Geir Sune Tallaksen Østmoe (aka Girkassa)

Geir Sune Tallaksen Østmoe, fondly known in the chess world as Girkassa, is a formidable International Master who dances on 64 squares with both grace and cunning. Earning the International Master title from FIDE is no small feat, and Girkassa has certainly lived up to the hype by consistently delivering riveting performances in rapid and blitz games.

With a rapid rating peaking proudly near 2500 and a blitz rating soaring past 2580, Girkassa is a speed demon who thrives under pressure — particularly when the clock is ticking and the audience is holding its breath. Their blitz record boasts an impressive 20 wins out of 29 games using a secret weapon opening (which remains exactly that: top secret).

One notable quirk is a winning streak so glorious it lasted an astounding 7 games, proving that when the pieces align, Girkassa is near unbeatable. The comeback rate following a lost piece is a staggering 100%, highlighting an almost supernatural ability to turn the tide even when the odds seem bleak. If you manage to snag one of their pieces, prepare yourself — this player bites back fiercely!

Psychologically, Girkassa maintains a surprisingly low tilt factor of 2, meaning they don’t throw tantrums over a lost queen or a misplaced pawn. However, casual games are a different story, with a noticeable performance drop compared to rated matches — and who could blame them? Casual play just doesn’t have the same thrill when there's no title on the line!

With a preference for long, strategic endgames (clocking an average of 69 moves per win!), Girkassa takes their time crafting victories, patiently outmaneuvering opponents before delivering the final checkmate. Interestingly, they’re slightly more dangerous playing Black, with a 64.52% win rate, proving they can thrive even when playing second fiddle.

Off the board, you might catch them sharpening tactics at dawn (100% win rate at 6 and 7 AM - early bird advantage!) or dazzling opponents late at night as their win rate spikes around 10 PM. Saturday, however, is apparently not their day — no wins recorded.

If you see Girkassa online with their notorious “Top Secret” opening in play, brace yourself for a tactical storm, because Geir Sune Tallaksen Østmoe doesn’t just play chess — they perform a subtle symphony of strategy, wit, and resilience that can embarrass even the most seasoned grandmasters. Just ask any of the 100% defeated opponents on their list!

Fun fact: Despite their fierce competitiveness, Girkassa boasts a perfect zero on early resignation — giving every game a full-hearted fight to the bitter end.
