Endgame tactics: Lucena position (free pdf, video, lichess.org link to practice)
The Lucena position is the most famous endgame position. It is as follows. It is winning for white (with a pawn and a rook vs a rook), but only if white knows what they are doing. I give you the position and some goodies: A free pdf with 5 pages…
Puzzle 2. End-game. Rook vs pawn. White or black wins? or perhaps a draw?
Have a look at this position. Black just checked the white king with the rook. Is it black winning because of the rook? Is it white winning because the position is too close to promotion? Or is it a draw, and how exactly? Have a look and think about it!
