As computers "understand" things, it is important
to keep both Bishops, as that gives a nice bonus
for having the Bishop-pair.

As for lowly humans, it's just a fact that a "good"
Bishop like this one is superior to a Knight, due to
its longer legs -- it's ability to get around the board
quicker -- and ability to attack from a safe distance.
It is, in essence, the same reason a Rook is
superior to a Knight.

In the game, I did snatch a couple of pawns
like this; but the point is, White could have
forcibly trapped the Knight -- winning a full
piece instead.

As I pointed out in my earlier comments, the
real problem for Black was that his Knight was
doomed as early as move 25 (had I spotted the
correct follow-up to p-f4, which was B-c1). The
secondary (i.e. less important) threats were the
snatching of pawns, and the doubling of Rooks
on the seventh rank.

Bishop and Knight?

otherwise 25..... Ng5 26. Rxb7 27. Rxe4 Rxa7
and White will be a pawn up.

Here are a few comments based on Rybka (the free version)
analysis:

5. c5 lost White a third of a pawn, apparently due to the
/loss of time/ of this and the forced cxd6 next move; Black's
reply, ...Bg4, gave back most of this, however.

7. ...the manuever ...Na6-b4-d3 was possible, snagging the
fianchettoed Bishop in exchange for a mere Knight.

8. O-O was possible, despite the outright loss of a pawn.
I did not examine this in detail to see "why".

14. ...Qc7 was a significant error, losing Bishop for Knight.

18. A better plan for White was f3 and then e4. My clever
move, Nh6+, was a significant error-- wow!

21. ...f5 was necessary, here or on Black's next turn.

24. ...Nh3 was essentially "the losing move"; the Knight can
be trapped as early as move 25, with correct play.

25. The overly-defensive ...Rb8 was awful; correct was ...Ng5.


Throughout this part of the game, I (as White) overlooked
the fact that I could /safely/ trap the Knight by playing f4
and then retreating my Bishop to c1 to cover f4 and
thereby enable K-g2 without a nasty ...Nxf4+ in reply.
Thus, my position score keeps going up and then back
down, as I scoop up a pawn or two when I could have
instead gobbled the scrumptious Knight at several different
points.

32. Here again, I had the Knight cornered via Bc1!, but in
the game Black had one final chance to extract his Knight
and fight on; the terrible ...R/f-c8 clinches the game for
White, for even the c-pawn is immune due to back-rank
mate threats.

34. ...Rb8 was terrible; after ...Ng5 instead, White's Rook
is taken out of play for a good long while though still a
piece ahead.


GetClub's Master level is painfully slow, but at least it
did not lock up and refuse to move this time around.

Note how Zebediah has used his chess engine to push
the Advance level's rating down to ridiculous lows-- lower
than even some of the much, much weaker levels. Now
he seems to have switched to giving the Master level the
same treatment.
