Rating Adventures
Justo’s journey through the blitz battlefield is nothing short of legendary. Peaking at over 2300 in Blitz, their speed and sharp instincts make opponents sweat bullets. Bullet chess? They've darted from a humble 915 to an awe-inspiring peak rating of 1908, proving resilience and rapid growth. And don't forget their rapid prowess, hitting an impressive 2147 rating in 2023, often leaving onlookers wondering if they have a second brain working overtime.
Playing Style (and a Dash of Personality)
- Average Moves per Win: Justo enjoys long, thrilling battles, averaging about 68 moves per victory, showing patience and strategic depth.
- Endgame Enthusiast: With an endgame frequency near 78%, Justo clearly doesn't shy away from the final battlefield, often squeezing wins out when it counts.
- Comeback Kid: An astonishing 83.6% comeback rate means never count Justo out—even if you thought victory was in the bag.
- One-Piece Loss? No Problem! A flawless 100% win rate after losing a piece reveals a knack for tactical wizardry and psychological toughness.
Justo may resign early occasionally (about 1.25% of the time), but who wouldn’t when you’ve pulled off some of the most dramatic comebacks on the board?
Record and Rivalries
With over 2,300 wins combined across bullet, blitz, and rapid formats, Justo has tasted more victory than defeat (though even the mighty have their off days!). Remarkably, Justo has a 22-game longest winning streak—enough games to binge-watch an entire series, but far cooler because they were all wins!
As for foes? Justo isn't shy about holding grudges (chess-style): perfect win rates against some opponents, and selectively polite losses to others. The chess battlefield is a colorful place where friendships are won and lost on the whims of the knight’s gallop and the queen’s sly strike.
When Does Justo Dominate?
Time-wise, Justo is a midday warrior and morning sharp shooter. Their best winning chances peek around 9 AM with a dazzling 75% win rate, and they’re also highly effective in the late morning hours. Although evenings are a bit tougher with win rates occasionally dipping below 50%, this just adds an air of mystery – maybe it’s when Justo trains their secret openings!

Performance Snapshot

Activity trends:
What You’re Doing Well
- Tactical Awareness – The combination 24…Bxh3! in your most recent win versus caesar_castrum68 shows sharp calculation and confidence in dynamic positions.
- Conversion of Material Edge – In several wins you simplified smoothly once ahead (e.g., the rook ending against mitaka8211).
- Piece Activity from the Opening – Your Black setups with …g6/…Bg7 against the Ruy Lopez or Center Game often leave you with well-placed minor pieces ready for counter-play.
Main Growth Areas
- Clock Management
- Four of your last five losses were on time or abandonment while your position was playable. Discipline tip: allocate a minimum time per move in the opening (≈5-10 s) and bank the extra for complex middlegames.
- Premature Pawn Thrusts on the Wing
- Early g-pawn advances (Grob, 2.g4 vs Indian Game) left dark-square weaknesses and cost you the French KIA game against chesstrainer24.
- Before pushing a flank pawn, run a quick checklist: center locked? king safe? minor pieces developed?
- Handling Solid Structures
- Positions arising from the French and Scandinavian show discomfort against static pawn chains. Study typical plans for both sides to avoid drifting.
- End-Game Technique vs Resourceful Defense
- In the Grob game you eventually converted, but allowed counter-play with 24…Nxc4+ and 28…Nc4. Drill fundamental rook & pawn endings to tighten conversion.
Opening Toolkit (Suggested Streamlining)
| Colour | Keep | Add/Refine |
|---|---|---|
| White | 1.e4 against open games; King’s Indian Attack setups | Replace experimental 1.g4 lines; prepare versus French with 3.Nd2 & 3.Nc3 branches |
| Black | Ruy Lopez Fianchetto (…g6) and Alekhine/Scandinavian | Against 1.d4 choose a single main line (Slav or …d6/…g6) and study thematic breaks (…e5, …c5) |
Concrete Action Plan (Next 4 Weeks)
- 10-minute End-Game Workout before each playing session – pick a random rook ending from a database and play vs engine until you win.
- Opening Focus
- French Defence: watch 2 short model games daily, annotate them, and replay the critical line vs engine.
- Blitz Time-Split Drill – Play three 3 | 2 games dedicating at least 30 s to moves 10-20 even if position seems simple; train the habit.
- Tactics – 30 puzzles/day, prioritising intermediate moves (zwischenzug) and mating nets.
- Review Sessions – Once a week pick one win + one loss; annotate without engine first, then verify.
Mindset Reminder
You win games with aggression, but you rise in rating by finishing them. Guard your clock as carefully as your king!
Good luck on the board, Justo – keep sharpening your tactics while tightening your foundations. See you at your next milestone!
