PS: I didn't understand the meaning of the table and the meaning of the letters, but I'm available to understand...the more I learn the better
The table shows how the chess rating formulae work.
An advantage of +50 points in rating only gives you a 57-to-43 edge over the low rated player.
An advantage of +100 points in rating only gives you a 64-to-36 edge.
An advantage of +200 points gives you 75-to-25. Three-to-one.
This is the mathematical expectation built into the rating formula. It describes how the curves are shaped (if you drew the rating formula on graph paper).
... so if you played an eight-game chess match against a player who was rated 200 points below you, and you won five games, drew two games and lost one (total: 6-to-2), then no rating points would change hands, plus or minus, because 3-to-1 is exactly the mathematical expectation for a 200 point difference in rating.
always check blunders before you play them
.....Is their an app for this ?
I seriously need a cattle prod connected to my laptop/ 'phone .
