You know, I don't think we can get any sort of meaningful data from playing a bunch of 40-moves-in-10-second games with Joker80. To wit, I observed that Joker80 did not defend that well as Black after the 1. e4 d5, opening, so I set up a match of 100 40 moves/10 seconds games with the 1. e4 d5 2. exd5 Nb6 opening (observe that White can't hold on to the pawn), and got the following result:

Win: 47.2527% Loss: 35.1648% draw 17.5824% score 56.044%

So, then, looking at the games I saw Black wasn't defending as well as he should, so I ran 100 games with three times the time: 40 moves in 30 seconds. I got considerably different results:

Win: 40.8602% Loss: 45.1613% draw 13.9785% score 47.8495%

('score' above is White wins + Draws/2)

Here, we see Black defends a lot better and White doesn't win nearly as often.

Point being, on my system (Core 2 dual, 1.5 ghz), the 40-moves-in-10-seconds games does not give us enough time to play well enough to determine whether a given opening is any good. 1. e4 d5 2. exd5 Nb6 is a fine defense for Black, but we need more time for each game to see that.

As an aside, one of the 30-seconds-for-40-moves games has this pretty checkmate:

1. e4 d5 2. exd5 Nb6 3. Ne2 Nxd5 4. f3 c6 5. c4 Nb6 6. c5 Nd5 7. Bc2 g6 8. Cj3 Ad7 9. Qd1 h5 10. Nhg3 Ke8 11. Bf2 Nb4 12. Ba4 b5 13. cxb6 axb6 14. O-O Ni6 15. d4 Qd6 16. Ne4 Qe6 17. Ci5 j6 18. Nf4 Qc4 19. b3 Qa6 20. Axb4 jxi5 21. Bxc6 Kf8 22. Bxd7 Nh4 23. g3 Cj6 24. Axa6 Cxj2 25. Nxg6+ fxg6 26. gxh4 Cj1# 0-1
