Since Hannibal doesn't use a multithreaded search, it seems quite likely that Hannibal's search is deterministic. This would explain the consistency of your five results, though not how the engine is finding Nxh7 so quickly.

[EDIT] Compare the output you posted to the output here:

http://talkchess.com/forum/viewtopic.ph ... 28&t=44020

Same score and same number of nodes, since the search is deterministic.

Good observation, thanks.
But 64-bit Hannibal seems slower than 32-bit contrary to the discussion in
other threads where they claim a bitboard engine will be faster in a
64-bit compile.

Hope Sam Hamilton or Edsel Apostol can enlighten us on why Hannibal
can find such a difficult sac in just seconds.

4 seconds for you vs 13 seconds for Lonnie Cook's 64bit Hannibal, for the same search. Different hardware and different size hash tables I suppose.

Yes, I'd like to know too.

Actually it only took 3 seconds on my machine. I just clipped the analysis at 13 seconds when I decided to capture it to post on the forum.

Hello:

I must say that Hannibal is very fast... but we can not forget Spark! I have Bright 0.4a and it found the correct move after 42 seconds in my slow computer (already a good job). So I have just downloaded Spark 1.0 and gave it a chance.

I have always heard excellent things about Spark regarding its sharpness, especially from Frank Quisinsky and his now finished project SWCR. Well, only 1.14 seconds are enough for Spark 1.0 to find Nxh7 in my PC, so I guess that 64-bit versions on better hardwares (quads or more) will find this great move in less than a second.

I also want that Allard Siemelink will enlighten us on why Spark is such a beast in this position. A new version of Spark will be greatly appreciated.

Regards from Spain.

It only took 3 seconds on my machine. I just happened to clip it at 13 seconds but it found Nxh7 way beforehand at 3 seconds.
