Ponz, if chess and bowling were related, then most pro bowlers would be very good chess players, which is not the case! So how do you relate the two? Oh I would not call Denver an amateur bowler. He is almost pro level if not at his best! This is real bowling not like your wii -wii bowling Just thinking if there was a competition that had two pro bowlers and each had an amateur bowler, say like myself, 160 average or you, that would be fair, but if a pro had Denver as his team mate that would be very unfair!
Ghost, it takes years of dedication to become a pro at chess, bowling, tennis, futbowl, baseball, poker, dupicate bridge or football. Thus you will rarely see someone who is a pro at both.
However you will see strong amateurs who are quite good at any two of the above. [such as chess and poker or chess and duplicate bridge]
There is much more of a correlation between chess and duplicate bridge and poker than there are to the other sports mentioned above.
The bowling stuff looks like pawns for a distance...
