Plays GoK with white ? And is checked by Bonzai. So Bonzai wins ? Or ??

Is this a right decision? Normally this stays on 0.5-0.5

Well it's knockout mode, and I tried a replay. But those two engines seem to play identical games against each other; also no chance to switch sides as the projects don't support that.

Hi, yes I wanted to run LowDoor on Depth 5 originally, but it ran into very long think times and browser timeout warnings back then. However I tried again now, and although it took a while, I was able to finish a game. GoK (Medium, white) won it in 19 moves: https://lichess.org/d7eAWVLq

Yes, but you have to consider time too. If the engine uses minimax, the more moves ahead it looks the stronger it will probably be. But doing this will take a lot longer time for the engine to think. So it will be unfair if an engine is thinking a lot longer than an other engine.
