Can you see what mistakes GetClub made?
Let's look at the very end of this game, shall we?
White walked his King up to threaten a mating attack,
and Black "saw nothing" and sauntered over to the far
end to snack on some pawns. Even when the mate is
just a few moves away, Black still "saw no problems"
and chowed down some more.
Look at 45. Re7; this move attacks an undefended
pawn, intending to munch next move. How did Black
reply? He ignored the threat completely, moving his
Rook to an open file. It appears as though Black is
not looking at the opponent's moves at all, but just
doing his own thing (here, eating pawns whenever
possible). Only when it was mate-next-move did we
see the Beginner level halt the game by resignation,
apparently noticing the problem.
Now, I understand that Beginner level does not
exactly "go deep", but it should nonetheless at least
be *attempting* to minimize the damage by defending
attacked pawns and pieces when possible.
This indicates that there is a serious problem still
with elementary tactics. No chess program -- even
a Java applet on Beginner level -- should be having
such problems if the programmers have implemented
tactical "check and capture" search extensions
correctly. Heck, my computer will often go up as
high as 8 or 9 plys in under a second, and that is
finished searches, where the check and capture
extensions may have gone much, much deeper.
-------------------------------
But this game does show one positive thing: if you
replay these moves on a much stronger program
you will find that the score went back and forth, the
two programs apparently being reasonably closely
matched. When one program is vastly superior, the
trend generally is that it grabs the advantage quickly,
and then increases it on almost every turn; that is
certainly not what happened here -- far from it.
