In some tournaments in Chessmaster in between the score and the bye sometimes the status bar OPS appears. After you play a match is displays a number which changes after each match. What does it stand for?

I assume it stands for your Overall Performance Strength/Status for the tournament up to that point, yet it could also mean your Opponent's Performance Strength/Status.The computer tends to adjust the performance level of individual opponent to constantly surpass the level of the player's performance between 200 to 500 points.

Example: I sealed a win with an OPS of 2639. My opponent for round 2 has one draw and an OPS of 3138. The tournament is the 12th pre-determined round robin tournament (The Valliant Chessmen) with rating levels between 1100 - 1500. If the OPS does stand for Overall Performance Strength isn't that a tad bit excessive?

I've checked the Chessmaster help function and googled Chess OPS, yet I couldn't find anything on the matter to confirm my thoughts. Anyone have any clues or ideas?

In case anyone else has this same question...

OPS - opponents strength
It's the average rating of your opponents in the tournament. Note that the average is calculated from base ratings, not the displayed ratings (which are adjusted to your computers speed).

So I sealed a win with 3138 for my performance in Game 1? Did I break Chessmaster? It only agrees with 80-83% of my play (depending on depth of anaylsis) then again Chessmaster looks for the quickest way to victory.

I wasn't playing for the win or searching for the best moves, my purpose of the game was completely unnecessary sacrifices and knight endgame training so I searched for the moves that would best swing the game to that effect (unnecessary sacrifices can be seen as obvious moves are intentionally missed for the purpose of training - ie 42. Kg2). Enjoy the "horrible moves" and amusing sacrifices (a lot of which will involve WHY?!).
