By the way, Chessmetrics says Short got to #5 in the world, but Wiki says he got to #3. Anyone know which is correct?
Chessmetrics uses its own ratings formula. That makes sense for play before the ELO rating system was implemented. To allow historical comparisons of dominance, the same formula is used even after we have ELO ratings by FIDE. I am not sure how exactly a discrepancy in ranking happened, but it should go without saying that the ranking based on the FIDE rating is the official one.
Short got to number 3 in world, behind only Kasparov and Karpov. It is looking like hewill overtake Adams again as british no 1 as he will, i hope, go over 2700 again!
