  simple 3 bar chain with no link fixed......
  that will give you- 3(3)-2x3=3
  since no link is fixed we wont subtract 1 from three

  3 links do not form a kinematic chain.
  
  they form an open chain, or if the chain is closed, it results in a superstructure

  that is impossible with just three links
  
  3 links cannot form a kinematic chain.
  
  either an open chain or a rigid chain can be formed.
