A bonus for attacks on loose pieces (or up-attacks) is quite standard. I introduced it in Rybka, it was duplicated in Ippolit, and of course is in Komodo. Since the Ippolit code is open-source, there is nothing secret about how this was done.

I was not aware by the term loose piece, and used "hanging piece" for undefended pieces (but not pawns) instead (cpw), even if not immediate exposed to capture. In English does the term "hanging piece" always imply it might be captured immediately? Or is it synonym to loose piece?

However, I understand loose pawns avoids the ambiguity with hanging pawns.
