What it says about you
Opponents choose 1...c5, mostly with 2...Nc6, and you take them on in the Open Sicilian with 3.d4 instead of dodging into Rossolimo or Alapin territory. That is a confident choice, and it works: 68% over 33 games against a 60% baseline. You are more comfortable attacking the Sicilian than defending it, which is ironic given your Black repertoire.
How you play it
You come out of the opening slightly better: win chance at move 12 is 55 and at move 20 it is 55, both above your 53/52 baseline, with only 0.12 early errors per game and 576 seconds left at move 10. Conversion is solid at 19 of 24 (79%). The cracks are in the middlegame. All 7 classified non-endgame losses came there, 4 of them from big positional errors, and blunders run at 0.88 per game, above your 0.77 baseline. The Open Classical (…d6 lines) has come up 4 times at 62.5%.
What you're missing
- 01
King safety prophylaxis: twice the engine wanted Kh1 (instead of 16.Bxh6, 46% to 26%, and instead of 19.Qe2, 53% to 13%). In Open Sicilian middlegames with Be2 and O-O, the g1-a7 diagonal and back-rank tactics are live, and Kh1 is often the key quiet move.
- 02
Pawn grabs on the queenside: 16.Bxa7 instead of b4 collapsed a 68% position to 9% through an opponent combination. Taking on a7 in Sicilians is a classic way to get a bishop trapped or a file opened against your own king.
- 03
Positional drift: 4 of the 9 losses were labelled big positional errors, and 26.Rxa5 instead of h3 (35% to 10%) is the same problem. You grab or trade when a luft or consolidating move was needed.
- 04
Your blunder rate is 0.88 per game, the highest of any opening you do well in, even though you are still over 460 seconds on the clock when these errors happen. This is about attention, not time.
How to improve it
- 01
Against 2...Nc6 lines that reach the Classical (5...d6), play 6.Bg5 (Richter-Rauzer) and aim for Qd2 and O-O-O. That gives you a clear attacking plan instead of the slower Be2 and O-O setups where your prophylaxis leaks show up.
- 02
Against the Sveshnikov (4...Nf6 5.Nc3 e5 6.Ndb5 d6), the 7.Nd5 line and the 7.Bg5 a6 8.Na3 b5 9.Nd5 line both give you a stable d5 bind with c3 and Nc2-e3. That suits your positional edge better than messy 9.Bxf6 lines.
- 03
If you castle short, make Kh1 or a timely h3 part of your standard development checklist before launching f4. Two of your four recent mistakes were exactly that move.
- 04
Treat a7 and b7 pawn grabs as guilty until proven innocent. Check whether ...b6, ...Ra8-a-file pressure or a queen check can trap or punish the piece before you take.

Next steps
Add Kh1 to your checklist
In every short-castled Open Sicilian, ask on moves 14-20 whether Kh1 or h3 is needed before any active move.
Review the Bxa7 disaster
Go through the 16.Bxa7 game with an engine and write down the combination you missed. It is the template for that kind of trap.
