Some information about the Rxe6 position. The position comes from a
magazine and was commented that Bh6 is the best move. The magazine
gives the followings points for selected moves...

C1H6=10 E1E6=08 D4E6=07 H3H6=03

So 10 points for Bh6
8 points for Rxe6
7 points for Nxe6
3 points for Qh6

Now I agree with the magazine that Bh6 is the best move and so I want
Rebel to play it. But it doesn't happen. What happens is...

#1. Rebel likes Bh6 from the very start, sofar so good.

#2. Then surprisingly it comes up with Rxe6, fine with me too!

#3. Then the score of Rxe6 (at longer time control) drops to -1.00
again.

#4. Then Rebel switches to the in my opinion ugly Qd3 which I consider
as a worthless move doing nothing to keep the attack going on and is
simply dead wrong playing a GM.

Whatever the discussion if Rxe6 is a good or bad move IN THE END (for
this position) is *not* important. What *is* important is that white
is a pawn down. For that white has compensation as the black position
is under great pressure. If black is able to defend and escape from
white's attack black ends up with a pawn up which will give black good
winning chances.

So white's attack must go on by all means.

Meaning to say:
Bh6 fine!
Rxe6 even better
Qd3 horrible!

Rebel10 with anti-GM plays Rxe6 and I am very pleased with it. Taking
into consideration that white is a pawn down and the white attack must
go on by all means because of that, Rxe6 will give any GM a very hard
time especially on short time controls and that's exactly *one* of the
goals of anti-GM.

Maybe(?) Rxe6 is not the best move playing against another computer and
Qd3 is simply better, but it is my opinion that Qd3 against any GM is no
option at all.
