What it says about you

Your opponent plays 1...g6, and you answer with your standard 2.Bf4 and Nc3. You treat the Modern as just another London, which works well out of the opening. It does not work later, when Black's fianchetto gets active and you are low on time.

How you play it

You get excellent positions: a win chance of 58.5 at move 12 and 60.8 at move 20, among the best in your repertoire and well above your baselines. Yet you score only 44.6% over 46 games, with 62.5% over the last 4. You converted only 19 of 36 winning positions (53%). 14 of your 25 losses were timeouts, and early errors are high at 0.63 per game.

Last 90 days: 4 games, 63% score.

What you're missing

  1. 01

    Winning positions thrown away: you converted 19 of 36 games at 85%+. That is 17 games where your big edge came to nothing.

  2. 02

    Timeouts: 14 of 25 losses. You are spending time finding a win instead of playing the simple moves.

  3. 03

    At move 16 and again at move 18 you played Qg5 instead of Bxe7. Missing the same capture twice (79 to 56 and 80 to 50) is a sign of tunnel vision.

  4. 04

    At move 14 you played Ne4 instead of Qc4 and went from 91 to 58. At move 13 b4 instead of b3 missed a combination (56 to 35).

How to improve it

  1. 01

    Against 1...g6 with Bf4 and Nc3, a strong plan is Qd2, Bh6 to trade off the fianchetto bishop, then e4 and h4. Without the Bg7 Black's king is weak.

  2. 02

    Watch for ...c5 hitting d4 and ...Qb6 hitting b2. These are Black's main counter-chances and you should know your answer.

  3. 03

    When you have a big advantage, trade pieces rather than attacking. Your conversion (53%) is much lower than your London (75%).

  4. 04

    Check captures on e7 and f7 in these positions. Black often leaves pawns loose while castling, and you have missed Bxe7 twice.

Next steps

01

Trade when you are winning

When your win chance is over 80%, look first for piece trades. You converted only 19 of 36 winning games here.

02

Learn the Qd2 and Bh6 plan

Practise this against 1...g6 in 10 games. Removing the Bg7 is the most practical way to use your good opening.

03

Look at captures twice

Before every move, scan all captures for both sides. Missing Bxe7 twice in one game is the fix to focus on.
