Known by the username jstopa4, Jacek has earned his stripes through countless battles on the digital battlefield, boasting a peak blitz rating soaring as high as 2845, a rapid peak of 2351, and a daily chess high of 2126.

Chess Style & Statistics
Jacek's style is a blend of patience and relentless pressure, with an impressive average of over 80 moves per game — proving that he doesn’t give up early and enjoys the long haul to victory. His endgame frequency clocks in at a staggering 82.56%, showing off his mastery in turning even the tiniest advantages into wins.
Despite the long battles, early resignations are rare — only 0.63% of his games — which means Jacek fights hard and rarely throws in the towel unless checkmate is imminent.
He's a comeback king too, enjoying an 85.61% rate of rallying after a setback, and manages a respectable ~45% win rate even after losing a piece. Clearly, dropping a pawn or knight is only a minor hiccup for this tactician.
Recent Form & Memorable Battles
Recent months have seen Jacek pushing his daily rating above 2000, and his blitz performances keep the adrenaline pumping with fierce competition — including an epic winning streak of 55 games that would intimidate even the calmest opponents. Though he’s experienced some ups and downs (including a challenging losing streak of 27 games), his fighting spirit shines through.
A notable recent victory came against JoopElderhorst, where Jacek's use of the Trompowsky Attack (Raptor Variation) led to a neat resignation win — a game where his patience and tactical sharpness left no room for error. On the flip side, even legends lose sometimes, as seen in a hard-fought loss against the same opponent in a close English Opening battle.
