Nxa4 (since there's a nice refutation to Qa7).

Re: Test Position
Even though this was a move played by Stockfish it can still be a difficult position for it because 20. Bb5 also gets a good score, but not so high as 20. Nxa4. So it can take many minutes to find this but maybe the regular Stockfish 1.6.2 is a lot faster. This is 1.63s(dc) again with extra singular extensions:

But, this was with eight threads! Stockfish 1.6.2 completely out-calculating Stockfish 1.6.3s(dc) here though and also Stockfish 1.6.2
What is the time with 1 thread I wonder?

But, this was with eight threads! Stockfish 1.6.2 completely out-calculating Stockfish 1.6.3s(dc) here though and also Stockfish 1.6.2
What is the time with 1 thread I wonder? Regards, Eelco

Re: Test Position
The new PocketFritz4 with Hiarcs 13 engine finds 20.Nxa4 after 25:46 and at Depth=16 on a relatively slow PPC.On a fast HTC HD2 mobile it should find in approx 7 min.

Re: Test Position
Thanks for that, PF4 also has the Crafty 23.0 version which I plan to test this position on.From your Mnps data I guess that your 8 core is running about 465 times faster than the PPC.bob wrote:Here's crafty on my normal 8-core box:Cubeman wrote:The new PocketFritz4 with Hiarcs 13 engine finds 20.Nxa4 after 25:46 and at Depth=16 on a relatively slow PPC.On a fast HTC HD2 mobile it should find in approx 7 min.I killed it at that point.Code: Select all

What version of Crafty does your box run?
And how much stronger than 23.0 version?
Also can you test the move 20.Bb5 as my analysis says that it is no-where near as good as 20.Nxa4, and is only good for a miniscule advantage.

Re: Test Position
Just finished testing Crafty 23.0 on the same PPC.It basically found 20.Nxa4 after 36:46 and D=15 eval +0.55 and was reporting 49kNs at time of find.
