Last move? Black to move

13829 - Werner Keym
Dedicated to Thomas Brand' introduction

Construct an IC with as many pieces as possible on a straight line. The 
piece that's farthest away from its homesquare is on a white square.

Original text:
Konstruiere ein Illegal Cluster mit möglichst vielen Steinen auf einer 
Geraden. Der von seinem Ursprungsfeld am weitesten entfernte Stein steht 
auf weißem Feld.
