Alejandro Adrián Riline Orso: The Durable Dynamo
Alejandro Adrián Riline Orso, better known to his online rivals as alejanchess73, is a FIDE Candidate Master who treats the chessboard like a lifelong friend. His data shows a player of astonishing volume, fierce resilience, and a clear love for Rapid chess, though his Blitz numbers are equally fearsome. He has faced thousands of opponents, yet remains instantly recognizable by his signature openings and his refusal to give up.
Marathon Man
Alejandro's online career is a mountain of games. He has logged more than 10,000 Blitz wins and 10,000 Blitz losses, a ratio that only a true glutton for punishment could sustain with a smile. His longest winning streak is a jaw-dropping 146 games, while his longest losing streak of 49 games proves he does not hide from adversity. In fact, his comeback rate is 85.2 percent, so crossing the finish line first against him is never safe.
He prefers to play Rapid, the time control that lets him blend calculation with intuition. His Rapid peak reached 2308, but his Blitz exploits are just as impressive, climbing to a peak of 2620 (2026-02-28). His trajectory is visible in the chart below, a wavy mountain range of persistence.
Signature Repertoire
Alejandro has a playful relationship with opening theory. He is particularly at home in the Alekhine Defense, where he has played hundreds of Blitz battles, and he also loves the Sicilian Defense in all its flavours. In Daily chess his opening results are even more colorful, with an 86.44 percent win rate in the Dutch Defense and a remarkable 83.48 percent in the Scotch Game.
His rapid play has been nearly perfect in the Sicilian Defense, winning all five recorded Rapid games in that opening. He also shines in the King's Indian Defense with the Sämisch Variation, where his Panno Formation results are a perfect 100 percent. When he needs a surprise, he turns to offbeat systems, which keeps his opponents guessing from move one.
The chart below shows how his opening choices have performed across his most played lines.
Rivalries and Battles
No biography is complete without a worthy rival. Alejandro has faced goran_galiot 83 times in online play, a rivalry so tight that his record stands at 39 wins, 38 losses and 6 draws. Every game between them is a knife edge. Their battles have shaped his defensive instincts and taught him how to grind out results against familiar faces.
He also enjoys rich rivalries with psyk6, jbgd and andro2, each appearing dozens of times in his match history. His ability to keep coming back for more against the same players explains his remarkable sense of calm under pressure.
Inside the Numbers
Alejandro is not just a grindder. His average winning game lasts 78 moves, which means he enjoys turning small advantages into long, slow squeezes. His average first capture comes on move 7.5, so he is not afraid to enter contact early. With an endgame frequency of 78.79 percent, he regularly outlasts opponents in the final phase of the game.
- White win rate: 52.17 percent.
- Black win rate: 46.82 percent.
- Early resignation rate: just 2.82 percent.
- Win rate after losing a piece: 47.72 percent.
- Best time of day to play: 09:00.
He is slightly more dangerous with the white pieces, but his black repertoire is far from passive. His willingness to fight on after losing material is one of his most dangerous traits, and it explains why so many opponents fail to convert winning positions against him.
The Morning Philosopher
Psychological data suggests Alejandro is sharpest early in the day. His best time to play is 09:00, when his win rate jumps to 67.67 percent. He also performs well during late night hours, showing a flexible chess brain. His tilt factor is 49, meaning he mostly keeps his emotions in check even after painful losses.
His peak Rapid rating of 2308 (2026-03-14) arrived after years of steady work, proving that online chess rewards patience and adaptability. He may prefer Rapid now, but he has demonstrated elite-level skills across every time control, from Bullet to Daily chess.
