2011 Tournament between UCI and XBoard Engines for Android

[tour3] [tour2] [tour1] This page presents results of a 2011 tournament between UCI and XBoard engines for Android (compiled for ARMv5TE). The tournament was conducted using Chess for Android on a Nexus One (1GHz Snapdragon). Where applicable, UCI engines were given an 8MB hash table and 1MB endgame tablebases cache (the complete 3- and 4-piece Nalimov, Gaviota, Scorpio, and Robbobases endgame tablebases reside on SD card). XBoard engines play at their default settings. Since the Nexus One is a single-core device, "pondering" was disabled. See UCI and XBoard Protocols for Android, UCI and XBoard Engines for Android, the Chess for Android Manual, and Aart's Blog for more background information.

Most engines below are compiled directly for ARMv5TE. The only exception is the built-in engine of Chess for Android, which runs on the Dalvik Virtual Machine.

Group A

Thirty seconds-per-move tournament played from both sides of all positions in the Nunn opening suite (download all games)..
Komodo2 was updated to Komodo2.03 per Don Dailey's request.

Group B

Thirty seconds-per-move tournament played from both sides of all positions in the Nunn opening suite (download all games). Regrettably Crafty was put at a slight disadvantage (not outcome-changing though) due to a misinterpretation of XBoard's resign plus move command, causing a resign by illegal move in some games. This issue has been fixed now.
Congratulations to IvanHoe for its promotion to Group A.
