Ruffian 1.0.5 is the same as previous versions which were also free.
Arena is an interface.

I specifically refer to Ruffian and it becoming commercial. Without "Arena" it's
hardly likely that Ruffian could become commercial as a simple winboard engine,
and no interface of it's own.

You may though wish to change the statement;
"Ruffian has a lot of endgame knowledge and can play endgames fairly well."
I am not even sure what "fairly well" means?.

Sarah.
