Andrea Ortez (AurumO) - Woman International Master

Meet Andrea Ortez, a fierce chess warrior who proudly holds the title of Woman International Master from FIDE. Andrea isn’t just another name on the chessboard; they’re a strategist with a personality as dynamic as their game. Known in the online circles as AurumO, Andrea combines a solid understanding of the game with a touch of flair—and a healthy dose of humor.

Career Highlights & Style

Andrea’s rating journey is a rollercoaster of thrilling triumphs and dramatic battles. Their peak blitz rating soared to an impressive 2148 in early 2023, proving lightning-fast reflexes aren’t just for flash chess players. When it comes to bullet games, Andrea reached a peak rating of 2049, showcasing the ability to checkmate while barely blinking.

Their playing style is as clever as a knight’s fork: with an 83.86% frequency of endgames and a comeback rate of about 86.53%, Andrea can bounce back from setbacks, turning near-defeats into victories. Opponents beware—the WIM has a 47.43% win rate even after losing a piece, which means that giving Andrea material advantage might not be the best idea!

Stats to Brag About

  • Blitz Record: 1366 wins, 1259 losses, 174 draws—because even legends have off days.
  • Bullet Record: 959 wins, 883 losses, 88 draws—speed chess with no mercy!
  • Rapid Record: 43 wins, 31 losses, 2 draws—slow and steady doesn’t apply here.
  • Daily Chess: 1 win, no losses, and a draw—guess they take relaxing games seriously too.

Not Just a Player, But a Time Lord

Andrea plays best at 1 PM sharp—when tactical awareness peaks. The best hour to challenge AurumO? Possibly not 1 PM, because that’s when they shine brightest. Studies show their most successful hours are actually early morning and late night too, proving chess is a 24/7 passion.

Opening Mysteries & Opponent Woes

Andrea’s opening moves are mostly "Top Secret." With a nearly 50% win rate against a difficult assortment of opponents, many would love to crack their opening strategy code. Amongst the most frequent victims are players like davo105 and zetitasaurio. Let’s just say some opponents have a love-hate relationship with AurumO!

Recent Memorable Encounters

Their latest hard-fought victory involved a swift resignation from the opponent after 22 moves in a beautiful Alapin Sicilian Defense. Even when tides turn, Andrea’s resilience is well-documented, although the occasional loss reminds us that even champions have to recharge.

Fun Facts

Long winning streak: 12 games (because sometimes the stars align).
Longest losing streak: 14 games (because life’s not always a fairy tale).
Average moves per win: About 71 moves - patience is a virtue, especially in chess.
And a tilt factor of 14 - so yes, Andrea gets frustrated too, but quickly bounces back with a grin (and a sneaky bishop move).

"Chess is life, but sometimes you just have to resign graciously and come back stronger." - Probably something Andrea would say.

General Overview

Andrea, your recent games reveal a strong competitive spirit with several impressive wins. You have maintained a solid performance with a strength adjusted win rate near 49.5%, reflecting the ability to hold your own against similarly rated opponents. Your rating changes over past intervals demonstrate growth, particularly the positive trend this past month with a +10 rating gain and a positive slope in the last month and twelve months overall.

Recent Game Highlights

  • Your wins show good familiarity with Sicilian Defense variations, especially the Rossolimo Fianchetto Gambit and Alapin Sicilian. You effectively leverage central control, piece activity, and tactical motifs to pressure opponents.
  • Several victories involved active piece play, especially in open positions, capitalizing on opponents' weaknesses and creating decisive threats.
  • In winning the game against japonia125, for example, your knight outposts and queen activity highlighted strong tactical awareness and positional assessment.

Areas for Improvement

  • Time Management: Some losses occurred due to running low on time. Improving pace, especially in complex positions, could prevent time pressure and blunders.
  • Endgame Technique: A number of your losses happened in simplified positions or endgames, e.g., games against vincentbahelalfonso and silverain29. Working on theoretical and practical endgame knowledge will help convert close games or salvage difficult ones.
  • Opening Consistency: While you have a good grasp of Sicilian structures, varied opening choices have led to mixed results. Solidifying a more reliable repertoire and studying thematic pawn structures could boost your early game stability.
  • Defensive Awareness: Several games showed missed defensive resources or vulnerability to pins and forks in the middlegame. Practicing tactical puzzles focusing on defense and calculation under time pressure would be beneficial.

Rating Trends and Next Steps

Your 1-month rating gain and positive recent trend indicate you're on an upward path. The small dips over longer periods suggest occasional setbacks, but your overall trajectory is promising. To continue your progress, consider:

  • Consistent study of your opening lines, focusing on key plans and common traps.
  • Dedicated endgame practice to improve technique and confidence.
  • Timed tactical training to enhance your calculation speed and time management under blitz conditions.
  • Analyzing your losses in detail, especially those on time or with tactical oversights, to identify recurring patterns.

Final Encouragement

Keep pushing forward, Andrea! Your recent successes show you have the skills and potential. Refining the areas mentioned and maintaining a steady study and practice routine will help you climb steadily in your blitz games.
