Chess Opening Theory/1. e4/1...e5/2. f4/2...d5/3. exd5/3...e4
After giving the pawn on d5, the e4 square is now free so Black pushes the e pawn instead of taking on f4. The idea is to ruin White's plan of opening the f file. The e4 pawn will also be quite a nuisance for White as it prevents natural development of the knight on f3. White will thus try to get rid of this pawn as soon as possible.
