Ogün - The Chess Adventurer Known as ThatDay1

Once upon a chessboard, in the mystical realms of Rapid, Blitz, and Bullet, emerges Ogün, or as the internet knows him, ThatDay1. A player whose journey through openings and endgames resembles a rollercoaster ride — thrilling, sometimes bumpy, but always entertaining.

Rating Rollercoaster & Playing Highlights

Ogün reached his peak Rapid rating of 962 back in February 2020, showing early promise and a knack for kingside attacks. His Blitz peak was even sharper with a rating of 1020, also achieved in early 2020, revealing flashes of lightning-fast thinking and daring moves. Bullet speed chess? A respectable peak of 638 proving he’s not just a one-trick pony.

More recently, in the year 2025, Ogün is still on the battlefield, holding a Rapid rating of around 398 and showing steady improvement and determination.

Favorite Openings (and Occasional Gambits)

• King’s Pawn Opening: Ogün has played this classic in Rapid chess 252 times, boasting nearly a 49% win rate. Occasionally, he ventures into the Kings Knight Variation but knows it’s a brutal battleground.
• Bishop’s Opening & Alekhine’s Defense: These openings suit his style well, with win rates hovering around 50-55%, showing his taste for both classical and unorthodox lines.
• Englund Gambit Enthusiast: A bit of a wild card move, it earns him a solid 50% win rate, proving he’s not afraid to dance on the wild side of the chessboard.

Playing Style & Psychological Insights

Ogün isn't the type to quit easily. With a comeback rate above 52%, he's the classic underdog who fights tooth and nail after losing a piece, even if his win rate after losing one drops to about 35%. (But hey, at least he tries before resigning early – his early resignation rate is only about 15%.)

His games average around 38 moves per win and 42 moves per loss, suggesting he enjoys a good long fight and doesn’t rush into conclusions. Also, his White pieces bring him better fortune with a 50.5% win rate compared to 43.6% when playing Black.

As for timing, 7 AM seems to be his secret weapon — his best time of day to play, almost like he’s fueled by morning coffee and fresh tactical ideas.

Memorable Battles

One of Ogün’s recent triumphs was a dazzling game against JesusSaM99 on June 1, 2025, where he executed a mighty checkmate on move 64 after a Sicilian Defense battle that would make even grandmasters raise an eyebrow. You can watch that victorious game here, illustrating his sharp tactics and patience.

But it’s not always smooth sailing. Losses come with their own tales, such as a tough match against XXIXVIMM29 on May 31, 2025, featuring dramatic sacrifices and complex middle game skirmishes.

Stats by the Numbers

• Total Rapid record: 486 wins, 494 losses, and 52 draws – a true nail-biter series.
• Blitz record: 4 wins and 8 losses, bullet standing at no wins, 1 loss, hinting that lightning fast games could be improved with a bit more practice.
• Ogün’s longest winning and losing streaks both clocked in at 9 games. An emotional rollercoaster for sure!

Final Thoughts

In summary, Ogün aka ThatDay1 exemplifies the true spirit of a passionate chess player: unafraid of unorthodox choices, battling consistently, and always ready to outwit the opponent one tactical shot at a time. Whether it's the steady grind of Rapid or the chaotic blitz arena, he approaches every game with grit, determination, and just enough unpredictability to keep opponents on their toes.

So next time you face ThatDay1, beware: behind those ratings and numbers is a fearless warrior who will either checkmate you with style or give you a run for your money!
