Round 6 Pairings

Maybe if you have time you can explain to me the meaning of all those numbers? or point me in the direction of an online resource. thanks for all your work

First column is board number that doesn't apply to online but is part of the pairing software
Second column is wall chart number e.g. No. 1 (S3717) is the highest rated
Third column is where you would write the result if you were there in person
Fourth column list the players handle and three items in parens:
1. Rating
2. A cryptic pairing code that tells the TD and software what color the player should get. E.g. brutalthrasher2 has a code of "WW". This means he had Black two times in a row in the last two rounds so he must have white this round.
3. Score after last round
