Definition
K plus P vs K is the most important endgame for T2 Club players. Win or draw depends on opposition ownership. If attacker's king is in front of pawn with opposition, wins. If pawn is too advanced or king lags, typically draws.
Core Ideas and Principles
Core principles: (1) winning king must be in front of pawn, (2) winning king has opposition (kings facing at odd distance, opponent to move), (3) pawn behind king as tempo reserve. If opponent king can keep opposition in front of pawn, result is draw (player must push pawn too early or lose opposition).
Key Move Sequence
Winning example: 1...Kd7 (black loses the opposition) 2.Kf6 Ke8 3.e5 Kf8 4.e6 Ke8 5.e7 Kd7 6.Kf7 (the white king guards the promotion square) Kd6 7.e8=Q wins. Drawing example: if the black king keeps the opposition in front of the pawn, White has to push the pawn first, the black king blockades the promotion square and the game is drawn.
Common Mistakes
- 01Mistake
Push pawn too early before king is in front. This permanently loses opposition.
CorrectionBring king in front of pawn first (up to rank 6 or 7), then push pawn. If king is not yet in front, pushing pawn only worsens the position.
- 02Mistake
As defender, king moves from e-file to f-file or d-file, opening pawn's path.
CorrectionDefender: keep king on pawn's file. If attacker pushes pawn, retreat king to rank that keeps opposition. This is the basic K plus P vs K defense; the Philidor name belongs to the rook plus pawn vs rook endgame.
