I think that Kupov made a pretty good case that lower average ratings in Live Chess might well be due to tougher competition. (My own impression is that competition in Live is pretty tough below IM level or so.)
So, that's what Kupov was getting at! There may be tough competition in some rating ranges. I've been surprised at the quality of play of players in the 1200-1500 range at blitz. But, in so-called standard, this site resembles all the others at which I've played. Most opponents 1500-2000 exhibit horrendous play, but a few are quite tough. Part of the reason I shy away from time controls longer than 20 3 is the enormous investment of time for as game that might be decided by an egregious blunder.
My lone standard game this morning serves to highlight the poor level of play in the 1600s. OTB players above 1200 are rarely this careless.
Your opponent's Online rating is 1622, which is about the same as his Standard rating in Live, and quite a bit higher than his blitz rating.
Possibly maybe he is used to playing Online where you can use opening books, so you never need to learn that an early f4 is almost always to be avoided when playing against the French defence ? It would seem that there wasn't much for your opponent to do once d4 was taken out.
Also Ziryab if standard live players are so weak below 2000 why do you struggle to maintain a 1700 rating?
Karpov has hung pieces before. Your example proves that a 1600 player is capable of losing a game quickly. Brav-O.
