Re: Test Position
This is tough test position, Neither Bright nor Glaurung on Q6600 found it in few minutes.
This could get qualified as NOLOT test position.

Re: Test Position
Is there an engine that plays the Knight sac? Ancalagon only opts for 11... Bd6, eval goes to +2.6 so Nxf2 would have to go higher than that.

Re: Test Position
Finally after trying almost all the tactical engines Rybka finds it!
Chesstiger 2007.1 gambit sucide settings had a long think about Nxf2 but after 10mins still didnt pick it. I tried antihuman settings as well but still didnt tip it.
Well Rybka Winfinder 2.2 32bit SP that is The king of tactical suite positions finds it again!

Re: Test Position
Very good Dom! Thanks for trying this. Ancalagon eventually finds it too but three plies (adding two to Winfinder depths) deeper and lots of minutes later, although not on a dual core E4400 of course. Not accepting the piece does not help White.DomLeste wrote:Finally after trying almost all the tactical engines Rybka finds it!

New version
Build 48 with some changes in the 'Swindle Factor' at first seems to do worse but then it finds Nf1 as a reply to Bd6 with which I was pleased and I let it run a little longer. Et voila, Build 48 achieves a better solution time 
This could be either a slightly better version or more likely in the case of Ancalagon, the result of noise 
; with very speculative eval terms, and applying a sometimes even more speculative search, 'noisy' output in general is a problem, not only in testing your program changes of course.
