Puzzle 8  (2)

It's White's turn. Apparently he's in trouble: he has only 2 pieces left to play and quite a few lines on the board are blocked (i.e. all spots occupied), which makes play more difficult. He must recycle pieces. Will he be able to create a row of 4? Or is there even something better to do? What would be his best move?

Possibility 1: a1-c2
Possibility 2: a3-c5
Possibility 3: b6-d6
Possibility 4: f1-f4
Possibility 5: i3-d7
