Controversy

During forum discussions about early DanChess versions and the definition of clones 4, Robert Hyatt pointed out DanChess had various pre-initialized tables as used in Crafty and a quite similar SEE swap implementation 5, the latter also mentioned as extremely similar by Dann Corbit, who as a kind of ombudsman inspected DanChess' source code concluding it "clean" otherwise, and disagreed with Hyatt about both the spirit and the extent of whether or not DanChess is a Crafty clone 6. However, all controversial tracks were later removed in subsequent versions, version 1.04 was published as open source 7.
