Frontal checks are rook checks given from in front of the enemy king, facing the direction in which it is moving, as opposed to checks given from behind. Frontal checks are rook checks given from in front of the enemy king, facing the direction in which it is moving, as opposed to checks given from behind. In rook endings, a rook can check the enemy king from different directions. A check from behind comes along a file from far back on the board, behind the king and its pawn. A frontal check comes from the rook standing in front of the king, on the same file, facing the direction the king is heading. The difference is practical. A rook that checks from in front is close to the enemy pieces and can be hit by the king or covered by a pawn. After a frontal check the king often steps toward the rook or behind a shelter, gaining time. A check from behind keeps the rook far away, and the king cannot approach it, so the checks can continue for many moves. For this reason the defending side usually checks from behind in endings such as the [Philidor position](https://georgelichess.com/glossary/philidor-position.md), where the rook goes to the back rank and checks as soon as the pawn reaches the sixth rank. Frontal checks are not always bad, because they can force the king away from a good [square](https://georgelichess.com/glossary/square.md) or win a tempo, but they only work when the rook stands far enough away that the king cannot simply walk up to it. A typical [mistake](https://georgelichess.com/glossary/mistake.md) is to start giving checks with no plan. Each check should either drive the king away from a useful square or win time to improve the rook. Before you check, ask yourself where the king will go and whether your rook will then be in danger. Also called: checks from behind and in front. ## Example position Black to move can play Rd8, a check from in front of the White king, while a check along the same file from d1 would come from behind it. Position (FEN): `r5k1/8/8/3K4/8/8/8/8 b - - 0 1` Also worth reading is [Checking distance](https://georgelichess.com/glossary/checking-distance.md). Checking distance is the space a defending rook keeps from the enemy king, usually a long way off, so it can give a series of checks from the side or behind without being attacked. Also worth reading is [Short side](https://georgelichess.com/glossary/short-side.md). The short side is the side of a pawn's file that has fewer files between it and the edge of the board, the opposite of the long side where more room is available.
