Zacarias M Ruben D — The FIDE Master Extraordinaire
Known on the virtual battlefield as zacachess, Zacarias M Ruben D has earned the prestigious title of FIDE Master. A master of blitz warfare and rapid strikes, Zacachess is a player who blends sharp calculation with an uncanny knack for comebacks — boasting an impressive 89.19% comeback rate after difficult positions.
A Journey Through the Ranks
Starting with a humble blitz rating of just around 1353 in mid-2015, Zacarias rocketed up to a peak blitz rating soaring over 2569 in 2024. This trajectory is anything but ordinary, showing a player who has not only mastered the Sicilian Defense Najdorf Variation (a favorite in nearly 500 games) but also consistently innovates with openings from the Scotch Game to the Bogo Indian Defense. Zacachess’s playstyle? Expect deep endgames lasting over 74 moves on average for wins, and a psychological resilience that keeps tilt far away for most of the time.
Style & Performance
Zacarias prefers the intense thrill of blitz chess, committing over 3,600 wins in this format alone, with an almost even split between wins and losses — a true gladiator at the 64 squares. Their endgame frequency is a whopping 83%, indicating ultra-staying power and strategic grinding against opponents. White moves are slightly more successful, maintaining a ~53% win rate when taking the first move, while black is no walk in the park either.
Whether racing against the clock or engaging in rapid-fire strategic battles, Zacachess exhibits a quirky blend of patience and aggression. The long winning streak maxed at 26 consecutive victories, but even the grueling 21-game losing streak couldn’t dampen their spirit. And if you wonder when Zacarias is best at their game, mornings around 9 AM seem to trigger their sharpest focus.
Favorite Openings & Quirks
- Blitz staple: Sicilian Defense Najdorf Variation — with a winning rate nudging 52%, it’s their playground.
- Rapid favorites: Scotch Game and Nimzo-Indian Defense bring a 100% win rate in limited clashes — talk about high stakes!
- Bullet chess: French Defense Exchange Variation is a small but shining jewel with an 85% success rate.
- Daily games: Kings Indian Defense Orthodox Variation remains an undefeated muse at a flawless 100% win rate.
One might guess Zacarias enjoys the tension of a ticking clock — after all, 1122 wins on timeout victories highlight some nerve-wracking finishes.
Memorable Recent Battles
Despite dabbling and triumphing in many battles, a recent game on Feb 28, 2025 revealed Zacachess’s blend of tactical precision and patience. In a Philidor Defense Hanham Lion Variation slugfest, Zacarias outmaneuvered Priemgetal1998, winning on time after a complex, 60-move endgame. It’s not just winning, it’s winning with style and stamina!
In short…
With a chess career marked by grit, tactical wizardry, and a sense of humor (who else racks up nearly as many wins on time pressure as from checkmate?), Zacarias M Ruben D is a dazzling example that chess mastery is more art than science. Whether you face them over the board or online, expect a battle packed with cunning, drama, and perhaps a few surprises.
