"Deep Slop"

by IM Mark Ginsburg

[This appeared, I think, in the April 1992 _Chess Chow_]

Famous IBM research project/chess program Deep Thought is a
welcome addition to the Internet Chess Server scene.  Going by
the alias of "Scratchy", this version of DT (DT-2) is
terrorizing other humans and programs alike  (even though
Gnuchess seems to be moving quicker every day!).  

The current version of this program is not yet rated, but the
last incarnation was 2514 USCF.

The chief programmer, Feng-Hsiung Hsu, calls this version 
"obsolete".  Well, it's still strong.

DT-2 has quickly soared to number one status, most convincingly
in blitz.  Feeling honor-bound, so to speak, to uphold the
banner of humanity I had a go with it in the following hot,
sweaty May encounter:

Deep Thought 2 - IM Mark Ginsburg  15/15 game, ICS 1992

1. e4 g6 2. d4

To mystify me, DT spent 47 seconds on this move.

 2...Bg7 3. Nf3 d6 4. Be2 Bg4 5. o-o Nf6 6. h3 Bxf3 7. Bxf3 Nc6
8. c3 O-O 9. Be3 e5 10. d5 Ne7 11. c4 Nd7

Now I'm kind of happy.  This type of position offers black
kingside chances.  I was more worried about white keeping the
center fluid.

 12. Qb3 b6 13. Nc3 f5 14. Qd1 Nf6 15. b4 a5 16. a3 fxe4 17.
Bxe4 Nf5 18. Bxf5 gxf5 19. Bg5 Qe8 20. Bd2 Qf7

The queen could have gone to g6 in one go.

 21. Qf3 Qg6 22. Nb5 Ne4 23. Be1 Rf7 24. Rc1 ab4 25. ab4 Bh6 26.
Rb1 Rg7 27. h4

This looks like a concession but I'm getting a little short of
time now.

 27...Bd2(!) 

To get a very useful defensive piece off the board.

28. Rb2 Bxe1 29. Rxe1 Rf8

At the time I wasn't sure if I should abandon the a-file but now
it looks like a good choice.

 30. Kh1 Qh6 31. g3 Ng5 32. Qg2 f4

Met starke aanvaal, ja?

 33. Rb3 fxg3 34. fxg3 Rgf7 35. Rb2 Kh8!

A necessary prophylaxis before proceeding.

 36. Qd2 Rf4! 37. Qe3 Nf3 38. Ree2 Rxh4!+

A crushing blow to culminate the attack.

 39. gxh4 Qh4+?? 

DT later informed me, by way of Murray Cambell, that 39...Rg8!
would do the trick.  The human is starting to go downhill now!

40. Rh2 Nxh2 41. Rxh2 Qxc4 42. Rf2!

Nice one!  White is in no danger now.

42... Qxd5+ 43. Kh2 Rg8!

43...Rxf2 44. Qxf2 Kg8 is not going to be too pleasant for
black, although he might hold.

 44. Qh6 Qxb5??

Oh, the humanity, the humanity.  I thought it had to go for a
perpetual now!  A few seconds more and I would play the obvious
44...e4! and black cannot lose.

I suspect that DT would force an immediate perpetual check with
45. Qd8+ or 45. Qf8+ after 44...e4!.   In fact, if white
blunders with 45. Nxc7? (much more plausible for a human than
DT, of course) then 45...Qe5+ forces mate in all variations (!):
a.  46. Qf4 Qh5+, b. 46. Rf4 Qb2+, c. 46. Kh3 Qc3+, d. 46. Kh1
Qa1+. 

45. Qf6+ Rg7 46. Rg2  

Ugh!  46...Qd7 47. Qf8+.

1-0

DT-2 diverges from 7...exd5 8. a3 Bxc3 9. bxc3 b6 10. O-O Ba6
11. dxc5 bxc5 12. Bxa6 Nxa6 13. Qa4 Qb6 14. c4! which left white
somewhat better in a previous aries-DT game.

The machine wants to get active on the kingside.

Very aggressive play!

12. Bg5 (0:10) Qc7 (0:16) 13. N2g3!? (0:39)   

Maybe DT-2 will grab my d-pawn!  I've prepared a nippy
continuation...not sure how good it is...

      13...h6 (0:16)

Oh well, it wants to play safe.  I guess it's right; let's see,
any way to keep going?  Yes...

14. Qh5 (0:49)

I'm trying to have fun and mate the thing.

14...hxg5 (0:15) 15. Nxg5 (0:05) Nf6 (0:10)

Fun time's over.  It's just a draw.

An interesting line and not clearly worse than the more usual
7...g5.

8. Bg3 (0:06)

A suggestion of Taimonov's (in his German-language opening
series) to keep some pieces on.

Another mysterious move.

18. e5! (0:10) dxe5 (0:14)

White's clearly on top now; the doubled c-pawns help control the
center.
