 1up.
As this was a friendly game I wasn't that bothered. It's just that when I think back to when I was on WGT for 4 weeks there's no way on God's green earth I could have beatn a Hack on Oakmont . . . never mind a T/M.
I suppose it's the hurt pride that makes you think "this dude must be a multi-accounter" but no doubt some folk just pick things up quicker than others. I've seen my sons join gaming websites and in no time at all they're beating everyone.
As for Blitz games . . . they're an entirely different entity in my view and a lot easier to master in a shorter period of time.
Sport is littered with underdog stories . . . Boris Becker enters Wimbledon as a 17 year old unseeded player and ends up winning it. Did people say "C'mon Boris . . . you must have played tennis in a previous life!"
Well . . . maybe they did :)
