Subject: ICC Tournament, LambChop vs Nimzo (position)

This was an exciting game.  LambChop got an early advantage winning a pawn and
seemed to be cruising.  Nimzo sacced to get a dangerous passer, and things got
pretty unclear.  Eventually LambChop allowed(?) Nimzo to queen, thinking that it
could also force a queen with advantage.  The following position was at the end
of a tactical sequence:

[D]8/1R6/P4p2/kP1Rbb1P/1r6/5P1P/4BK2/1q6 w - -

Chop's score had been greater than +1, but here it dropped to zero.  In fact, I
think white is busted.
1.a7 was played, but that ends up getting mated by Bg3!!+.  The game variation
went 1.a7 Bg3+ 2.Kg2 Bxh3+ 3.Kxg3 Qe1+ 4.Kxh3 Rh4+ 5.Kg2 Qxe2+ 6.Kg2 Kb4 7.a8=Q
Qe1+ etc
1.b6+ Ka4 2.a7 Bg3+ is similar
1.b6+ Ka4 2.Rxe5 Qh1! wins for black I think, for example 3.Rxf5 Qh2+ 4.Ke3 Qg1+
1.Rxe5 Qh1 is similar to the above line

Question: how long for other programs to see white isn't well here?

Nimzo was showing a white advantage too, although only after a brief ponder and
its PV was not sound.

All in all, a fun day with plenty of fascination chess!  Thanks to McRiley and
co for organising it, and thanks to all the other participants.
