Default Very Difficult Games.

Below are a few Games won By Help Bot at GetClub. The Games were
played with Normal Level. Despite such a hard program Help Bot managed
to win the games.

Now it is very difficult for me to understand why Help Bot win and
GetClub Lost the Matches. For me all moves looked correct only after
few moves I found it lost a pawn/ Knight in exchange.

Tell me the weakness in Games I type Below. And tell me full
explanation of how to avoid those mistakes. Help Bot used to think 2
min/ Move So you too have to study the moves for 4-5 min to find why
Help Bot played that move.



I am not always at my computer when the GetClub program
makes its moves, so you can't just assume my times are my
actual thinking times.

In particular, one Windows "tab" tends to lock up quite often,
and I have no choice but to wait until it unlocks itself before I
can switch to the chess game to consider my reply.



I was thinking now GetClub has improved a lot and will win each game
against Help Bot. But Help Bot has again prooved he is still smarter
than GetClub Chess.

Here are THREE Games with time in seconds against each move.

In the above game the program walked right into a pawn
fork with 17. Qf4, so there is no great mystery as to why I
won.

got chased around until at last, it was pinned to
the White King.

43) Qb1-b2(84)



In this game, White got a piece inextricably trapped
in a self-pin by 12. Bxa7. The depth of search needed
to "detect" this using brute calculation may be too
much for the GetClub program, but it is obvious to
any decent human player. In fact, the whole idea of
Q-a4 in order to attack such a pawn is wrongheaded;
this is the same mistake Bobby Fischer made in his
first game against Boris Spassky in 1972; you get in,
but you can't ever get back out.
