This was a nice game. I managed to get to be the one operating this one, so I took note of the Tasc's display for those who are interested:
[White "Tasc R30"]
[Black "Polgar 10 MHz"]
[Result "1-0"]
1. e4 c6 2. d4 d5 3. exd5 cxd5 4. c4 Nf6 5. Nc3 Nc6 6. Bg5 Qa5 7. Bd2 dxc4 8.Bxc4 Qb6 9. Nf3 Bg4 10. d5 Nd4 11. Be2
(11. O-O is obviously much stronger.)
11... Nxe2 12. Qxe2 Rd8 13. Be3 Qa5 14. O-O-O
(Normally I'd call such moves aggressive, but here white wants his king on this k-side.)
14...Nxd5 15. Nxd5 Rxd5 16. Rxd5 Qxd5 17. Rd1 Qc6+
(This goes with check, a luxury black shouldn't have.)
18. Kb1 b6 (slow. 18... e6 19. Bxa7) 19. Qa6! Qc7 20.Bf4 Qc8 21. Qa4+ b5 22. Qxb5+ Bd7 23. Qa5 Qb7? (greedy and slow.)
24. Ne5! (The Tasc R30 was showing +2.38 with a search depth of 03/07, while the Polgar was showing 0.03 on its 6th search iteration. For the record, the Tasc was calculating at 3330 positons /sec here.)
24...Qe4+ 25. Ka1 Qxf4 (within a couple of seconds came a M4:) 26. Qc7 Qf5 27. Rxd7 Qb1+ 28. Kxb1 a6 29.Rd8#

As you can see this sees a few new entrants. One of my personal favourites is the underestimated Master. I think this may be under-rated on the rating lists due to its Ponder-bug which switches off every time you start a new game. I was very careful to make sure it was ON throughout the tournament. This thing has some tactical fire-power, like its bigger brother - the Atlanta.

excel.}

Now for games 41-60.
This introduces two new dedicated chess computers: The Diamond II and the London 68030!
For my money the London 68030 is my personal favourite to win the tournament considering how well the Vancouver 68000 is doing - the London 68030 has hardware about 5x as fast, a better program and a better opening book.
Here are the games. A tournament table and game highlights to follow
41. Magnus - Diamond II 0.5-0.5

Thanks Carl. Excellent work. Fascinating to see the characteristics of these machines, as well as some fine Chess!

There are some great games being played, that's for sure. I'm really appreciating the different styles of the machines:
Diamond II - loves to push pawns
Tasc R30 - great endgame play, sacs pawns in the opening / middlegame
London / Vancouver - sound pawn play, but not passive
Master - tactical wizz, much weaker positionally
Magnus - incredibly speculative play, very human like, really feels like the real thing
Polgar - strong positionally (I wish I had its bigger brother the RISC 1MB)
anyway, now for the crosstable:

Shredder is now clearly better and I feared the London 68030 might go under.

Here's boy-wonder getting beaten up:
[White "London 68030"]
[Black "Magnus age 10"]
[Result "1-0"]
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Nb8 10. d4 Nbd7 11. Nbd2 Bb7 12. Bc2 Re8 13. Nf1 exd4 14. cxd4 d5 15.e5 Ne4 16. N1d2 Nxd2 17. Bxd2 c5 18. Qe2 (18. e6! was the move we wanted to see)
18... cxd4? (18... Nf8 was called for)
19.e6! fxe6 20. Qxe6+ Kh8 21. Nxd4? A shame. (21. Bf5!! wins.)
21...Bc5 22. Qf5 g6 23.Qg4 Ne5 24.Qf4 Qb6 25.Bc3? Despite having loads of time, the London played this in 30 seconds...
(25. Nb3! Bd6 26. Bc3 Qc7 27. Qf6+ Kg8 28. Na5! wins, amazingly.)
25... b4

27. Re8!!
Well played! Although the London thought it was only 0.60 up. Even so, it shows this machine is tactically very strong.
27...bxc3 28.Qe5+ Kg8 29. Ne6! The London needed a deep 5/17 search to finally start seeing more advantage to white...+0.72
29...Bxf2+ 30. Kh1 Finally the London 68030 realised it was nearly a piece up
30...Bd4 31. Qxd4 Qxd4 32. Rxf8+ Rxf8 33. Nxd4 cxb2 34. Rb1 Bc8 35.Rxb2 Kf7 36. Rb8 Kg7 37. Bb3 Kf7 38. Bxd5+ Kf6 39. Bb7 Rd8 40.Rxc8 Rxd4 41. Bxa6 Rb4 42. Kh2 Re4 43. Bb5 Re3 44. a4 Rb3 45. Rc6+ Kg5 46. Rc5+ Kf4 47. a5 Ke4 48. a6 Ke3 49. a7 Ra3 50. Rc7 Ra5 51. Rxh7

Now the London 68030 called mate in 6

Hi Fern,
This is what I managed to get from reading the website files:
"SparkChess uses a chess engine developed in-house with negamax, principal variation, iterative deepening, aspiration, quiescence, history heuristics and transposition tables. It has an opening database with about 15000 moves. The desktop version is multithreaded."
and also:
"Our Chess AI was created to be fun and quick, not brutally strong. If you are an advanced player, you can still enjoy SparkChess’ multiplayer or by using its Board Editor and the PGN/Replay features."
The strongest personality "Guru" isn't much better than Boris but takes around 3 min per move!
I'd estimate Boris to be about 1600 elo and Guru maybe 1700-1800 elo.

I concur. I played Boris and was like playing Ches challenger 7, perhaps a little bit better.
