promoted and thus be a valuable asset. Almost all promotions occur in the endgame, but promotion can happen at any point in the game. Despite the pawn being a weak piece, its ability to be promoted increases its value; as a result, having an extra pawn can often be a decisive advantage. In general, a pawn is more valuable the farther advanced it is, as it is closer to promotion. As a result, it is often beneficial to place a pawn in enemy territory; even if it does not control any important squares, it may still be useful, as it forces the opponent to ensure that it is not promoted. A passed pawn is a pawn that no enemy pawns can stop from reaching promotion. A passed pawn is highly valuable in the endgame, where few enemy pieces remain to prevent it from being promoted. A is a situation in which each side tries to promote a passed pawn before their opponent. Usually, the first player to promote wins unless their opponent can promote immediately afterward. Examples Opening promotion Promotion occasionally occurs in the opening, often after one side makes a blunder, as in the Lasker trap, which features a promotion to a knight on move seven: 1. d4 d5 2. c4 e5 3. dxe5 d4 4. e3 Bb4+ 5. Bd2 dxe3 6. Bxb4 exf2+! 7. Ke2 fxg1=N+! Schlechter–Perlis, Karlsbad 1911 could have featured a promotion to queen on move 11: 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. e3 Bf5 5. Qb3 Qb6 6. cxd5 Qxb3 7. axb3 Bxb1? 8. dxc6! Be4?? 9. Rxa7! Rxa7 10. c7 Threatening both 11.cxb8=Q and 11.c8=Q. Perlis avoided the trap with 8...Nxc6!, losing more slowly. The British grandmaster Joe Gallagher used the same tactical pattern a half-move earlier in Terentiev–Gallagher, Liechtenstein Open 1990: 1. d4 Nf6 2. Bg5 Ne4 3. Bf4 c5 4. c3 Qb6 5. Qb3 cxd4 6. Qxb6 axb6 7. Bxb8? dxc3 8. Be5?? Rxa2! And now White could have resigned, since if 9.Rxa2, ...c2 promotes the c-pawn. In the actual game, White played 9.Nxc3, dropping a rook, and played on in a hopeless position for several more moves. Another example occurs after the moves: 1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Ng3 h5 6. Bg5 h4 7. Bxf6?? hxg3 8. Be5 Rxh2! 9. Rxh2 Qa5+! 10. c3 Qxe5+! 11. dxe5 gxh2 With
