I Wonder playing Chess with computer as now it gives twice better
moves.
Play at : http://www.softtanks.com/chessgame/Chess.html
The game now uses better technique which made it about twice better
while making moves in same time. So the Beginner level will also give a
good challenge to new players.
However those a bit better at Chess should start playing with Easy
Level and then switch to Normal Level.
I have not yet played with higher levels but sure they will give heavy
competition.
Play at : http://www.softtanks.com/chessgame/Chess.html
I thank to all people who helped in finding mistakes. I hope now most
of the problems have been sorted out. If any problem still there inform
me and that will also be removed soon.
Play first with Beginner Level
If you win then beat the Easy Level
If you win the Easy level also then Challenge the Normal, Master &
Advance Levels.
(All Levels are free to Play)
(Multiplayer games are also availble) I played two games with my friend
Online.
Bye

> If there is any strategy mistakes it is doing please let me know it.
I'll go through the game from end to beginning.
Well, it shouldn't make illegal moves, just as right in the end it made
24...Kxh7 which allowed me to capture its king.
Putting that aside, moving into a forced mate in two on move 23...Rf7
is something that shouldn't happen. What's the search depth?
A key mistake (or at least one of them) was 22...d4. That gives white a
forced mate in 12 moves. I don't assume that it sees that, but breaking
a just a fine pawn chain, limiting the rook's movement options and not
moving the bishop into game via a6 should be enough to justify 22...Ba6
as a much better move.
And then there was this 16. h3 Bxc5 17. hxg4 h6 18. dxc5 Rxa5. It gave
me a knight and a bishop for two pawns. It could have avoided this by
just saving the knight by moving it 16...Nh6.
Right at the beginning you can see that the program has never heard of
opening theory. The first move is 1...e6. French Defence, OK. But my
point is that the second pawn move does not come until move 9...a5. It
should open its play a bit more. Now it got really stuck in its
positions.
I hope this helps you develop the program further. :)

I like the queenside pawn storm, knight sacrifice, and the mating
attack. It's actually a graceful solution to this chess engine.

This game was slightly better, but it took way too long. Your site says
Easy means "30 sec / move", but it usually thought for 2-5 minutes.
Master says "2 min / move". Either Master is the same as Easy, or it
would take much more than the 70 minutes Easy took. I again had to
capture your king instead of mating it.
I'm done with this--improve its performance if you want repeat traffic.

Riiiight. Your engine took 35 min, and broke the rules of chess.

Yes there was a restarting problem that was rectified. If it again
restarts let me know it along with the moves. (This problem was due to
typing mistake by one programmer).
If you find any mistake let me know it and it will be removed.
I do not think you could easily beat it's normal and master level can
you show a game where you have beaten its master level easily?

I tried to play the same game but it changed its move at 3rd move here
is my game
1.e4 e6 2.Nf3 Nf6 3.Nc3 Bc5 (instead of Bb4)
Played at: http://www.softtanks.com/chessgame/Chess.html
The interesting point of this game is that it makes a new game every
time you play with it So you cannot win by making same moves.
If there is any strategy mistakes it is doing please let me know it.
Bye
Sanny.

I thought I'd play a quick game before I go to sleep. Instead, the
engine wasted almost an hour of my time even at the Easy level and in
25 moves. :/
It did seem to try anyway and even get a grasp of something at some
points.
I know how boring it can be to gather some debug data for a program so
here's the game in PGN:
[Date "2006.5.11"]

15.Neg5 f5 16.h3 Bxc5 17.hxg4 h6 18.dxc5 Rxa5 19.Qc3 Ra4 20.gxf5 hxg5
21.Bxg5 Qd7 22.f6 d4 23.Qd3 Rf7 24.Qh7+ Kf8 25.Qh8# 1-0
Actually the last moves were 24...Kxh7 25. Rxh7#. I hope you are able
to extract some helpful information out of this anyway. Please do not
comment my playing but only observe how the program plays - I knew I
was playing a weak opponent and wanted to try some things I normally
would consider twice.

I don't think Sanny would know what to do with debug data, anyway.
He's been posting here about once a month saying his program now plays
much better chess and every time, somebody posts about how it dropped
a piece to a pawn fork within the first five moves.
As far as I can see, Sanny's approach seems to be to hard-code
positions into the program so it doesn't make the same mistake twice.
Unfortunately, there are so many possible mistakes in chess that this
is doomed to failure.
Dave.

It still plays terrible even on master-level. I could hardly spot any
difference between lowest and master level. It gives away pieces and
queens unforced and plays more or less randomly. Despite that it
regularly restarts the game.
