Marc Kirszenberg: The 1.d4 Devotee
Marc Kirszenberg, better known on chess servers as campomania3, is a FIDE Candidate Master with an almost terrifying appetite for the royal game. Across close to 15,000 online games, he has become a familiar name in blitz queues around the clock. Despite the blitz-heavy workload, his preferred time control appears to be rapid:in recorded rapid games, he remains undefeated,with nine wins and two draws, anda peak rating of 2256 (2022-03-24) in early 2022.
Loyal to the Queen's Pawn
As White, Marc rarely flirts with flank openings. His game history is a love letter to 1.d4, and his opponents know it. He has built his reputation around punishing the Nimzo-Indian Defense and King's Indian Defense, while feasting on those who choose the Slav Defense, where his white win rate exceeds 63%. He might not be the most unpredictable player with White, but he is certainly one of the most persistent.
As Black, he trusts the classics. The Caro-Kann Defense appears more than 1,200 times in his history, giving him a sturdy base against 1.e4, while the Scandinavian Defense provides his inner swashbuckler an outlet, with a win rate around54%. It is a repertoire built for longevity, not flashy one-liners.
The Comeback Specialist
Marc's games tend to last because his opponents rarely find a way to put him away. His endgame frequency approaches80%, and the average decisive game runs past70 moves, meaning he is fully comfortable suffering through long, technical grinds. He responds to adversity well:he still wins nearly half of his games even after losing material, and his comeback rate approaches83%. Opponents have been known to relax too early, only to watch Marc quietly rebuild a fortress andhen steamroll the ending.
He is especially dangerous in the early morning, with his best win rate arriving around07:00, perhaps because he has already had his coffee and his rivals have not. His white win rate sits near55%, while his black win rate remains a solid48%;both numbers speak to a player who never stops fighting, regardless of the color of his pieces.
Rivals Who Know Him Too Well
An online career as long as Marc's creates familiar faces. His most frequent opponent, rdors, has faced him nearly50 times in a rivalry that has gone back and forth with astonishing intensity. The names Najd Mbarek and Tomas Celedinas also appear throughout his history as regular dance partners. These are players who have learned to expect the unexpected:that Marc will take losses, request rematches,and keep coming until the position yields its secrets.
