I am an A player and I think i can beat a B player on average 7 out of 10 games.
ELO Difference For Domination Levels?
Sort:
200 points higher rating = 75% victory, which matches the numbers above.

Sporked from wikipedia. The first column is expected performance, the second is the differance in elo ratings. If someones expected performance was 0.6, they would be expected to score that much on average using the win = 1 draw = 0.5 rating system in 1 game.
Note that at lower levels - elos system tends to be inaccurate. I would give more then 10% odds to a 801 rated player beating a 1167 rated player for instance.
0.99 +677 0.9 +366 0.8 +240 0.7 +149 0.6 +72 0.5 0 0.4 -72 0.3 -149 0.2 -240 0.1 -366 0.01 -677I would guess that 700 points of rating difference would mean a guaranteed win at lower ELO levels, but not at higher ones. For instance, I am pretty sure a 1,950-rated player could beat me as many times as he/she wants (be it once, 10 times, a 100 times, or a billion times theoretically). However, could Carlsen be certain of defeating a 2,100-rated players in as many games as necessary? I doubt it.

mmmmmm. I don't doubt that. Super-GMs can pretty much beat an Expert rated player at will. I'd say maybe the guaranteed win diminishes against a 2200-2300+ player. The Master threshold is different.
What ELO difference would result in:
If necessary, just answer the last one. My real question is the ELO difference required to beat an opponent consistently in many thousands of games without losing or drawing even one. I know that such a difference exists (I could be beaten in this way by any 1700+ player on the systems here, I'm sure).
