Default Game with Rybka Drawn. !!!

Today I tried a new game between Normal Level (100 seconds/move) &
Rybka (5 seconds / move) And the Game was Drawn by Repetitive moves.

Yesterday I said GetClub is 20 times weaker than Rybka, Since Normal
Level which thinks 16 times more than Rybka at 5 seconds / move plays
as good as Rybka.

I showed a game where the game was nearly equal but later Rybka was
able to break the defence and win in 43 moves. People said Rybka won
the game and It was only 1 game after the game was improved. So they
do not bilieve Rybka at 5 seconds plays as good as Normal Level.

So now you all agree Normal level plays as good as Rybka at 5 seconds/
move?

The game was ended in just 29 moves.

What do you think How is GetClub going.

A party time for GetClub as this is the first game where GetClub was
able to Draw with Rybka.

So now Normal Level plays as good as Rybka at 5 seconds / move. Do you
all agree with that. So GetClub is 20 times weaker than Rybka. A move
Rybka thinks in 1 second. GetClub needs 20 seconds for finding that
move.

That roughly translates to saying that at equal time allocation Rybka
will see approximately 4 plys deeper than Normal level.

It isn't clear how the ply depth of Getclub scales with increasing time.

Yesterday I said GetClub is 20 times weaker than Rybka, Since Normal
Level which thinks 16 times more than Rybka at 5 seconds / move plays
as good as Rybka.

It managed to hold on in a fairly dull game, but one swallow does not
make a summer.

Nh5 is well off the pace. Too easily countered.

Getclub had slight winning chances here so it isn't too suprising that
Rybka was prepared to go for draw by repetition.

26. a5 looks about the most direct line of attack

27. Bc3-e1{24} Nh5-f6{120}
28. Be1-c3{20} Nf6-h5{82}
29. Bc3-e1{22} Nh5-f6{172}

move.


We don't know that. It is quite likely that whilst Rybka will gain an
extra ply of search for every doubling of the time allowed your program
will very likely scale considerably worse.

We can only conclude from this test that it is possible for getclub
"normal" to hold Rybka 5s to a draw at least once.

GetClub with Black pieces was at Advantage. Why was Rybka not able to
take advantage of White pieces and get into a weaker position?

Is there any wrong move by GetClub that it was unable to win the game?

What should have GetClub done to win the game. Why it just draw the
game?
