Clean London against ...Nf6, until four moves in a row go wrong.
1. d4 Nf6 2. Bf4
Your opponents choose 1...Nf6, and you answer with an immediate 2.Bf4, keeping your London the same no matter what Black does. You clearly prefer structure to theory. That is efficient, but it also means your preparation stops at move 3.
This is the cleanest opening you play. Early errors are 0.26 per game, blunders are 1.10 against your 1.22 baseline, and your win chance is 54.8 at move 12, well ahead of 52.1. You play the first 10 moves quickly (167s left). Only 5 of 81 decided losses happen in the opening, while 65 happen in the middlegame. The main line scores 50.9%, the ...O-O line 82.1% over 14, but the East Indian (...g6, ...O-O) only 22.7% over 11 games. Recently you have scored 45.0% over 20 games.
Last 90 days: 20 games, 45% score.
Middlegame collapses: in one recent game you went from 93 to 9 over moves 19-22 (Nh7, Nf7, Bxf5, Qe2+), and the engine wanted Qa4 three times in a row. Once things started going wrong you did not stop and look for the simple queen move.
The East Indian London setup (...g6, ...Bg7, ...O-O) scores 22.7%. The fianchetto bishop on g7 targets b2 and d4, and your standard London does not handle it well.
Hung pieces (21) and missed tactics (21) are your top loss causes, and 40 losses were timeouts. The opening is not the problem.
You won 93 of 149 games from 85%+ positions (62%). That is better than average, but a third of your winning games still slip away.
Against ...g6 and ...Bg7, many strong players switch to Nc3, Qd2, Bh6 and e4 (the '150 Attack' style) instead of e3 and c3. That aims straight at the fianchetto and gives Black less time to target b2.
If you keep the London against ...g6, play h3 so ...Nh5 does not trade off your Bf4, and meet ...c5 with c3 so b2 is protected. Avoid Ne5 before Black has committed.
When you notice you are knight-hopping (Nh7, Nf7), stop and look for a queen move that forces something. Your queen was the move in all three missed positions.
Work on middlegame tactics rather than opening theory, since that is where 65 of your 81 decided losses happen.
