You may know DanChess but you probably remember Scorpio, one of the strongest WB/XB engines which played at TCEC. They both belong to the same author Daniel Shawul and DanChess was superceded by Scorpio in 2005.
DanChess is not rated by CCRL. However, to give an idea of the level, i've found a few sites with ratings around 2550 on a PC where Scorpio, thanks to SMP feature, could climb higher around 2700+.
On Android, we can expect roughly 2300 ELO from DanChess.
Enough said, collectors may download DanChess 0.4 compiled by Jim Ablett: HERE
