Scratch Chess Engine - Game of Kings
I ran this on mobile, so the TT is probably not very good due to limited memory (after GoK played its move on Difficult, the tab refreshed automatically).Why doesn’t GoK see the checkmate here? White Dove sees it on ply 8.
It sees it at ply 1 in 4 seconds. Which level were you on? But maybe you ran into the ply 1 checkmate search timeout which I had reduced by your input ;-) However it should still find it later, latest at depth 8. Maybe TT reasons after limited ply 1 search.
I was halfway through reviewing your opening book; it has a lot of issues. Do you know where the opening book lines come from?

Dev version finds it at depth 1 in 1.7 seconds (and if I restrict check-sequence search a bit in length, it would be 0.2 seconds, but then the mate-in-15 of two weeks ago can't be found any more); when I disable that depth 1 special search, it is found at depth 9 in 6 seconds.
Please discuss opening book topics with Grijfland, he owns it.

The depth 1 time limit is a fraction of overall think time, that is the reason why you might need comp mode. On my system, no problem on Medium or Difficult

Checkmate in 5 now detected in 1.9 seconds at depth 1 for https://lichess.org/analysis/standard/1r1q2nQ/ppp3p1/4prk1/6N1/1n1P4/8/PP1N1PPP/R5K1_w_-_-_12_23
And this mate in 4 (with a lot of queen space and not continuous quiescence sequence) in 4.1 seconds at depth 6: https://lichess.org/analysis/standard/8/2N4p/8/8/4KP2/8/3k4/7Q_w_-_-_5_59
How are other engines dealing with those?

Crazy game by 10sec GoK (black) vs. White Dove (P2). I guess no side deserved to win, so draw is OK. Out of GoK's 4 biggest mistake, 2 won't happen on Medium (15sec), and 1 won't happen in competition mode. https://lichess.org/qzlUxLON#104
Rematch, GoK (white) winning at 96% vs. 92% accuracy: https://lichess.org/EcJRx0Ha#133
I had to reduce some of recent fancy 15-ply-plus check/evasion-sequence checkmate puzzle solving, to regain speed and search depth, and it immediately paid off. It might be a side effect of latest chances that GoK left the shortest checkmate path once.

Great report! Maybe I should add some more lines for WD that are not just for the French…

White Dove is doing very well against GoK lately. White Dove never finishes its winning endgames.
Just so you know, Element v1.4891 in the Dev has knight underpromotion, so you can use/test that if you like

Game #4 was a clear win for GoK (white): https://lichess.org/aEAekwv9#85
Series result:
GoK 3.0

I just reduced check extensions, think time / search depth is OK. Blunders' effect was far beyond search horizon, some games simply develop negatively…
Yes, I read about underpromotion, but I don't have special test scenarios, and it is not very likely to happen during normal games.

I have a few positions in the study, including this one from a GoK-WD game (WD blundered because it doesn’t have underpromotion). There was an M3 position that required a knight underpromotion, but I have lost the FEN.What happened here?

Absolutely, it was always planned, but it never happened.
Now just have to find some time for it.

GoK (Medium, white) vs. Element (6+8), GoK wins at 96% vs. 91% accuracy; https://lichess.org/3KkoTvH8#131I was not able to replicate a5 (Nd4) on Stable or Dev versions of Element. I should add the #OfMoves into the FEN, but the move is the same after manually changing it. This could be due to some sort of FEN inconsistency (they are common in Element).
