Tri-State Chess Club Ladder - How What If Works
- I was asked by Wolfgang
(rating 1771) and Neal (1688) what happens to their rating if they won
or lost.
- If Wolfgang wins against Neal, his rating would go up 9 points. If he lost his rating would go down 14
- If Neal wins against Wolfgang, Neal's rating would go up 16 points, If he lost, his rating would go down 10
- If they draw, it is treated as a half win and a half loss. So Wolfgang would go down 2 points and Neal up 3
- The difference between the above values is driven by Wolfgang being 83 points highter. Color doesn't matter.
- Another
what if question is what happens next week (7/29) if Bill Mendenhall plays
Bob. The two are very very close, Bill just 12 points higher!
- Bill would go up 15 if he wins. And down 15 if he loses
- Bob would go up 16 if he wins. And down 14 if he loses.
- So, if Bob wins, there would be 31 point swing between the two, and Bob would take over 9th place
- Don't worry Bill. Bob is after Van Woolley :D
- If
two highly rated players play each other, the up and down values are
lower, about 8 points for a victory or loss..
- If two players far down
the ladder play, there is far more movement. If Charles plays Bruce
(both around 1250), a victory or loss is 21 points.
