Practice the Philidor Defense in Exchange, Hanham, and Steinitz lines, plus the Counter-Gambit. Use our Philidor Defense guide alongside 8 guided lines, 16 exercises, and six starting positions for games against the bot.
Eight lines, one at a time: you play Black in four and White in four. Step through the moves and use the line idea to see why each branch exists. Finish a line and its checkmark stays in your browser.
Keyboard: ← → step through the moves. Click any move chip to jump.
Where the moves come from: every line and position in this trainer comes from our Philidor Defense guide.
Solve central captures, developing moves, pawn breaks, and tactical replies. Every line from Learn appears at least twice, and each wrong answer is a legal move from the same board position.
Keyboard: Enter next drill · H hint · R reset the position.
You hold the Black pieces in the book starts and switch to White only for the Legal's Mate set piece. Practice compact development, timely breaks, and the forced finish.
Six positions cover the main setup, four book branches, and Legal's Mate.
Three directions, each with a reason. Everything below links to a page that exists today.
