I haven't had CPU time to do a full scan on all these tests but I tried the first 11 in multi-variation mode at 45 minutes/move over the past couple of days. I am using the EPD version I posted here:

http://www.arasanchess.org/lj-beta3.epd

I think most of these are just too hard for Arasan.

Pos 1- not solved: Qc3, Ra7, Re6 selected (all with 0 score)
Pos 2 - solved & valid - Rxa3 score +9.42; 2nd move is Qd6 score +3.11
Pos 3 - not solved; best mvoe is Be5, score +0.48
Pos 4 - solved & valid; Nxf7 score +1.35; 2nd move Nf3 score +0.52
Pos 5 - others have reported Qg3 & Qg4 as alternate solutions, but
Arasan likes Qg3 best with score +1.39. Here is the full result with pvs:

result: Qg3 2500 seconds. score:+1.39 3030500401 nodes. ++ correct
Qg3 Qd4 Rf4 Qc3 Qh4+ Ke8 Rf7 Bf8 Qh5 Kd8 Rxf8+ Rxf8 Rxf8+ Kc7 Rf7+ Kb8 h4 Qxc2 Q
xh6 Qb1+ Kh2 Qxb4 Qf4 Qc5 Qf2 Qe5+ Kh3 Bb7
result(2): Qg4 2500 seconds. score:+0.11 3110026710 nodes.

Pos 6 - I skipped this for some reason - no result yet
Pos 7: not solved; best moves Qf5, Qf7, Be7 (all close in score)
Pos 8: not solved; Arasan likes Bg4 best
Pos 9: not solved: best move Nb5
Pos 10: not solved; best move fxe6
Pos 11: Arasan found Nf5 first but Nxh5 gets about the same score:

result: Nf5 2500 seconds. score:+1.82 2979254796 nodes. ++ correct
Nf5 gxf5 Rxf5 Qe8 e5 dxe5 Bh6 Ra6 Bxg7 Kxg7 d6 Rxd6 Qxd6 f6 Ra1 Bc8 Ra7 h4 Bd1 Kg8 Rh5

Hi Jon :) ,

you are right. Some are really hard to solve and even Rybka 3 human only finds them when going deeper into the lines, like for example position 13.

So far I investigated positions 1 to 13 with Rykba 2.3.2a, Rybka 3 human and Zappa Mexico II with long time controls and going sometimes deeper into the variations.

All seem to be valid without alterantives being equally (or almost equally) strong with a few expections. Position 5 was already mentioned by Uri and I confirm.

Then we have position 3. Here 1...Rg1 seems to be an almost equally good alternative according to Zappa and Rybka when analyzing further.

Code: Select all

1. Be5 $1 (1. Rg1 Bf6 2. Rxc5 Rxc5 3. dxc5 Qb4 4. Bd6 Qxh4+ 5. Kg2
{0.80}) 1... f6 2. Rg1 Kf7 3. Rxg6 (3. Rh8 fxe5 4. h5 Bf6 5. hxg6+ Ke7 6. g7
cxd4 7. g8=Q Rxc2 8. Bxc2 Bxh8 9. Qxh8 Nd7) 3... cxd4 4. Rxf6+ Bxf6 5. Rh7+ Ke8
6. Bxf6 Qb4 7. Qe4 {0.85} 1-0
Position 4 is okay, but not necessarily leading to a big advantage for White.

Position 7 is okay. There are no alternatives giving advantage to Black, but not accepting the rook sacrifice with 1..Bg2 White can defend more tenaciously. A bit more than 0.70 advantage when proceeding.

Code: Select all

1... Rxh2 2. Kxh2 (2. Bg2 Rh6
$15 (2... Qh6) (2... Rh5)) 2... Qxf2+ 3. Kh1 Nf6 4. Re2 Qxg3 5. Qc3 (5. Nb1 $15
) (5. cxd5) (5. c5) 5... Qh4+ 6. Kg1 g3 7. Bg2 Qh2+ 8. Kf1 Ng4 9. Nxe4 dxe4 10.
d5 Be5 11. Qc2 exd5 12. Bxe5 Nxe5 13. Bxe4 Qh4 0-1
The other positions I think are very well apted for solving tests.

Investigations are continuing.

Nxh5 is clearly an alternate solution, as wrote in the PGN file.
So, Arasan is right ;)

Hi all :) ,

overall the test suit looks good. Some positions will remain to be solved on future hardware with future programs. For some it seems to be probable that the masters played those moves intuitively without calculating all till the end.

Positions 14 to 25 are all suited for testing with main solutions. An exception may be position 24 which is more about following a concrete plan in an endgame, but here there are no forced lines and the defender can act in many different ways. Impossible to check them all to see if Black is totally lost.

I never saw this alternative, very interresting !

Many thanks for your good work !
Do you use the pgn file to start the analyse (there's some usefull comments) ?
