Roberto Junio Brito Molina (RobertoJBM)

International Master Extraordinaire

Meet Roberto Junio Brito Molina, or as chess aficionados like to call him, RobertoJBM — a mighty International Master who has danced across the 64 squares with elegance, ruthlessness, and a little bit of flair for the dramatic! With a peak Blitz rating soaring to an astonishing 2924 (achieved in early 2025), Roberto doesn’t just play chess; he practically composes symphonies in rapid-fire fashion.

Born for speed and precision, his Bullet rating once peaked at 2902, proving that when the clock is ticking and nerves are frayed, he thrives like a caffeine-powered knight on a mission. His Rapid play, while enjoyable at a more relaxed pace, boasts a solid peak of 2349, showing versatility across all time controls.

A Career of Streaks and Strategy

With a jaw-dropping longest winning streak of 44 consecutive games, Roberto has at times steamrolled through opponents like a rook on an open file. And sure, the game isn’t always easy — his longest losing streak stands at 36 — but this IM bounces back with the resilience of a pawn ready to promote.

Roberto’s playing style is a delicate cocktail: he resigns early only 0.75% of the time (because who likes to give up?), enjoys endgames in nearly 87% of his games (the real battlefield where legends are made), and maintains a White win rate of 53.88% — just enough to keep his opponents guessing and his fans on the edge of their seats.

Top Opening Choices

  • Top Secret — a mysterious repertoire that encompasses 19,381 blitz games with an almost 50% win rate. What’s the secret? Only Roberto knows...
  • Colle System — a humble opening that sneaks in with less success, but hey, you can’t win them all!
  • Indian Game Yusupov Rubinstein System & King’s Indian Attack — favorite battlegrounds where he claims nearly half of his games with style.

The Human Behind the Moves

When not tearing up the bullet and blitz leaderboards, Roberto enjoys perfecting his comebacks — with an impressive 86.17% comeback rate after losing a position. Forget superheroes, this IM has a chess cape sewn with determination!

His best time to play? The witching hour around 3 AM, where every pawn push and knight fork turns into magic. Beware opponents, as his victory often arrives when others are counting sheep.

Recent Showdowns

In recent battles, Roberto has:

  • Triumphed over formidable opponents like ReyEnigma and Pencil-in-a-bar, charming the crowd with strategic finesse.
  • Faced tough losses too — including a challenging game against Pencil-in-a-bar — reminding us that even legends have humbling moments.
Here’s a taste from his latest win — a thrilling encounter where he capitalized on the Dutch Defense Fianchetto Attack with powerful precision and sealed victory as his opponent resigned at move 39.

Whether you call him Roberto or RobertoJBM, one thing’s for sure: this International Master’s journey through chess is a tale of passion, grit, and relentless pursuit of checkmate glory. Keep your eyes peeled — you never know when he’ll strike next!

What you do well in blitz

Your blitz play shows a strong willingness to fight for activity and lines opened by piece play. You tend to keep the initiative when your opponent overextends, and you’re not afraid to complicate positions to create practical chances. In middlegame battles, you often find ways to re-coordinate pieces and pressure key squares, which leads to opportunities to swivel into a favorable endgame or win material when a tactical sequence appears.

  • You actively seek dynamic chances and don’t shy away from sharp lines when they arise.
  • You manage to defend tough positions and avoid immediate collapses in the heat of the clock.
  • You convert a few chances into wins by maintaining pressure and coordinating rooks and minor pieces effectively.

What to improve for stronger blitz results

  • Time management: in blitz, avoid spending excessive time on early tactics. Build a simple plan for the first 8–12 moves and stick to it, then use the remaining time for concrete calculations in critical moments.
  • Conversion of small advantages: when you gain a micro-edge, aim for a clear, practical plan to increase it (e.g., activate the king in the endgame, place rooks on open files, or force a liquidation that leaves you with a drawn or winning endgame).
  • Endgame technique: practise rook endgames and basic pawn endings. In many blitz games, you’ll reach simplified endings; a few reliable patterns (rooks behind passed pawns, king activation, using opposition) can convert draws into wins or save losses from worse endings.
  • Tactical pattern recognition: daily short tactics practice (10–15 minutes) focused on common motifs such as back-rank weaknesses, forks, discovered attacks, and typical defences to threats you’ve seen in your games.
  • Opening discipline: cultivate a compact, reliable 2–3 opening choices with clear middlegame plans. This reduces early drift into uncomfortable positions and gives you clearer routes to play in blitz. Consider reinforcing the Slav Exchange, Caro-Kann Exchange, and a flexible Queen’s Pawn system as practical anchors.

Opening and game plan guidance

From your recent games, you’ve shown willingness to enter open lines and tactical melees. To sharpen results, solidify two to three openings and study their typical middlegame ideas so you can switch to a clear plan rather than guessing on move 10–12. For reference, you can explore these common choices in your repertoire:

  • Slav Defense with the Exchange Variation, which often leads to stable pawn structure and clear rook files to contest.
  • Caro-Kann Defense with the Exchange Variation, yielding solid piece development and chances to break in the center under controlled conditions.
  • A flexible Queen's Pawn setup (e.g., London System family lines) to keep a steady, positional middlegame and avoid sudden tactical shocks.

Recommended reading targets include material on the Slav Defense, Caro-Kann Defense, and Queen’s Pawn systems. See placeholders for quick reference: Slav Defense and Caro-Kann Defense.

Practical plan for the next week

  • Choose 2 openings to deepen (one dynamic, one solid) and study 6 model games for each, focusing on typical middlegame plans.
  • Do 10–15 tactical puzzles per day, with emphasis on patterns you’ve encountered in your blitz games.
  • Play 20 blitz games with a strict time plan: limit deep over-calculation in the first 12 moves, then use the remainder to decide the best practical plan and execute it.
  • After each game, write down the critical moment and one concrete improvement you would apply next time.

Progress snapshot (for your reference)

If you want, I can tailor a 2-week training plan around your upcoming games. You can also share a couple of your latest games in PGN, and I’ll annotate them with concrete, move-by-move improvements. Roberto Junio Brito Molina
