It seems like if your primitive operation is "break bar in two" you
need exactly n-1 breaks to get n squares, no matter what choice you
make for where to break along the chocolate grid.  This is a simple
consequence of the fact that each break increases the number of pieces
by one.

If you're allowed to hold multiple pieces in your hand when you do the
break it's different.  Then you need a model of how the hands hold the
chocolate.  I think there is a problem when the breaks get
complicated, as if you have to hold the pieces for too long while
setting up the break, some of the chocolate will melt onto your
