Was playing the following against Hiarcs 8. I am White:
1. e4 c5
2. Nf3 Nc6
3. Nc3 Nf6
4. Bb5 Nd4
I intended to continue with either e5 or d3. But the move the computer
likes best for White here is Ba4.
Can someone explain why??? Doesn't do anything I can see except waste a
move.
Thx.
John

You should always try to keep both your bishops as they cooporate well
together, only trade a bishop for a knight when you have some extra benefit
like ruining your opponents pawn structure.
In this case if you allow Nxb5 you just lose the bishop pair which is bad
already and on top of that you also get a badly placed knight on b5 which
will have to retreat eventually with loss of tempo.

No offense, but this is way too oversimplified.
While it's true that in many positions, a pair of bishops confers a
small advantage (albiet, in my opinion, an advantage which many weaker
players are incapable of taking advantage of), it's important to
remember that whether or not the bishop pair is an advantage depends a
lot on the pawn structure.
There are times when you are happy to give up a bishop for a knight --
for example, when that bishop is hemmed in behind your own pawns, or
when the pawns in the center of the boards have been locked with no real
chances for pawn exchanges.
Part of the reason for the bishops being considered advantageous is
that, sooner or later, most games feature enough pawn exchanges to open
the position -- but if you believe you can keep the position closed, it
is usually to your advantage to keep knights rather than bishops.
There is an excellent discussion of the relative merits of knights vs.
bishops in Jeremy Silman's "How to Reassess Your Chess," complete with
lots of examples from master-level play.

The other time the bishop should be traded for the knight is if you are
clearly ahead in development and can exacerbate the advantage (i.e., a 3-1
edge traded for a 2-0 edge in developed pieces, etc.)

You are right Ba4 is not that a good move. Theory gives e5. However, I
would suspect that you are not giving your computer enough ply scope.
Fritz 8 goes for e5 once it gets past about 11 ply. Big hash tables, fast
computer and lots of memory and time tend to produce better chess for
Computers... Humans on the other hand use boooks and experience!
Pragmatically if you look at Ba4 it removes the attack from the knight and
supports c2.

With his last move, black threatens to take the Bishop on b5 with his
knight and white doesn't want to lose his pair of bishops so early.
(Some people think that bishop, especially a pair of bishops are a
little better than knights)
