showing how to lose by playing so poorly with its strategy.

It promises:

 
"Checkers - Practice here, then obliterate your friends   Play » "   

I do like:

1) the looks of ithe board and pieces
2) how to click the pieces to move
3) the speed at which it returns a move
4) apparently it plays by the correct rules of checkers/draughts

Can you amend it or substitute it with a different
computer checkers game to improve at least
novices' skills, please?
