Subject: I could not find any mistake in this game
Here is a game between Help Bot and Easy Level. The game was equal
till 37th move where Help Bot took the pawn of Easy Level.

Then Help Bot was a pawn up and was able to win in 50 moves.

Was there any way to save the Pawn. Since GetClub do not know all end
games rules. What was the mistake in End game that GetClub loose that
Pawn.

Till 35th move the game was quite equal. But suddenly Help Bot got 1
pawn up. Was there any Tactical / Strategy mistake by GetClub?

What should GetClub had done to avoid the loss of pawn. What were the
wrong moves?

Today again the GetClub Chess was improved.

Now beginer Level will play as good as Easy Level. So no need to play
with Easy Level Just play with Beginner Level and get same strength.
And you save a lot of time.

Play with Easy Level only if you want a tough competition.

I ran this through a quick computer analysis, which
indicates that although much of the game was even,
I had a big advantage from moves 14 through 19, at
which point I blundered horribly.

Sanny, many chess programs have serious
difficulties in handling Rook and pawn endings
well. Even Rybka, in one of its recent odds
matches against GM Dzindzi., messed up a
fairly simple Rook ending!

Chess books are filled with examples, culled
from grandmaster play, in which very simple
winning or drawing ideas were rejected in
favor of some hare-brained idea. In fact, at
one time certain drawable endings were
mistakenly believed by the talking-heads to be
wins, simply because Mr. Capablanca did win
them, and fairly routinely, against "masters".

Let's jump to move 34, where I allowed a
"Rook to the seventh rank", along with other
active tries like R-h4 or R-g4:

34. Kf3

This prepares to deliver some spite-checks,
beginning with 35. Re4+. But you see, the
spite will amount to nothing, while the loss
of time (one tempo) gives me the initiative!

What ought to have happened was a pawn
race in which GetClub eats my pawns (on g7
and h7), then runs its h-pawn up the board,
while I eat the White pawns (on a4 and c4),
and run my a-pawn up the board. I have no
idea who wins, because it's too close to call.
Whichever side makes an unneccessary
move, losing a tempo, may well end up
losing the game (or throwing away a draw).

Anyway, if both sides play actively, it's
very, very close; what the annotators like to
call "equal chances".

After what happened in the game: 34. Kf3
...Rb4, Black is on top because the a-pawn
falls and that gives me an outside passed
pawn (way, way outside because the White
King is now on the Kingside).

The only way I know of to correct this kind
of problem is to *remove* the bonus your
program obviously gives for spite-checks;
spite-checks are irrelevant.

Rybka plays this ending very, very
differently, keeping the threats coming at
me like bees near a disturbed hive!

As of 37. c5, the game is already decided.
Any exchange of Rooks along the rank will
result in a won King and pawn ending. Even
so, after my 38. ...e5, the move 39. Rf5 was
much better than going down without a fight.
