I'm new here and enjoying the play. However, I'm curious about how the rating factor is determined. Don't really want any algebra formulas, just simple Laymen language. Does number of moves, win-loss ratio, pieces left on board at checkmate, etc. Any help and information is appreciated. thanks!

You basically play about 16 points.
If you beat a stronger guy then you get more than 16, if you beat a weaker guy you get fewer than 16.

But your rating is still provisional until you've plaed 20 games, so the rules for rating calculating is somewhat different. Might appear erratic but is correct anyway.

You'll see, the system calculates it automatically.

number of moves and pieces left on board are completely irrelevant

any finished game is a win, loss or draw. doesn't matter in how many moves or how it's ended (a win/loss may be by checkmate or resigning). so, the score for a game is just 1-0 or 0-1 or 0.5-0.5.

then, based on (score. your and opp rating), a new rating is calculated.

See http://en.wikipedia.org/wiki/ELO_rating_system If you use the analysis board and opening books/databases deduct 500 points from your CC rating to get a comparable OTB rating.

My RHP rating at present is less than 100 higher than my OTB. Both appear to be climbing. I doubt that databases have helped my rating much here, either.

OTB is a sum of your ability under time pressure to :-
- analyse
- play the opening, middle and endgame
- use your own abilities without outside help

If you use opening books/databases it means you are playing at 2500 level for those stages, so you need to re-adjust for this infringement of FIDE rules. If you are using the analysis board you are also playing much higher than your OTB capability and so you need to re-adjust too.

If OTB had no time pressure, you could use analysis boards and books not only would that be a circus but that is not chess, you would have to call it something else.

The moral to this - learn your chess "properly", your chess is only as good as it is OTB.

It depends on the database. If you are using the largest ones, the average player whose moves are contained therein is closer to 2000.

Players over 2500 author novelties as a rule at some point in their games, following established moves only when they are playing out an arranged (or mutually desired) draw.

Still that constitutes "help" unavailable OTB and so results in the CC player playing out of his skin relative to his OTB play. Compounded with the lack of time pressure it is similar to a player playing against an engine and then using the pause button when it his turn, moving the pieces around and then restarting the clock. Are those results that the player would garner in OTB conditions?
