Best chess games for PSP?

What are the best games for PSP? On my PSP I currently have Chessmaster 10th Edition and Online Chess Kingdoms USA. 

Best as in - for learning

              - for fun (like those where your chess pieces are 3d soldiers and when you capture your opponent's piece it shows your piece killing it)

I would say for learning forget PSP and get deep RYBKA 4/5 or shredder chess engine/chess tutor software and use concurrently with a diamond membership on this site, that and talk/listen to IM Rensch, he's really good at getting beginners on the right track.

oh and Roman Dzindzichasvili DVDs. if you are serious about learning chess that is the way to go.

Thanks for helping bro, but the point is I can't bring my computer everywhere or to the toilet ;) I have a coach alright, and Fritz on my computer. So all I want now is a game for my PSP to play when I dont have access to my computer :)

I am lost . . . What is a PSP?

PlayStation Portable :) 

               Thanks. . . I'm behind the times.
