Everything here comes from our Petrov Defense guide. You are Black: learn 11 lines, drill 22 decisions, then play the bot. The Petrov meets 1.e4 directly, but its quiet positions still demand accurate move order, central control, and king safety.
Eleven lines, one at a time: eight teach the Black side and three teach the White side. Step through the moves and the board-specific note appears at the critical moments. Finish a line and its checkmark stays in your browser.

Where this comes from: every line, tactical pattern, and quoted engine number in Learn and Drill comes from our Petrov Defense guide. The trainer keeps the guide focused on the positions where a move order, central break, or king placement changes the game.
This is the board-work section. The 22 drills cover book moves, plans, traps, punishments, structure, and endgame echoes. Solve from the position, not from the move list: each answer has a concrete reason, a wrong move is marked briefly, and the two-stage help gives a board cue before highlighting the piece.
Keyboard: Enter next drill · H hint · R reset the position.
Now play it out. Pick a Petrov variation, choose a bot strength, and start from the position that matters. The coach watches for guide patterns, including the early recapture trap, the Classical c4 break, and the Nimzowitsch king race.
Six Petrov positions from the guide, each with opposing goals that make the strategic fight visible on the board.
Four directions, each with a reason. Everything below links to a page that exists today.
