Your most common line

1. c4

What it says about you

You pick 1.c4 now and then, probably to escape the Englund Gambit and the other annoying 1.d4 replies, or just for variety. It's a sign you enjoy exploring. But your English has no fixed shape: there is no repeated main line, so every game becomes improvisation.

How you play it

You start reasonably (move-12 win chance 53.5) and then fall back (move-20 win chance 48.8). The position deteriorates from move 12 to 20, and you score 34.4% (5-10-1). Six of your 8 decided losses came in the middlegame, and games run 40.9 moves. You convert only 4 of 9 winning positions. The endgame slips (45.Rf5+, 46.d5, 48.Kd5) all came with 12 to 10 seconds left.

What you're missing

  1. 01

    21.Kc2 walked into mate (46% to 0%) when Ke2 was safe. You made a king move without checking the opponent's checking lines.

  2. 02

    Your late endgame collapsed: 45.Rf5+ (82% to 53%), 46.d5 (52% to 14%) and 48.Kd5, which hung a rook (82% to 49%), all under 13 seconds.

  3. 03

    There's no variation data or recurring main line, which means you have no English repertoire and are reinventing the opening every game.

  4. 04

    move-20 win chance at 48.8 drops below move-12 win chance at 53.5, the clearest sign your middlegame plans in English structures aren't working.

How to improve it

  1. 01

    If you keep it, commit to one system, such as 1.c4 e5 2.Nc3 Nf6 3.g3 d5 4.cxd5 Nxd5 5.Bg2 followed by Nf3, O-O, d3, Rb1 and b4. The queenside minority push is the whole plan.

  2. 02

    Against ...d5 setups, fianchetto and pressure d5 with Bg2, Nc3 and cxd5, then attack on the queenside rather than the kingside.

  3. 03

    For rook endgames under 15 seconds, keep the rook active behind passed pawns and avoid king walks near the enemy rook.

  4. 04

    Honestly, the best plan might be 1.Nf3 with 2.d4 into your London. It sidesteps the Englund and keeps your good structure.

Next steps

01

Park 1.c4 for now

At 34.4% it costs you points. Use 1.Nf3 followed by d4 if you want to avoid 1.d4 sidelines.

02

If you keep it, pick one system

Commit to the g3, Bg2, Rb1 and b4 plan in every English game so you stop improvising.

03

Check king moves for checks

Before any king move, list all of the opponent's checks. 21.Kc2 allowed mate.
