|
Today a little improvement was done in GetClub Chess.
I played Easy Level(30 sec / move) vs Rybka (6 sec / move)
The game was equal till 27th move then Rybka got a pawn up in
exchange.
Since Queen and other major pieces were gone till 30th move. The game
went into End Game Phase.
Since Rybka was a pawn up it was able to get the Queen in 48th move
and then found a Mate.
It was for the first time Easy Level was able to postpone game to End
game till 49 moves.
Since Easy level was thinking 30 sec / move and Rybka was thinking
just 6 sec / move. GetClub was taking 5 times more time.
If GetClub take 10 times more time then it will play as good moves as
Rybka does.
Rybka is just 10 times stronger than GetClub.
Here is the game.

In this game for the first time Rybka had no way to get a win in the
middle game. It has to play till end game to win the game. GetClub
gave no opportunity for a quick mate.
If GetClub is given 10 times more time than Rybka it will play as good
moves as Rybka does.
Now Help Bot and Taylor Kingston will find it much difficult to win
the Beginner & Easy Levels.
Lets see how the players score at GetClub after the todays
improvement.

Its not the rating that has to be divided by 10. Its strenth.
Whith every twice strength Rating goes up by 100 points.
So for Twice 2 times strength Rating +100
For 4 times strength Rating +200
For 8 times strength Rating +300
For 16 times strength Rating +400.
Since Rybka is 10 times stronger. (It takes 10 times more time for
GetClub to find a move which rybka finds in a given time.) Rybka
rating is +350 higher than GetClub.
Since Rybka Rating it 3000, The Rating of GetClub under same time
control is 3000 - 350 =3D 2650.
So Normal Level is Rated 2650. Acording to this estimate.
Normal Level (2 min / move): 2650
Easy Level (30 sec / move) : 2450
Beginner Level (8 sec / move): 2250
So this estimate is giving +300 rating to GetClub Chess.
However the real Rating is 300 points lower than it.
The real Rating of GetClub Chess is.
Beginner: 1900
Easy: 2100
Normal: 2300
Master: 2500
So I think the Rybka version I am playing is not having a rating of
3000 But it has a rating of 2700.
Incase the Rating of Rybka is 2700 then it gives correct rating of
GetClub.

Still the wrong word. What you are looking for is "speed of
calculation". For chess strength you then also need to do something
useful with the calculations, in particular with regards to evaluating
positions. If you were actually trying to improve GetClub (which you
clearly are not really trying to) you would work on the positional
evaluation function.

Let's see. If Rybka is 10 times stronger than GetClub, and Rybka is
rated 3000, then 3000/10 = 300. So GetClub at its best is rated at
300.
Sounds about right.
