Hi. The Gorrion game site provides some tools for analyzing games (see list below). The site has several games that overlap with our site, but the developer has created software (FREE download) that may be useful for players of other games, besides Chess. The GoRilla program is described below:

GoRilla is an SGF game viewer / reader / editor for the analysis and review of games of Connect6, Go, Havannah, Hex, Kropki, Othello ( Reversi ), Pente and Unlur.

He also provides a Chess tool called Penguin. I have used this for years to help me play and analyze my games. I don't 'cheat', but you CAN use it to analyze positions by adding a UCI engine of your choice.

I hope you find it helpful. mc.
