Silver Opening Suite

Using the new upcoming opening suite feature in Chess for Android, I conducted a tournament between the most recent Android versions of Stockfish, Komodo, and Critter (32MB cache, 1s./move) from both sides of the "Silver Opening Suite" (300 games total). A screenshot of the tournament in progress is shown below (also note that the upcoming version improved the layout and display of the engine analysis window).

When the tournament is over, a summary of the results is shown.

The results organized in a cross-table are shown below. Stockfish is the clear winner. Komodo now comes in third (probably because v3 honors fixed time per move better than previous versions).
