Subject: An exchange sacrifice...

I have recently come across the following position,

/r5k/pp2qppp/2b/n/2pPr/P1P1PQ1P/1B4P/1B2RRK/

with white to move.  It will be white's 21st move.  I have let crafty run and
analyze this position for over 2 hours, and it returns a value of over +2 for
white.  However, I don't think that crafty understands the position, because
I've had it sort of play against itself (I was using SCID for analysis, and
pulled up the engine analysis with crafty) by making it's best move for each
side after about a min or so each time, and it routinely wins with black.

I would be interested to see a Deep Position evaluation of hte position from
Shredder or Junior or something Stronger than Crafty, but also I would be
interested in seeing games from a short engine match with this start position,
just to see if the evaluations can be trusted.  I don't really have the software
to pull this off on my own, but if it piques anyone's interest and they'd like
to post a follow-up, please do!
