Movei finds the second position at depth 1 for positional reasons.
In the First position it seems to me that the target is not only to avoid Nc4 but to find the right move Qf6 because Qf8 Nxg6 is good for white.

Looks like DrunkenMaster would lose this game. Takes over 2 minutes on a 1.6Ghz PentiumM to avoid Nc4 and then it still doesn't find the best moves. I think one of the next things I'm going to work on is adding checks to my Q-search.

For the next position, it likes the sac in under a second but doesn't see it as probably winning until 22 seconds.

Division 1 engines perform miracles.
I don't know how long BigLion 2.23i takes for both positions because
I really don't know how to analyze with BigLion.
Analysis mode is yet untested in UCI mode and not implemented in WB mode
because I don't understand the WB protocol tov.

Djinn is ripe for Premier League. Any attempts to "improve" it can end
in an unnecessary weakening.

BigLion - Deuterium
How long does your engine take to avoid the suicidal Nc4 and settle for
Qf8/Qf6 ?

Looks like DrunkenMaster would lose this game. Takes over 2 minutes on a 1.6Ghz PentiumM to avoid Nc4 and then it still doesn't find the best moves. I think one of the next things I'm going to work on is adding checks to my Q-search.

I didn´t test these position yet (yesterday we built Spike 0.6 release - currently in test), but this position don´t seem to be complicated to find.
Have you got:
1. Code that evaluate the "attack" to the enemy king?
2. Code that evaluate the pawn-shield?
Both should give enough eval for the missing pawn.
IMHO first add the above eval - code before trying check-extensions in q-Search. Maybe you result in fixing an eval hole by adding search. I never got good results with check-extensions in q-search for IceSpell.
On the other hand: Fruit is very strong and it has check-extensions!
Thus i´ll be interessted in your experience.

Movei finds the second position at depth 1 for positional reasons.

Division 1 engines perform miracles.
I don't know how long BigLion 2.23i takes for both positions because
I really don't know how to analyze with BigLion.
Analysis mode is yet untested in UCI mode and not implemented in WB mode
because I don't understand the WB protocol tov.
/Matthias.

Hi Matthias
For analysis neurosis also doesn't have an analysismode (still can't read
winboardcommands while thinking..) but you can simply set your program to
think for a certain time? So in the winboardversion of neurosis from the
beginning I made that I can set 1 move in x time. For instance 1 move in 10
minutes, then it'll think for 10 minutes (minus 5 seconds to avoid going
through the flag.) And that works ok for me. (sort of.. till I ever deside
to solve the reading-commands-while-thinking)
In the first position neurosis (in normal materialistic mode) needs depth 8
to see Nc4 is bad tactically. But unfortunatly on that depth 8 it finally
settles for Kg7 and does not find out this is bad too till depth 10, and then
it takes a huge amount of time to resolve the drop in score, and finally
settles for Qf8. So in conclusion neurosis would lose this game too.

Hi Stan,
I have a GUI version of BigLion in which I paste and analyze FENs.
Just too lazy to compile version 2.23i .
Best,
Matthias.

Looks like DrunkenMaster would lose this game. Takes over 2 minutes on a 1.6Ghz PentiumM to avoid Nc4 and then it still doesn't find the best moves. I think one of the next things I'm going to work on is adding checks to my Q-search.

I didn´t test these position yet (yesterday we built Spike 0.6 release - currently in test), but this position don´t seem to be complicated to find.
Have you got:
1. Code that evaluate the "attack" to the enemy king?
2. Code that evaluate the pawn-shield?
Both should give enough eval for the missing pawn.
IMHO first add the above eval - code before trying check-extensions in q-Search. Maybe you result in fixing an eval hole by adding search. I never got good results with check-extensions in q-search for IceSpell.
On the other hand: Fruit is very strong and it has check-extensions!
Thus i´ll be interessted in your experience.
Greetings Volker

Yes I have code that evaluates pawn shield and king safety. Like everything else in my engine I'm sure it could be improved but I think the king safety is not too bad. As can be seen in the second position, it likes the sac very early for positional reasons. Even early in the first position after Nc4, it sees the next move for white as Nxg6. But to see the tactical shot as winning probably takes more. Or maybe I just need the right extension in my normal search function.
I haven't experimented with checks in Qsearch yet but it is something I want to try. In test matches with other engines, I can often guess which engines have this just by watching the games. Tord has written several messages about this topic in the CCC forum. It seems to help in king attacks/defense, just don't want to make the search tree too big.
Thanks for your reply.

BigLion - Deuterium
How long does your engine take to avoid the suicidal Nc4 and settle for
Qf8/Qf6 ?
1r1q2k1/pp3p2/2p3p1/n2p4/3P1NQp/2P5/P1P2PPP/4R1K1 b - - bm Qf8, Qf6
 abcdefgh  8       8  7       7  6        6  5        5  4      4  3         3  2     2  1        1  abcdefgh ChessDiag V1.01 (12-OCT-2002)1r1q2k1/pp3p2/2p3p1/n2p4/3P1NQp/2P5/P1P2PPP/4R1K1 b - - 0 1

... and

How long does your engine take to sac home the victory with Nxg6 ?
1r1q2k1/pp3p2/2p3p1/3p4/2nP1NQp/2P5/P1P2PPP/4R1K1 w - - bm Nxg6

/Matthias.

Movei finds the second position at depth 1 for positional reasons.
In the First position it seems to me that the target is not only to avoid Nc4 but to find the right move Qf6 because Qf8 Nxg6 is good for white.
Uri

Yes, but Qf8 turns out to be more interesting than at first glance. Looks like it would take a long think to avoid it for the right reasons.
