Mariia Manko (aka Mary_cool)

Woman International Master

Meet Mariia Manko, a chess wizard who doesn’t just play the game—she conquers it. Awarded the prestigious Woman International Master title by FIDE, Mariia blends sharp tactical awareness with a gameplay style that’s as resilient as it is dynamic. When she’s not outwitting opponents across boards, she’s probably plotting her next winning streak of 17 games or fine-tuning her endgame mastery, having a remarkable 79% endgame frequency.

Starting her blitz journey with a modest rating of 924 in 2019, Mariia skyrocketed to an impressive peak rating of 2152 by March 2024. She dominates in rapid and blitz formats alike, boasting win rates near 60% in blitz and almost 74% in rapid games. Her signature opening remains top secret—literally—because with 230 blitz games under her belt, opponents are still guessing which trap she’ll spring next.

Mariia's psychological resilience is legendary; she boasts a comeback rate of over 83%, meaning losing a piece doesn’t faze her—it just fuels her fire. Her average moves per win hover around 71, proving she’s unafraid of long strategic battles and isn’t quick to resign, except maybe 7% of the time when the position truly screams checkmate.

Known online as Mary_cool, she’s a force to reckon with at any hour but has a clear favorite: 9 PM sharp, when her win rate spikes to nearly 86%. Fun fact—her games typically end with resignation (either hers or her opponents'), showing that in her games, it’s checkmate or concede.

Recent Highlights

  • Latest victory: A powerful win in the Queen’s Gambit Declined with a razor-sharp attacking finale!
  • Longest Winning Streak: 17 in a row. Some say she uses secret chess potions; we just know she’s cool under pressure.
  • Favored Opponents: Mariia has faced "aquaregia10" the most, taking victories in all 7 encounters – talk about dominance!

Whether blitzing with ferocity, rapid-fire strategizing, or casually schooling opponents online, Mariia remains a captivating mix of precision, grit, and a subtle sense of humor. Opponents beware: behind that calm username Mary_cool lies a tactical storm with the WIM title as her badge of honor.
