Angel Arribas Lopez: The Grandmaster’s Journey

Angel Arribas Lopez, also known in the chess world as FatUpss, has earned the coveted title of Grandmaster from FIDE — a distinction reserved for those who see the 64 squares as a battlefield for tactical wizardry and strategic brilliance. With a career packed with both explosive wins and humbling defeats, Angel’s story is as fascinating as a Ruy Lopez opening against a well-prepared opponent.

From Rapid Bluffs to Bullet Barrages

Beginning their rapid rating journey at 1200 in early 2017, Angel quickly climbed to a peak of 2543 in July 2020. This rapid rating rollercoaster reflects a player constantly evolving their game. More impressively, Angel’s blitz play reached an astonishing peak rating of 2940 in October 2021 — a realm where only the fastest and sharpest brains survive. Not to be outdone, their bullet peak rating touched 2774 in August 2017, showcasing lightning-fast reflexes and ruthless precision.

Winning Streaks and Strategic Brilliance

With a longest winning streak of 57 games and currently riding a sizzling 31-game winning streak, Angel demonstrates the killer instinct of a true champion. Their wins outnumber losses dramatically across all formats:

  • Rapid: 227 wins, only 16 losses
  • Blitz: 622 wins, 391 losses — a war zone of calculation!
  • Bullet: 1026 wins, 760 losses — speed chess with no mercy

Even when losing a piece, Angel’s tactical prowess shines with a 55.44% win rate after such setbacks — talk about turning lemons into checkmates.

The Openings Arsenal

Angel plays their openings like a chess ninja with a Top Secret opening boasting an 86% win rate in rapid games over 257 encounters. Other trump cards in the repertoire include the Bishops Opening, French Defense variations, and the ever-poised Giuoco Piano — all wielded with perfect precision (100% win rates in their limited outings).

Psychological and Playing Style Quirks

Ever the gamer aware of their mental state, Angel has a relatively low "tilt factor" of 8, which means they can handle defeat better than most — except maybe when losing to “the” (yes, their opponent named just “the” has an unfortunate 0% win rate against Angel). Their beloved time to hunt opponents down is early morning around 8 AM — perfect time for coffee and crushing kings.

Unforgettable Matches

Among many thrilling encounters, Angel's recent victory against mcheesycheese in a Daily (correspondence-style) game was a textbook example of surgical precision culminating in a classic checkmate with Queen and knight finesse in a Giuoco Piano Four Knights Game. You can relive the magic here.

In a Nutshell

Angel Arribas Lopez is not just a name on the leaderboard but a relentless force across all chess formats — from slow and steady daily matches to blistering bullet duels that defy human limits. If you ever find yourself facing FatUpss, be prepared for a strategic avalanche combined with a dash of unpredictability and a sprinkle of sheer brilliance. After all, they didn’t become a Grandmaster by accident — it’s all part of a master plan, secretly executed over many games and countless hours in front of the board.

Feedback for Angel Arribas Lopez

Angel, reviewing your recent games reveals several positive aspects and areas for improvement that can help you progress further:

Strengths

  • Opening Choices: You show a willingness to play classical and solid openings such as the French Defense and Giuoco Piano. This helps build a strong positional foundation in your games.
  • Calculation and Attacking Instincts: You have demonstrated sharp tactical awareness, including delivering checkmates in complex positions. For example, your final moves in games show good use of queen and rook coordination to finish the game.
  • Castling and King Safety: You consistently castle early, improving king safety and enabling you to connect rooks quickly.

Areas to Focus On

  • Opening Fundamentals: In some games, early pawn moves like 3.f3 in the French Defense or allowing early queen attacks cost you material or time. Work on understanding mainline theory and typical plans for your chosen openings. This will help you avoid falling into early traps or losing tempi.
  • Piece Development: There were moments when your piece coordination was suboptimal, particularly during exchanges or when responding to opponent threats. Prioritize developing your minor pieces to active squares and coordinating them harmoniously before launching attacks.
  • Defensive Awareness: Some losses came from not adequately addressing opponent threats. After your opponent creates tactical pressure (like queen checks or threats), consider if you can simplify or neutralize threats more effectively through timely exchanges and improved piece placement.

Suggestions for Training

  • Review the basics of your preferred openings, focusing on common tactical motifs and strategic aims.
  • Practice puzzles that emphasize defense and counterattack, helping you spot threats faster and respond confidently.
  • Spend time analyzing your losses to understand critical moments where the balance shifted, especially in the middlegame.
  • Try to maintain consistent time usage to avoid rushed decisions, especially in the opening moves and key tactical moments.

Keep up the hard work and enjoy your games! Improvement is a journey, and focusing on these points will take your play to the next level.
