Hello, guys! Since we don't have 1/8+0 yet, I decided to ask Lichess for berserk only option for ultrabullet tournaments. Please support this feature request if you like the idea of 1/8+0, so we could be able to enjoy 1/8 in tournaments at least without a major obstacle of some people not berserking:
