My hard test suite 2008

[Vinvin]

Hi Vincent,

Thank you for the suite, they are always time consuming to gather and verify.
For the record, game 49 (King's Attack) is Marcozy-Tartakower (1922): http://www.chessgames.com/perl/chessgame?gid=1003826

Infos added, Thanks !

Thanks for sharing this.
I guess pos6 (Bh3) won't be played by any engine. I think it is winnig, but was it the best move? It was Shirov playing this, right?

[Vinvin]

But what about instead of 4...Kc5??, black to play: 4...Ka4!!
8/5p2/1ppp4/8/k4P2/7P/8/5K2 w - - 0 5

I have on this:

[Event "?"]
[Site "?"]
[Date "2007.07.14"]
[Round "?"]
[White "?"]
[Black "?"]
[Result "*"]
[Annotator "George"]
[SetUp "1"]
[FEN "8/5p2/1ppp4/1k6/5P2/7P/8/5K2 b - - 0 1"]
[PlyCount "17"]

1... Ka4 $3 (1... Ka5 $2 {draw} 2. h4 b5 3. h5 b4 4. Ke2 Ka4 5. h6 b3 6. Kd2
Ka3 7. h7 b2 8. h8=Q b1=Q 9. Qa8+ Kb2 10. Qxc6 Qg6 11. Qb5+) (1... Kc5 $4 {lose
} 2. h4 Kd5 3. h5 Ke6 4. h6 Kf6 5. f5 b5 6. Ke2 d5 7. Kd3 b4 8. Kc2 d4 9. Kc1
c5 10. Kc2 c4 11. Kc1 d3 12. Kd2 b3 13. Kc3) 2. h4 b5 3. h5 b4 4. h6 b3 5. h7
b2 6. h8=Q b1=Q+ 7. Kf2 Qc2+ 8. Kg3 Kb5 9. Qb8+ Kc4 *

It seems correct (and very annoying ), Black seems better after Ka4!
I didn'd find any reference to this position, may be someone could help ?

I don't get this solved after 45 minutes on a quad : b4 is the 3rd choice (doesn't mean this isn't best, though):

Is it possible for someone to post this suite in .epd format?

Thanks

I remember some top engines find it

Is it possible for someone to post this suite in .epd format?

Thanks
Dave

There are 1182 records in it (assuming that the pvs are also optimal).

What i would like to have is just the .epd positions with the "bm" (best move). I really don't want to do this manually. Is there a utility that will extract these positions and convert to a .epd test suite?

Dave
