It is always very dangerous to make statements like "no computer can
find the move here". In this particular position, I would guess that
a lot of programs find the right move quickly (though they will
probably not return a winning score). The amount of sacrificed material
is modest, and it is clear that black gets good attacking chances.
My own program plays Rxc3 at ply 4, after just a fraction of a second:
1 0.58 0.00 291 e6d7
2 0.25 0.01 922 e6d7 b1a1
