I'm participating in some engines-on correspondence games at ficgs.com. To assist in my analysis of my games, I'd like to set up a chess engine (probably Komodo9 which I own) to play moves against itself after a certain time interval. Do any of the UI's like SCID or Arena support this? (Droidfish on my phone does but that won't do) And if so, what are the steps to achieve this?

Yes, Arena can do what you want.

  1. Download Arena 3.5


  2. Adding Komodo (or any other engine) to Arena:

    On the menu select Engines -> Manage Open the Details tab Click the new button Point it at the executable Select Ok

  3. If you want it to play itself from a certain position you can set up an engine tournament using an epd file to set the position you want the engine to play from, and then in the settings for the tournament if you hit the level button you can set a fixed time intveral, or fixed depth for the engine to play. To create an epd file, you can copy the position from Scid using Edit->Copy to FEN, and then in Arena using Position->Get FEN from Clipboard, and then EPD->Save Position in EPD Format. This file would then passed to the engine tournament dialog.

    There might be a way to get it to play itself from a position without using the engine tournament, but I'm not that familiar with the interface.

  4. If you want to have it analyze a game that has already been played, or what has been played so far can use automatic analysis under the Engines menu.

Arena seems to have a pretty thorough help file, so most of your questions will probably have answers in there.

Edit: It was pointed out in another question that the demo button in Arena will have the engine play itself. So you can just set up the position, make sure komodo is loaded, Go into Level->Adjust to set the time interval you want for moves, and then hit the demo button.

  • +1 for the <--> Demo button, which works much easier than setting up a tournament (which requires setting up the same engine twice in Arena.

If you use Arena 3.5, you can set an engine to play a game by itself or even two different engines to play a game between them.

Just go to Engines->Manage... and there add any engines you want on the Loaded Engines.
