Zerowin is a bot on FICS. It plays chess 24/7 using the stockfish engine to select its moves. Zerowin was created to run strong windows engines in GNU/Linux via Wine, deriving its name from "zero windows". It started on a 2.1 Ghz Athlon XP, but now it runs on ARM hardware using native GNU/Linux binaries. One of the goals is to foster interest in computer chess by providing a decent testbed for other computer accounts. So, Zerowin uses a formula that permits extensive unrated play.

- Jun 30, 2017 Taken offline. I'm pretty much done with the hobby.
- Nov 01, 2016 Updated to Stockfish 8
- Jun 30, 2016 2034 days online, 61% since May 2007
- Jun 06, 2016 Included binary that Zerowin runs after being told it works for rpi3. Probably requires debian based distro with libc and libc++. Maybe some will find it useful.
- Apr 18, 2016 Replaced Orange Pi+ with Orange Pi PC. Same SoC, voltage, and bench. 1.3 Ghz works well, and the PC seems to run cooler. May add cores eventually.
- Mar 30, 2016 icsdrone-> 0.29, experimenting with voltage/core speed: 1.3 Ghz (227051 nps bench)
- Jan 05, 2016 updated to Stockfish 7
- Dec 30, 2015 updated hardware to Orange Pi+ and software to Stockfish7Beta2
- Feb 11, 2015 updated to Stockfish 6.
- Jun 01, 2014 updated to Stockfish 5.
- Feb 14, 2014 Bot temporarily offline, will connect sporadically. 24/7 will resume eventually
- Aug 21, 2013 updated to g++-4.8 and stockfish 4 and appears to be another 10% faster.
- Nov 16, 2012 updated to icsdroneng 0.28.
- Oct 12, 2012 version bumped from 2.3 to 2.3.1. This build is about 8% faster than previous builds due to also upgrading to gcc/g++ 4.7.
- Sep 21, 2012 added support for wild games by upgrading icsdroneng to 0.27.
- Sep 17, 2012 version bumped from 2.1.1 to 2.3.
- Oct 23, 2010 Approved to run Stockfish on the Seagate Dockstar. So most of its archived games are, unfortunately, with a different engine on much faster hardware.
- May 15, 2007 Operation began running the hiarcs engine.
