Hi Jeffery!
Quick Snapshot
Peak Blitz Rating: 3192 (2025-06-24)
Recent form: 6-game winning streak in Chess960 on 06-Jun, but mixed results in classical positions earlier in the week.
Your Competitive Signature
You consistently seize space with early pawn storms (g- and f-pawns) and don’t shy away from speculative sacrifices.
In the gurelediz game you took over the dark squares straight out of the gate:
What’s Working Well
Initiative first mentality. Your willingness to throw pawns forward often puts opponents on the back foot immediately.
Tactical alertness.
Wins against Pranesh M and Hans Niemann featured clean tactical conversions once the position opened.
Energy in fast time controls. When you remain ahead on the clock, your move quality stays high. shows a clear uptick when you keep a time edge.
Recurring Trouble Spots
Time-pressure collapses. Two of your last five losses (vs Nguyen Ngoc Truong Son and Hans Niemann) happened with < 5 s on your clock while still fighting.
Over-extension in classical structures.
In the loss to Hikaru Nakamura (A01) the pawn trio …c5-…e5-…d5 left weak dark squares that were exploited after 14. Nc4.
Knight “yo-yo” syndrome. Repeated maneuvers (Na4–Nc3–Na4–Nc3 in your 03-Jun game) cost several tempi and ceded the initiative.
Endgame resilience. A materially equal rook ending vs HansOnTwitch slipped after 46…Rxb3; technique under time stress can still be tightened up.
Targeted Training Plan
Clock discipline drill. Adopt a 30-30-40 rule (opening-middlegame-finish). If you drop under 40 % of your total time before move 20, force yourself to make three instant “safe” moves to rebuild a buffer.
Centralised opening set. Add a principled 1.e4 line (Italian / Scotch) and a solid 1.d4 main line to balance your flank-pawn repertoire. One weekly deep dive with engine + model game should suffice.
Endgame refresh. Spend 15 min/day on rook-and-pawn defensive studies. Many positions from your own games are perfect material; convert them into flash-cards.
Quiet-position workouts. Twice a week, play 15|10 games focusing on keeping all pawns on their original files through move 10 unless the centre demands otherwise. This will nurture patience and reduce over-extension.
Post-mortem habit. After each session pick ONE critical moment, annotate why you chose that move, then compare with engine. Quality > quantity.
Benchmark Goals (Next 30 Days)
Average time remaining at move 20 > 50 s in 3|1 blitz.
Reduce games lost on time from 14 % → 5 %. will reflect the trend.
Score ≥ 70 % from equal rook endings in your database review.
Final Encouragement
Your creativity is world-class—harness it with a bit more structure and time control discipline, and you’ll convert many of those razor-thin losses into convincing wins. Keep the energy, add the polish, and your next 3192 (2025-06-24) milestone will arrive sooner than you think.
