Poor analysis by Fritz 8!

Pawn endgame:

On ChesBase Server I plays today bullet. In the fallow position my Opponent have
only 3 second for the rest. It is clear that I give no a draw in such a game - I
thinks it is ok in Bullet/Blitz.

For everyone human is on easy (simple!) now to seen that black will win here
(normally).

But for most programs it is very hard, to gives a correctly winning line for
black.

Fritz 8 is a little big BLIND here (hello Frans Morsch):

[Event "Wertungspartie, 1m + 0s"]
[Site "Großer Spielsaal"]
[Date "2004.04.10"]
[Round "?"]
[White "Eduard"]
[Black "Opponent"]
[Result "1-0"]
[ECO "A43"]
[WhiteElo "?"]
[BlackElo "?"]
[Annotator "Nemeth,Eduard"]

[FEN "8/5pk1/3R2p1/2r1p3/4P2P/5PK1/8/8 w - - 0 47"]
[PlyCount "5"]
[TimeControl "60"]

Time here: white here 9 seconds, Black 2,7 seconds:

47. Rd5 {My Opponent offers a draw 0} Rxd5 {2} 48. exd5 {0} f5 {0} 49. d6 {
. ' 2} 1-0

(Time, and 1-0)

On My P3 600 MHz:

Eduard vs. an Opponent, Bullet 1m + 0s
