Roberto Assumpcao - FIDE Master

Meet Roberto Assumpcao, the chess virtuoso who has earned the prestigious title of FIDE Master, a badge of honor from the international chess federation. Roberto, also known in the chess world as Assumpcaos, has been conquering the 64 squares with a swift blend of tactical brilliance and psychological resilience — well, most of the time.

Starting as a modest rapid player with a humble 1995 rating back in 2020, Roberto didn’t stay there for long. By 2021, the number spiked dramatically to over 2400 in rapid games, reflecting an intense hustle and a serious upgrade in skills. Blitz is also a playground where Assumpcaos flourishes — with peaks past 2300 Elo and an aggressive playstyle that sometimes burns opponents faster than a lightning bolt (pun intended).

Roberto’s style is like a good mystery novel: sturdy and long, with an average of around 74 moves per win in rapid games, meaning you’re in for a thrilling ride if you face him. With a comeback rate of 87% and the incredible ability to win every single time after losing a piece (no pressure, right?), Roberto keeps opponents on their toes. A tilt factor of 12 is low enough to show that frustration is for mere mortals.

When it comes to openings, Roberto has a secret weapon—hundreds of games under the belt with a mysterious "Top Secret" opening line that boasts around a 52%+ win rate in rapid and an even snazzier 53%+ in blitz. Opponents beware: “Top Secret” might just be the code you never want to crack.

Though on some days the bullet rating whispers humbly (~1800 max), it’s clear Roberto prefers to take a calculated tour through the rapid and blitz circuits, where wins and draws stack up like trophies. He currently sports an impressive all-time blitz win record of nearly 7000 games, proving stamina and dedication.

Off the board, Roberto’s psychological edge shines in his almost perfect comeback rate and 100% win rate after losing a piece. That’s like getting knocked down and then putting on a boxing clinic. It’s safe to say Roberto could teach a masterclass in “Losing a piece but not losing the game.”

So, whether you catch him at 6 AM (his highest win rate hour—humble brag), or on a Thursday afternoon, challenge him if you dare. Roberto Assumpcao’s chess journey is a testament to grit, surprises, and a little chess magic wrapped up in a FIDE Master’s title.

Fun fact: Roberto’s longest winning streak hit 13 games, proving that once he’s on fire, even the Grandmasters better watch out!

Hi Roberto!

Great job maintaining a high win-rate against strong opposition. Below is feedback distilled from your last dozen rapid games.

Your Key Strengths

  • Creative attacking play. The 38-move win over Artur Farias Lopes featured a model rook-lift (Rh3–g3–g1) and the instructive queen sacrifice sequence 33.Qh5 a5 34.R1g2… 38.Qxh7# – a nice illustration of coordination. (

    )
  • Flexible opening choices. You handle Réti/English systems with both colors, often steering play into structures you understand well (double-fianchetto, Neo-Grünfeld, Queen’s Indian).
  • Tactical alertness in complex positions. Games vs domenico-84 and sujeetksinha1 show you pouncing on loose back-rank or uncoordinated pieces.
  • Good fighting spirit. Several wins came from worse or equal middlegames where you outplayed opponents in complications or time pressure.

Recurring Problems

  • Early pawn grabbing with Black. Losses vs gsapkarmk and punter99 share the motif …Qxb2/Qxb3 followed by tactical punishment. Ask “What is my opponent’s next move?” before taking side-pawns.
  • Handling of central tension. In the Modern Defense loss, White’s e5 Nd6 Nd4 break exploited your passive …d6–c6 setup. Review structures where …e5 or …c5 is required sooner.
  • Time management in won positions. Two defeats came by flagging from +2 or better (Catalan vs ialonsoal, marathon French endgame). Allocate time to convert, not only to build the advantage.

Opening Priorities

  1. Modern / Pirc set-ups (Black). Study model plans after 5.Bc4/5.Bb3. Aim for …d5 or …e5 breaks and beware of ♘c4/♘b5 jumps. Annotate 10-15 reference games.
  2. Anti-London & Anti-Jobava systems. Replace quick …b5 with solid schemes (…cxd4 …♘c6 …d6) so that the queen is not lured to b6.
  3. Endgames from the French Advance (both colours). Your longest games arise here; a sharper endgame blueprint will save both time and energy.

Next Steps

  • Review each loss for one critical moment and add it to a personal “Never Again” file.
  • During games, do a two-move blunder check before pawn grabs on the flank.
  • Practice spotting zwischenzug opportunities – many of your tactical wins use them; turning this into a habit will also help on defense.

Keep up the creative play, Roberto. With a bit more discipline in the early middlegame and clock, 2500 rapid is within reach!
