I don't think I managed to make my point but I don't give up that easy.

About Rxe6 I like to quote myself...

  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.

  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.

I am still stand behind the Rxe6 principal. The fact Ferret and Crafty
played the game after 1.Rxe6 fxe6 is not very convincing to claim Rxe6
loses.

Next, *IF* playing the position by 2 computers is a topic then it should
ALSO be played from the start position. After all white is a pawn down. If
black is able to defend he simply will win the game *TOO*.

I picked another example to prove my point. Also a tactical one for
reasons of clearness. Rebel10 anti-GM is NOT about tactics but sometimes
it certainly has some nice side effects.

I deliberately do not pick a positional example (although I personally
believe they are MUCH more important) because you can always argue
about the moves as we all have our different taste. So a pure tactical
example and this time there can be no confusion about the key-move.

This game fragment comes from the WCM Munich 1993, Hiarcs - Genius.

Rebel10 (without anti-GM) finds Bxh6 on ply-7, score 1.19, time 0:27
Rebel10 (with anti-GM) finds Bxh6 on ply-5, score 1.23, time 0:01

Note that anti-GM is not about tactical tricks like extra extensions,
just some specific positional knowledge.
