Have you ever beat a GM on lichess?

Nope, only NMs. But I do only play 3+0 and over.

@EwoudUtrecht Yes of course that counts! They made a big mistake underestimating you :D

ultrabullet is just about flagging

I have only ever beaten one GM--Stripunsky. In a 15-min game on ICC (long long ago).

Yes. As well as otb.

wow @Sarg0n congrats but in what time control

OTB is the real deal! Nice Sargon

For example, this was played at the official German Blitz ch 2008, otb. 32 players, 31 tough rounds. I scored 7.5 points.
