SET League Final Round! Element goes 0/5…

OK, from these excellent tournament games (thanks Hasi!), I will proceed to invest in Element’s search depth going forward.

I was doing a GoK (difficult, TurboWarp (it was on 60FPS, does that change anything?)) v Stockfish 16 game with play vs computer on lichess, and GoK hung a bishop pretty early into the game.

GoK was white

1. e4 e5 2. Nc3 Nf6 3. f4 d5 4. fxe5 Nxe4 5. Nf3 Bc5 6. d4 Bb4 7. Bd2 c5 8. Bb5+ Nc6 9. O-O O-O 10. a3 Bxc3 11. Bxc3 Nxc3 12. bxc3 c4 13. Qd2?? Ne7 14. Ng5 a6 15. e6 Bxe6 16. Nxe6 fxe6 17. Rxf8+ Kxf8 18. Rf1+ Kg8 19. Qe3 Qd6 20. Ba4 b5 21. Qf3 bxa4 -+

GoK Classic Medium finds correct move at depth 11, in 11sec on my system. Seems search-depth-related, probably there are some delaying moves…

Yep it didn't take the bishop for 8 moves after the blunder.

Hello, I have not been feeling the best lately, but Element v1.6 is in the dev, but it does have a bug where it trades into losing pawn endgames (fixed in Stable v1.51). It also has an opening hole as white, but I figured I should mention the LMR update. The change is very noticeable on depth 7.
