thanks for this collection.
Seems Number #3 position of Nolot test suite reappeared.

[d]r2qk2r/ppp1b1pp/2n1p3/3pP1n1/3P2b1/2PB1NN1/PP4PP/R1BQK2R w KQkq - bm Nxg5; id "Position 3";

Just around 15 seconds for the latest SF dev version. But around 1 min on my old 2-cores.
I told my wife that a husband is like a fine wine; he gets better with age. The next day, she locked me in the cellar.

Thank you for your efforts in collecting these things.
I really like it.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Thanks for this compilation and also for the SF analysis.
Seems the fifth position with bm Ng5xf7 is taken from Lc0 or other MCTS NN engine.
Because my SF analysis after forcing Nxf7 just shows 0.00 typical Lc0 and A0 move showing 0.00 but wins in endgame.

5) Ng5xf7 Ng5-e6 Ng5-e6 Ng5-e6
