Front post double crochet

Front post double crochet (FPdc): 
NOTE: Post stitches are worked under the top loops of a stitch, and around its post -- the vertical part of the stitch.
(1) Yarn over, insert hook from front to back to front around the post of designated stitch, and yarn over.
(2) Pull loop around the post.  (Three loops on hook.) Yarn over and pull through two loops, yarn over again and pull through remaining two loops.
