White starts by playing 1.e4 (moving his king pawn two spaces). This is the most popular opening move and it has many strengths—it immediately works on controlling the center, and it frees two pieces (the queen and a bishop). The oldest openings in chess follow 1.e4. Bobby Fischer rated 1.e4 as "Best by test." On the downside, 1.e4 places a pawn on an undefended square and weakens d4 and f4; the Hungarian master Gyula Breyer melodramatically declared that "After 1.e4 White's game is in its last throes." If Black mirrors White's move and replies with 1...e5, the result is an open game.
