As you know, the Filter Games window has an Elo box to filter games by rating.
However, the first box is the minimum Elo and the second box is the maximum Elo rating. The minimum number entered must be lower than your maximum number.
But as you probably found out, if you enter 2300 and 2500 in the first and second boxes respectively, you get all games played by players specifically within that rating range. But according to your question, it sounds like you want the opposite. You want all games where the players are rated > 2500 AND all the games where the players are rated < 2300. To clarify, you don't want the games where players are rated within the 2300 and 2500 range. Is this correct?
If you enter 2500 in the first box and 2300 in the second box, you, understandly, get nothing. Again, it's because the first number is the minimum rating and this number must be less than the second number.
I don't see a way to do what you want in one step. But you can do it in three steps.
First load your database and select all the games with players rated > 2500. (Select 2500 in the first box and 9999 in the second box.) Save this filtered database as a new database.
Then load the original again and select all games with players rated < 2300. (Select 0 in the first box and 2300 in the second box.) Save this filtered database as a new database.
Then, simply merge these two new databases together.

^ I want the games of 2500 played against 2300 - I want a 200 point rating gap!
Ah.
Daeru is correct. There is no way that I know of to filter that.
Do you have any programming skills?
If so, you could write a quick and dirty program to open a pgn file for input and read in each game. You could look at the pgn tags and only the games that meet your criteria would be written to a new, output file. Simple stuff, (20 minutes work) if you know BASIC or C or C++ or Pascal, etc.
Hi, i'll cut right to the chase. How do I specify the rating parameters in Chessbase11?
I know how to specify 1 rating, but let's say I want to see every 2500 vs 2300 game, meaning >2500 and <2300?
thank you so much
