There is a slight error: 1/2-1/2 should not be interpreted as part of move 44. Rather, it is the game result. 1-0 means a win for White, 0-1 a win for Black, and 1/2-1/2 a draw.

Note that every time it appears, the piece that moved there is either captured, or (in move 37) the king moves. I note also, for example in move 37, the rook moved to a6, with the opposing king at d6.

Judging from the sequence of moves, the "+" probably stands for check.

If only it was so simple...

Even leaving apart variations or clock info, let me mention promotions:

37. c8=Q+

(promotion to queen with check) or

42. exf8=Q#

(pawn e7 captureson f8, promotes to queen and mates)

off topic..

With regard to your regex's, I would normally try and write @"\[.*\]" as @"\[[^\]]*\]". With the idea that it matches anything that isn't a closing bracket.
