just to add, the key thing is knowing how to fish than giving a free fish. pls do not be offended by what i am abt to say.
you got to know how to look for information. it's to your benefit cos you can find results faster than relying on people to feedback to you.
in this case, i suggest you try google. e.g. type "free pocket pc games".
you can then see the very first hit:
http://www.free-pocket-pc-games.com/go in and type chess and you will find many results. happy playing chess :)
i hope this helps ;)
