GetClub was twice improved today still it lost to Jester.

Jester found a Mate in 8 and win the game.

I could not find any wrong move by GetClub but still it lost the game.

Can you spot the wrong moves?

The Score was +ve for GetClub at most of the time but suddenly Jester
advanced its pawn towards the king and get 1 pawn up. And the King got
trapped.

Can you find which move of GetClub is wrong?

Excellent question.

But first, let's back up to move seven;
...c4 was a horrible move, and this is why
the question of "what to do after Qg4"
comes up.

Now, which is worse: the dark-square
weakening of ...g6, or the inability to castle
after ...Kf8? That's a tough one. It seems
to me that both cases give White a huge
advantage, so it boils down to a question
of who is doing the attacking, and who the
defending?


> How much penalty should be given for a weak square?


Why not try a very small penalty, and if
it needs enlargement, you can make the
adjustment later. OTOH, if you make the
adjustment too big, people will beat Get-
Club like carrots, and you won't even
know why. Tactics always take
precedence.

Castling to the other side is illegal,
because you can't legally move the King
"through check" (across any attacked
square).

An alternative to castling King-side would
be the legal move ...Rg8.

This is okay, so long as Black immediately
exchanges Queens via ...Qc7-d8, but White
need not cooperate. As we saw, Black was
quite unaware of the looming danger to his
King.

No. Black is getting mauled here. The
pawns on the other wing are largely
irrelevant-- a mere distraction from the
real issue. However, the maneuver
...Q-a4xa3-e7 could work out okay, if
White attacks very s-l-o-w-l-y, having no
clue what he's doing.

Have a look at 16. ...b4!, where Black
at least attempts to fight back.

Instead of removing this opening I have added 6...Ne7 as you
suggested.

After 6...Ne7 Black can Chastle 0-0 when Queen comes to g4.

Great Analysis. Now it would be very difficult to win Beginner Level.

Only 2 correct moves else the f7 pawn will get killed.

8.... g6 (Weakens f6 square?)
8..... Kf8 (stops King Chastling?)

Which is bigger error weak square or stopping the Chastling?

How much penalty should be given for a weak square?

If it Chastle to other side the Pawn f7 would be killed.

And if it saves f7 with Rook then Queen will go to g7 attacking the a7
pawn.

So it Chastled on king side.

So thats a good move.

You clearly need to increase the rate of
"improvement" by a factor of x-squared minus
y-to-the-nth power, square-rooted, over z-
cubed plus the speed of light in a Hoover
vacuum times the TK-factor.

This move needlessly weakens the dark
squares (i.e. f6). Believe it or not, in some
positions like this Black is better off playing
...Kf8.

Without sight of the board I can tell you
that this is suicidal; there are no defenders
of the King-side dark squares, thus it is
just about time to call for the coroner and
pick out a casket.


> 14. Ra1-b1{14} Qc6-a4{30}


Excellent positional move! White's Queen-
side is boxed up, and were it not for the
minor detail of getting checkmated, Black
would perhaps be in swell shape.

Sanny, I would suggest you simply remove
this opening from GetClub's arsenal. The
program should attempt to avoid closed
positions, and instead focus on playing the
more open ones.

But for the record, the move 6. ...Ne7
would have avoided the ...g6/...Kf8 dilemma
which occurs after White plays Qg4. Black
can then sacrifice the g7-pawn and the h7-
pawn as well (after ...Rg8, chasing White's
Queen). White, of course, is not obligated
to play Qg4 in this case.

Another idea would be to completely
ignore the misplaced Bishop on b5, and
complete development. For instance:

7. ... Ne7

8. Qg4 O-O

9. Bh6 Ng6

Again, White is in no way obligated to
play Qg4 in this line.
