Practice the Nimzo-Indian Defense in Classical, Rubinstein, Saemisch, and Kmoch variations. Use our Nimzo-Indian Defense guide alongside 8 guided lines, 16 exercises, and six starting positions for games against the bot.
Study eight guide-backed lines with no extensions: Classical play from both sides, the Rubinstein isolated-pawn structure, the Samisch doubled pawns, the Kmoch center challenge, the Leningrad pin, the Three Knights fianchetto, and the Family Fork.

Where the moves come from: every line and position in this trainer comes from our Nimzo-Indian Defense guide. The guide's five test positions are answered by Samisch ...Bxc3+ (-0.14), Classical ...Bxc3+ (-0.15), ...Nc2+ (-6.31), e3 (+0.16), and ...d6 (-0.44).
The 16 boards cover the queen recapture in the Classical, Rubinstein liquidation, Three Knights recapture, correctly timed ...Bxc3+, Samisch ...c5, Kmoch ...d5 and ...Qa5, the Leningrad queen pin, and both moves of the Family Fork. Every named alternative is legal on its exact board.

Choose one of six starting positions and set the opponent from 600 to 3000. The coach comments on eleven key moments, including the opening pin, Classical structural decision, Rubinstein liquidation, Samisch and Kmoch center strikes, Leningrad pin, Three Knights recapture, and Family Fork.
The six starts contain the main Nimzo-Indian position, book lines for the Classical, Rubinstein, Samisch, and Kmoch variations, plus the Family Fork position. Every mirrored goal names original pieces, pawns, squares, and a move deadline from Black's side.
