What engines can actually find mate under 36 moves

Post by Chessqueen »

Not under analyses mode, but actually playing either by itself or another engine with this initial position :?:
Note: Next I will try Stockfish, followed by Berserk 10, you can use whatever engines you like.
Note: I believe that Stockfish will play and solve it the fastest without using Analyze mode, just simply playing against another top engine. Remember this contest is without using endgame tablebases at all :roll:

I set the contempt = 0 and Dragon performed better than before but it did not find the fastest mate, remember non of the engines can use tablebases for this contest :roll:

Re: What engines can actually find mate under 36 moves

Post by Chessqueen »

Next Igel 3.30 to see which engine can find mate the fastest, Not under analysis mode and NOT using any endgame tablebases, just pure calculation.

Re: What engines can actually find mate under 36 moves

Post by Chessqueen »

Rubichess has performed the worse so far giving Mate in 38 moves, without the use of tablebases. I will compare it to Blunder chess engine to see if can mate faster than Ribichess. There are a lot of top chess engines that without using tablebases will have a rating at least 50 points less then what their CCRL standing is :roll:

Re: Even Movei can mate faster than Blunder

Post by Chessqueen »

Blunder by pure luck found the correct corner to mate, but it did not have the programming codes to push the Black king to the corner where the Black Bishop can mate. Uri, since you have Movei and I do NOT I believe that Movei can find the Mate much faster than Blunder, can you test this position without using any tablebases? ==>

Spike 1.4 is a low rated engine, but with a punch this position is tricky for engine without using any tablebases? ==>

Rubichess has performed the worse so far giving Mate in 38 moves, without the use of tablebases. Next I will pit Colossus2022a Vs Rubichess. There are a lot of top chess engines that without using tablebases will have a rating at least 50 points less then what their CCRL standing is :roll:
