May-27-06  blingice: Soooo close. Quite an interesting endgame though.
May-27-06  alexandrovm: computer endings :)
May-27-06  Knight13: Yes. Interesting endgame. Black might have won if the pawns were not doubled.

Again, "computer endings " :)

May-29-06  Chuckles: I don't understand black's 153..Ka1. Can't he win by Kb3?
May-29-06  LoFarkas: It could have. This tablebase is proof: http://mx2.lokasoft.com/uk/tbweb.htm

Set up the position and it spits out the moves for the forced win. (mate in 24). Incidentally, Kb1 is also a forced win.

May-30-06  Chuckles: So why would Jonny make that move? Is it not playing with 5-man tablebases?

These computer endings are funny sometimes. I always think of engines as being so efficient, like going for shortest mates, etc. But here White can have an instant draw just by 158.Nc3, and instead it plays this little Ka3 waiting move and draws in two more moves :)

Jun-09-06  neosystems: Nice Miniature ^_^
Feb-05-07  IMDONE4: dont the operators usually offer a draw if the position is a dead draw?
Apr-04-07  dpacaba: <Chuckles: I don't understand black's 153..Ka1. Can't he win by Kb3?>

Very interesting, I may not be good at endgames but placing a king in front of a pawn that is about to be promoted is not a good idea.

How could a computer like Zappa miss that in an endgame?

  kevin86: Strange finish:of all games of N vs PPPP,this is not only twice as long as any other,but also the only draw.

Are these the kind of computers college basketball coaches study from?

Game reminds me of the Timeout/foul mentality of said coaches.

Jan-17-09  WhiteRook48: computers hate drawing games it seems. That way they'd probably play on in this drawn ending.
Feb-07-09  WhiteRook48: but insufficient mating material calls
Feb-15-09  WhiteRook48: Zappa must have worked hard for this draw
May-03-09  WhiteRook48: boring!
