I compiled the latest Stockfish for Android and as a test, I conducted a small tournament on a Nexus One phone with two other stockfish versions I compiled earlier, using an upcoming engine-engine match feature in Chess for Android. When given permission, I will put the binaries on my own website.
the question is, if the version 2.0 on "slow" hardware (related to a 2 core or quad-core pc)
is really stronger.
often versions can only show their best play and progress on a fast machine.
