This move, N7f6 is better than what I proposed. I realize that most the
computer programs will consider this quite hopeless for white now. But
just to satisfy my curiousity do you mind if we continue on a bit.
Does the next set of moves look reasonable to you.

7 ...N7f6 8.Nac5 Rg8 9. Nd3

We've come 9 moves from the original position and part of my assessment on this
requence of moves is pretty well in line with what Bruce Moreland posted a while
back that he spoke to Im's and one Gm and they said it was a complicated
position. So Rxe6 does stir up a hornet's nest. But despite the high eval
computers give to black for the resulting position the position does have
that element of an uncastled black king. It is well sheilded by by its pieces
but how will black undertake anything, given its pieces being preoccupied
with sheilding the king? That's my reasoning for playing on a bit.

After white plays Nac5 how would your programs autoplay this game out?
Would they manage to keep building on Black's big material advantage?

If the computers are correctly assessing the position now with the
black king in the middle then I'll join Bob in saying the move, while
complicating things, is nevertheless unsound. Ditto for agreeing with
fca who started this thread.

Also has anyone played the game out using Bh6 or Qa3 as the first move?
After 9 moves of play in these lines what is the eval? That could save us time
too as the original intent of this thread was to see if Rxe6 was any
worse than other first choices. If other first choices were "losing"
also then perhaps the entire example is the wrong choice, as fca
originally suggested.

Either way the verdict falls I'm enjoying analysing this position. Puzzles
have always intiqued me and chess seems to have an unlimited supply of them.
