PASSEDP--Passed Pawn Creation. We often try to create a passed pawn in order to either promote the pawn or tie up the enemy when he tries to prevent you from promoting. There are several ways of doing this.
1)exchange
2)capture

1) PGRABLOOSIE--Loose Pawn which has no means of support, visible or invisible.
2) PGRABPIN--Protected Pawn which is nonetheless grabable due to a pin.

PP--Pawn Push: There are several reasons to push pawns.
1) PATT--To attack a piece or pawn. 2) PF--Pawn Fork
3) CREATEPP--Create a passed Pawn PROTECTIVE PPP--A pawn push to protect a piece or pawn.
PROTECTIVE PPM--A pawn push to protect against mate 4) PPP--Passed Pawn Push PREMOV--Pawn Removal:

2) ENPREMOV--Removal of enemy's pawn. a) ENPREMOVCAP--Removal by capture.
