Can you have it play more games by giving it less time per turn (~2500 rating is plenty good for an opponent/coach) and playing games concurrently while it waits for human to play?

how much does a game cost in CPU time money?

How do I get the commentary for a game I played? Oh, it's in Analysis page.

It plays chess very well, but the commentary is incoherent and doesn't match the game well -- The attacks described are nonsense and the coordinates are wrong. It seems a little confused about which side is which? It thinks a rook can diagonally attack a bishop, and seems to name squares opposite from their actual name.
