The Lucena Position: White to play and win
How it works
I
Learn the idea
A two-minute lesson on the one concept that decides the position: the opposition, the bridge, the third rank.
II
Beat perfect defense
Play it out. The opponent pushes its pawn to the last rank, sets traps, and never, ever gifts you the win.
III
Keep it forever
Positions you missed come back, mirrored and color-swapped, so you revisit the idea, not the squares.
