I edited the example in the page two one that I see as better because:

1) both rule are required to come to a conclusion, and so 'inference' is truly required

2) it seems less open-ended/ambiguous to ask 'what color is fritz' than 'what is fritz'

3) these rules seem less contrived to me

Further edits (15th May 2006):

I added a similarly long explanation of the workings as there is for Backwards chaining.

I made only the first reference to 'frog' a wiki-word, but am still unsure whether even this is neccesary - who doesn't know what a frog is, and even then, how would that relevant to the example; Fritz might as well be a jabberwocky! (or jubjub bird etc.)

It would also be nice to expand on the 'dynamic' point, as I'm not sure it is that clear.

Finally, Both backwards *AND* Forwards chaining pages note that these methods are often used in expert systems; is this a contradiction?
