Popularity rank #62 of 64 · Endgame Pro defence · against Ruy Lopez

After ...fxe4 Black often has a pawn on e4 or e5 and a half-open f-file. White's d3 or d4 pawn decides how open the centre gets.

Watch out: Black's king is a little exposed after ...f5. Watch for Qh5+ and checks on the e8-h5 diagonal, and do not leave the king in the centre for long.

A chess trainer that remembers what you missed

Most games between club players are decided by a short tactic — a fork you didn't see, a pin you walked into, a back rank you forgot to air out. Endgame closes the loop: learn the pattern on the Path, use it against a bot, get graded, and drill the miss until it sticks.
