Here is an example of a <BD>technical</BD> win. Notice that the player denoted as <BD><COL=RED>Red<NM> (Player B) has been able to complete its piece formation, except for the remaining cell occupied by the <BD><COL=BLUE>Blue<NM> piece. Therefore trapping opponents' pieces within your destination area is a winning strategy.
On the other hand, leaving pieces behind is not a good strategy for success.
