A king hunt in chess refers to a strategic pattern where the opponent’s king becomes vulnerable and is relentlessly pursued with a series of check moves. At times, the king is lured away from its initial position and eventually cornered in hostile territory, leading to checkmate.
One way to gain tempo is by simultaneously developing a piece and delivering a check. However, if the opponent can counter the check by developing their own piece, the overall effect may be neutral. On the other hand, if the check can be blocked by a beneficial pawn move that also forces the checking piece to retreat, it is possible to even gain an advantage by losing a tempo.
A clearance sacrifice is a tactical maneuver in chess where a player willingly sacrifices a piece or pawn in order to clear a particular square or line for another piece’s activity. The sacrificed piece is typically blocking the path of a more valuable piece or preventing a tactical sequence from unfolding.
