Stop repeating the same opening mistakes.

NRV Chess plays you like a real opponent, stops you the moment you go wrong, and shows you why, then keeps track of every position until you get it right.

A bot that plays like people

In the opening it plays what players at your rating actually play. After that it mixes strong moves with realistic slips, so you face real mistakes to punish.

A coach that stops you

Choose whether to be stopped on inaccuracies, mistakes or blunders. You see the better move, the reply you missed, and the idea behind it, drawn right on the board.

An accuracy map of your openings

Every position you reach is logged with how well you play it, so you can see exactly which lines cost you.

Practice where you are weak

Weakness mode steers games into the positions you misplay most, and drills bring them back until they stick.
