Hi Ben, here is some quick, data-driven feedback from your latest blitz session.
What’s already working well
- Opening breadth. You comfortably switch between the Nimzo-Indian (E36), QGD Exchange (D35) and the Najdorf/Dragadorf (B94/B90). This keeps opponents guessing and often earns you an early lead on the clock.
- Practical decision-making. Your most recent win against Attack_156 showed excellent “keep the pieces on” technique: 18…Nd4! and 19…Rc2! converted pressure straight into material.
- Creating counter-play when worse. Even in the loss to Daniel Naroditsky you found 42…Nh3! and set real mating tricks – good fighting spirit.
Recurring issues worth fixing
-
Time-management. Four of the last six losses featured time forfeits or <3-second scrambles from equal positions.
➜ Action: Add 10-minute “clock-only” drills (move instantly when ≥30 s; think only when <30 s). After two weeks, splice in to verify improvement. -
London-system frustration. Your 0-1 loss (D02, 1 d4 Nf6 2 Nf3 d5 3 Bf4…) follows a pattern:
- …c5/…Qb6 grabs a pawn but leaves …c4 + weak dark squares.
- Missing the thematic break …e5 when White’s queen is still on c1/c2.
-
Kingside pawn storms in the Dragadorf. In the defeat by The_Berserk_Musketeer you allowed 17.g4-h5-h4 with zero counter-punch on the queenside.
➜ Action: Adopt Najdorf main-line 6…e5 or, if you keep 6…g6, memorise the forcing sequence 11…b4 12.Nd5 Nxd5 13.exd5 Na5 14.Qxb4 Bd7! holding the dark squares. -
Endgame conversion vs. passed pawns. The London loss ended with 36…Rc8?! allowing the b-pawn to reach b6-b7-b8. Similar story in the A07 game (h-pawn break).
➜ Action: Daily 15-minute session on rook-and-pawn vs. passed pawn endings. Use the “side file passer” theme in 3-5 positions until you can win/draw under 20 seconds per attempt.
Illustrative Micro-Tactic
The engines suggest a quiet 20…a5! (freezing the pawn chain) instead of 20…Ne4?!. Worth adding to your rehearsal file.
Training dashboard
- Peak blitz rating: – aim to beat it after the next Arena Kings.
- Opening focus for June: Anti-London + Najdorf g6.
- Weekly review target: 5 wins, 3 losses fully annotated with at least one highlighted Zwischenzug.
Motivation corner
You’re scoring 70 % in games that reach move 35+. Once the clock issue is under control, your overall win-rate should climb sharply. Keep the energy high and let’s make the late-game your signature strength!
Good luck in the next Arena Kings! – Your digital second
