1. e2e4  1... d7d6  2. d2d4  2... f7f5 This is not a popular option, of course. Advancing the f-pawn is one of the worst things Black can do in a defense against the king's pawn opening. But, surprisingly, it's not as bad as it looks. Let's not forget this is a rapid game—some liberties are allowed. 3. e4f5  3... c8f5  4. f1d3  4... d8d7  5. g1f3  5... g8f6  6. d3f5  6... d7f5  7. e1g1  7... b8c6  8. c2c3 Too timid. 8... e7e5 A new move.
