Go up one level in this thread

This is a pretty interesting position.  As it happens, Tinker finds Rxc4 in
about 1 second at ply 7, BUT only with a special version of the evaluation
function that I have been testing (with little success so far) that only uses
material and piece square values.  It sticks with this move with a slowly rising
score until at least ply 12 (+0.44).  Funny thing is that Gerbil (also material
and piece square only eval version) does not like Rxc4, so there must be
something else going on here with extensions or something else search-related.
