How many loose pieces can you find in 60 seconds ?

I got 43 after lots of attempts.

20 after 3 tries

Great challenjge!
I think it may improve you tactical vision

But, if any piece have N attackers and N defenders - it is same with unprotected too.
0 attackers and 0 defenders, 1 attacker and 1 deffender, 2 attackers and 2 defenders etc...
