Knight in jeopardy test

Hello folks , Look at this position minute ,in depth and subtlety. rnb1kb1N/ppppq1pp/8/8/4n3/8/PPPP1PPP/RNBQKB1R There is a big claim here : that poor white knight shouldn’t capture black rook in h8 , so in the next move white will loose his queen (true), and WHITE KNIGHT in h8 can’t ESCAPE at all. ...

Re: Mortimer trap test bug in Stockfish 10

Thanks Dann for such a detailed explanation. Great! But something to consider : In the book “Comperhensive chess course “ authors present this as opening trap , and finally conclude that : There are 2 traps here. first mortimer trap , and then white player sets a COUNTER-TRAP by ignoring to save the...

Re: Mortimer trap test bug in Stockfish 10

Jp
You missed the point again .
It’s simple. I dont tell 6.Nc4 is so good or winning move. I’m telling it’s better choice than 6.Nxf7. and Stockfish can’t realize this .
Mike’s evaluation is after black’s move (6...Ng6). He didn’t test “best move” for sixth white move .

Re: Mortimer trap test bug in Stockfish 10

Jp, The eval can change , ok . But from what I observed after 10 moves (with best play for both sides according to Stockfish) (and by depths like 30 plies ) , Stockfish concludes that his initial choice (6.Nxf7) was wrong ! Now come back to the sixth move and Stockfish still chooses it ! Strange! So...

Re: Mortimer trap test bug in Stockfish 10

[/quote] This is not a bug, it's just an observation that Stockfish doesn't play perfect chess. [/quote] elapa, This is an awful fact! Why a high end software like stockfish 10 , on high end hardwares with 12 cores can’t choose a move correctly while in 1880 a normal chess player has found it?! 6.Nc...

Re: Mortimer trap test bug in Stockfish 10

Mike B ,
Is your mac pro a 12 cores or a 6 cores ?
Has you upgraded it ?
Does your system chooses 6.Nc4 ? Or 6. Nxf7 ? at how much plies ?
Thanks very much
