I have asked ChatGPT on your behalf.
It seems like you're testing various chess engines (Igel 3.40, Koivisto 9.2, Stockfish, and Dragon 3.2) and evaluating their ability to find the best move in a particular position. It appears that only Stockfish and Dragon 3.2 have been able to find the move 1. Nf3, which results in a draw.

Please note that different chess engines may have different strengths and weaknesses, and the best move in a given position can also depend on various factors such as the time control and the engine's settings.
You’re welcome.
Fat Titz by Stockfish, the engine with the bodaciously big net. Remember: size matters. If you want to learn more about this engine just google for "Fat Titz".

You are correct, but I am giving 3600 Seconds per move which is 60 Minutes per move to find 1.Nf3, if Stockfish found it in 56 minutes it could be that the other weaker engines might need 90 Minutes to find 1. Nf3 which is the only move that can draw, but so far Stockfish and Dragon 3.2 are far ahead of the others engines as far as knowing when to Block the position like this.

I have asked ChatGPT on your behalf:
The optimal move 1.Nf3 in a chess game can lead to a draw, if both sides play optimally. The time given of 3600 seconds per move (60 minutes) is a relatively long time control, which gives the engines enough time to search deeply for the best move. Stockfish and Dragon 3.2 are considered strong engines and have demonstrated their ability to find the best move quickly. However, weaker engines may take longer to find the same move.

The question is how much longer, and it depend on the hardware, for instance if I use my laptop from 2013 it could take Stockfish 120 minutes to find 1.Nf3, but by 2025 the fastest P.C could probably solve it in 30 minutes per move or even faster. It actually took Dragon 3.2 at least 4200 seconds per move time control or 70 minutes per move to find 1.Nf3 :roll:

NOTE: I have a feeling that Slowchess will be the faster engine to find 1.Nf3

The optimal move 1.Nf3 in a chess game can lead to a draw, if both sides play optimally. The time given of 3600 seconds per move (60 minutes) is a relatively long time control, which gives the engines enough time to search deeply for the best move. Stockfish and Dragon 3.2 are considered strong engines and have demonstrated their ability to find the best move quickly. However, weaker engines may take longer to find the same move.
Besides Stockfish and Drqagon 3.2 there is no engine that can select 1.Nf3 in less than 4 Hours per move or = to 14,400 seconds per move, if I am wrong prove it to me :roll:

The latest development of Stockfish_23012506 is NOT as good as the previous, since it can NOT find 1.Nf3 in less than 60 minutes :roll:

Besides Stockfish there is no engine that can select 1.Nf3 in less than 1 Hours per move, if I am wrong prove it to me. Huntsman did NOT select the correct move 1.Nf3 after 60 minutes time control 3600 seconds per move = 60 minutes. You saw hoe Dragon 3.2 sacrificed its Knight on the 4th move 4...Nxe4! a Knight for 2 pawns and the Black Queen with an extra pawn against Rook plus Knight will surely win. That was a GREAT move to open up the position :roll:
