 * IsiChess** is a private chess program written by Gerd Isenberg. A former DOS-version of IsiChess was commercial from 1994 until 1997, distributed exclusively by Martin Stamer's EuroChess Zentrale. It was able to play simultaneously on up to ten boards. The Windows program developed in 2000 was a complete rewrite influenced by Robert Hyatt's Rotated Bitboards paper . In the following years IsiChess evolved to a pure fill based approach, motivated by the ideas of Steffan Westcott. It used two threads sharing the Transposition table.
