Complete Recorded Game:

It looks like White played silly but it was Master Level which does
long calculations. Was there a way by which White could have avoided
such traps.

In the begiining White was a pawn up, But in just next 8 moves
zebediah ruined whites advantages. Was there a way for Master Level to
avoid this loss?

On average Beginner Level sees till 6 ply

But sometimes I have seen it go upto 8th ply also.

Play a game with Beginner Level
http://www.GetClub.com/Chess.html

I am sure you will see atleast 1-2 moves reaching 7-8 ply.

Well my Computer is P-IV 2.5 GHz and this is a comman configuration
these days.

What do you mean by a ply: Are you considering both Black & White
moves or only one players move.

On my browser the Beginner Level goes till 7-8 ply {each players move}
and makes move in 10 seconds.

You're either lying or you're somehow having a completely different
experience with your program than anyone else.

A ply is a move by either Black or White. So twelve ply is six moves
by White and six by Black.

I'm sorry but I just don't believe you. Nobody else is getting
performance anything like that from your program.

Well, sure. Because, for starters, it can't keep it's extra pawn.

Secondly, after it drops one pawn, the other two will become very weak.

Thirdly, black is ahead in development.

Fourth, white has abandoned the center.

> 7.Bb2 0-0

Sannybot puts the bishop on a square from which it will have a hard time
achieving any activity.

Sannybot is neglecting it's development. It's far more important to get
the king to safety than to activate the queen rook. Here, also, it
displays an inability to see more than a few moves ahead. The rook never
does anything on d1, and Sannyboy is oblivious to the threat to c3.

Incidentally, you're struggling with basic notation here. 10. ... Ne4 is
ambiguous. Please learn proper chess notation.

> 11. Qe3 Na4
> 12. Ba1 Nxc3

12. ... Nxc3 is also ambigous.

> 13.Bxc3 Nxc3
> 14. Qd2 Qxa3
>
> One more Pawn gone. Black is 2 pawn up.

More important than the pawns, however, is the fact that white is
completely undeveloped, and his kind is exposed. unsurprisingly, your
program misses even simple threats and makes a superficially aggressive
move.

> 15. Qd6 Qb2
> 16. Ne4 Qxf8 {No other move left for white}

And here your ability to do chess notation completely falls apart.

The actual game continues 16. d3 Ne4 17.Qxf8+.

This is the fundamental problem. You seem to think that because Master
Level takes a long time to think, it is looking far ahead. Clearly, that
is not the case.

Your program does not appear to be seeing more than 4 ply or so ahead,
if that. A program like Crafty, on my five-year-old computer, sees 4 ply
ahead in under a third of a second.

You need to figure out that your program is doing with all the time it
takes to make its moves, and fix it so that it's seeing further ahead.

All this chatter coming from you about making the program
stronger-but-slower or faster-but-weaker misses the point. Your program
is not making effective use of the time it has, and the result is
abysmal play. It the amount of time your program usually takes at even
intermediate level, it should be seeing at least 12, possibly as many as
15 ply ahead. It's not.

Figure out why, and you'll have a program that doesn't stink.

Hehe. I used to love playing that position as Black against the
Kasparov's Gambit computer program about fifteen years ago. It would
also get into a terrible mess playing the black side of the closed
Lopez.
