Home * Engines * Stobor

a private chess engine by Tom Kerrigan, reportedly commercially available under a different name(s) [1] . It's named after the bogeyman character in Robert Heinlein's book, Tunnel in the Sky [2] . Stobor is also "Robots" spelled backwards.

Stobor played two World Microcomputer Chess Championship, the WMCCC 1995 in Paderborn and the WMCCC 1997 in Paris, and further the IPCCC 1997 [3].
The Bogey-Man is coming [4]


from Tom Kerrigan's Home Page [5] :
The first version of Stobor was mainly influenced by a paper on CHESS 4.0. It used attack bitboards. It was slow and never very stable and I rewrote it at the beginning of 1995 to use precomputed move tables, like Ferret and GNU Chess 3. I rewrote most of it again in 1999 to use 0x88 and implemented parallel search in 2003. Stobor and I owe a lot to Bruce Moreland.
