let us solve chess with 7 piece odds - Chess Forums - Page 2

I have no doubt that theoretical value of chess is draw. but I wanted to do something different. I have adjusted the following position into droidfish 7: I wanna see how many moves can white mate with. It is now 20 plies depth and +43.77 if you have different engines can you do the same? May

I intended to do something. I was playing this line against chess.com CPU, when I reached the 12th move I opened analysis mode and it says mate in 5. faster than stockfish. I will upload the line

Could be..

I think this may be the reason we need Komodo or Houdini. at the time I reached the 13th move, I thought there must be better moves than 13 Qc5 and the other engine approved it. let us compare it:

I think this may well illutrate we need to use Komodo and Houdini as well. but now I am gonna try the line I discovered with another engine with Droidfish and I am gonna post it

Not necessarily. Stockfish 8 currently at ply 33 (...). As it will go deeper both the moves of 1-12 and above 12- will probably change.

I update the above results continuously.

seems to be so.

in the position I presented above, in 40 minutes only 33 plies depth is calculated.

Yeah, and I'm thinking that a minimum of depth 60 is needed to get the solution?

@tn85N, hardware specs?

45 hours with MultiPV = 20. Hardware is i7-980x (6 cores). Approx 7-8M nodes/sec.

Reported ply is not always equal to the deepest search depth reached, so probably reported 60 ply is not needed.

Now, mate in 22 moves (8p & K & B(Q)), check comment #17.

For 1. e4 and 1. d4 lines.
