I borrowed your chess board design, with a few tweaks. =) swa q 22:14, 3 November 2008 (UTC)[reply]

World won!

I'd like to think my last-minute strategy of 30 October 2008 contrubuted a bit to this victory! Oliver Fury, Esq. message • contributions 22:14, 14 December 2008 (UTC)[reply]

It definitely contributed :) J.delanoy ^gabs _adds 05:24, 15 December 2008 (UTC)[reply]

I just did a computer analysis of the ending position and it says J.delanoy was up slightly (1.4 points). You had to find the right moves though. It suggests a possible continuing line of:

46. Nc6+ Kf5

47. Ne7+ Ke6

48. Rxf4 Kxe7

49. g4 hxg4

50. Kg3 Rg1+

51. Kxf2 Ra1

I dunno. I think ending up with K x Ne7 seems a bit implausible for a human. If I were black, I'd defend that one pawn rather than going after the knight. J.delanoy ^gabs _adds 19:23, 15 December 2008 (UTC)[reply]

If black tries to defend the pawn white can take it anyway, forcing black to take the knight:

46. Nc6+ Kf5

47. Ne7+ Ke5

48. Ng6+ Kf5

49. Rxf4 Kxg6 (if 49. Nxf4 then black plays Rh1+ and gets a queen but the computer still says white is up slightly)

Fun game! =) swa q 19:46, 15 December 2008 (UTC)[reply]

By all accounts, if Black gets a queen, I lose. Period. Way too much power there. I would have to keep Black in check almost continuously while simultaneously queening my own pawn, or else Black would bring immense pressure onto my King and my pawn.

I guess it's the honour system keeping people just using a computer to beat J.d ? (& vice-versa) –xeno^talk 14:22, 20 August 2009 (UTC)[reply]

It's the same with any online or correspondence chess. If you're sitting with your opponent you can't know for sure if they are using a computer or not. Some online chess servers have ways of trying to detect this cheating, but in general it's just the honor system. swa q 15:25, 20 August 2009 (UTC)[reply]

Not to give the opponent any ideas, but it looks like White can win a pawn and screw up The World's pawn structure.

8. e5 Nd5 9. Bxa6 bxa6 10. bxc5 followed by b2-b4 to protect the pawn. c2-c4 to chase the knight may also be effective.

It might be even better to keep the bishop, which is much better-placed than the knight, and go for a kingside attack. I still think 8.e5 is stronger than other moves because O-O or Nc3 gives space for ...d7-d5. The threat of check at h7 leaves open another possibility for a central advance, one which intuitively doesn't look right to me but can lead to advantage for White.

8. d5 d6 9. Nc3 (maybe c4 here?)

but if 8...exd5 9. exd5 Nxh5 10. Bxh7+ Kxh7 11. Qxd5. White threatens 12. Qh5+ Kg8 13. Ng5 and a quick mate. Black has 11...Qf6 but he's still in trouble.

Anyway, I might have some fun defending as black from any of these positions. Soberknight (talk) 23:57, 16 March 2009 (UTC)[reply]

It continued with 8. e5 Nd5 9. Nc3 Nxc3 (10. Qxc3 imminent, with our c pawn in danger). Can we proceed with 10. ... b6 or d6? Alexius08 (talk) 01:15, 15 June 2009 (UTC)[reply]
