Yeah, forgot about the pawn.

Checking it I know it with bPb5->c5, but that version is quite some worse than yours...

(#16)

This version is not even legal - 15 black pawn captures are needed and white has 2 units on board.

I only count 13?

Nevertheless your version is better.

Right - 13.

Hmm. I would think they'd try to move Rb3 to c2 if they have spare captures to play with. Composers tend to frown on heavy pieces that exist just to get captured. Much better to capture a pawn instead.

In 'my' version, I obviously don't have that luxury.

What is interesting about that position is that if white plays 1. h4, he only draws, but after 1.h3 he wins.
