Poleweapon and shifting

[DHood64]

(sorry hard to draw with text). Image this is the situation, right before movement phase..

space a | player 1 | space b
---------+---------+---------
space c | player 2 | space d
---------+---------+---------
space e | space f | Player 3
---------+---------+---------
space g | space g | 1 hex monster with Pikeaxe

if the monster moves to space f during movement phase...

is that considered a 1 space charge? aka does the monster get the "polearm strikes first" since charge on player 2?
what the polearm vs Player 1 and striking first?

(its understood no extra damage dice)
