Of course in 2 days you can learn the rules. It's possible to teach someone chess in 30 minutes so I guess you can learn prolog in 2 days, limited to "primitives, means of combination, and means of abstraction". As with the new chess player won't be a good chess player you wont be that good in prolog after just two days. With 10 years experience with either programming or chess you might do better than just know the basics though
Given that the original question was asked a year ago, it would be interesting what emerald123 has learned so far. If it's possible to learn anything within two days emerald123 today must be an expert in each and everything at all.
