Philidor Defense: Exchange Variation
1. e4 e5 2. Nf3 d6 3. d4 exd4 ... 15 moves
I like math and chess and lots and lots of variants. Also, A^2 = (A - B) (A + B) + B^2. Now all you have to do is memorize the first 50 squares to show your friends you can square 3- digit numbers in your head! Help for the 40s : For 0 <= n <= 9, (40 + n)^2 = 1500 + 100n + (10 - n)^2.
