What it says about you

Your opponents choose the Nimzo-Indian check (...Bb4+ after c4), and you answer with Nc3 into the Three Knights Variation. It is a principled and sensible choice. You clearly enjoy the open, active positions it produces.

How you play it

You score 75% (12-4-0), your best opening, and it is holding at 71.4% over the last 7 games. The opening is your best in the data: 52.3 at move 12 and 55.9 at move 20, both well above your baseline, and this is one of the few openings where your position improves from 12 to 20. You blunder more here than anywhere else (1.19 per game against 0.91), but you still converted 12 of 13 winning positions. The Three Knights Variation O (9 games, 66.7%) and Duchamp (3 games, 100%) are your main lines.

Last 90 days: 7 games, 71% score.

What you're missing

  1. 01

    Tactics in winning positions. 25.Be4 missed 25.Qxg6 (93% down to 46%), which could have finished the game immediately.

  2. 02

    Clean trades. 12.exf6 lost a bishop in a trade (79% down to 43%) when 12.Rd1 was best.

  3. 03

    Endgame technique. 32.Ke4 (48% down to 24%) instead of 32.Kd3, and 49.Re1 missing 49.cxb4 (40% down to 19%). Late mistakes in games that were already level.

  4. 04

    A higher blunder rate. 1.19 per game is your highest, and you only get away with it because you get good positions out of the opening.

How to improve it

  1. 01

    Keep playing the Three Knights. Against 4...O-O, 5.Bg5 or 5.Qc2. Against 4...c5, 5.g3 is a sound choice. Against 4...b6, 5.Bg5 Bb7 6.e3 h6 7.Bh4.

  2. 02

    Your Bg5 habit shows up again here. Make sure you know when Bxf6 is the right follow-up, since it is the tactic you keep missing in other openings.

  3. 03

    When you are clearly better, look for the forcing move first. Qxg6 type moves against the black king are common when your queen and bishop line up.

  4. 04

    Keep the good positions simple. Since your advantage comes out of the opening, trading into a better endgame is often the easiest way to win.
