9X9 Can you solve my Puzzle (if there is a solution)?

I recently played this game on OGS and lost. After a few moves, I could not find any way to win as white. I am wondering if my analysis was correct.
Can anyone find a way for white to win the game from move 13 w to play to the end?
Thanks everyone!

I think there's still too much play left in the game at move 13. It does look better for black, but it looks like it could get pretty complicated:

Better for Black I think

Thank you for the replies. I take it by the lack of other suggestions that white could not win.
I appreciate the feedback.

I don't think I could win at move 13 anyway as White - I think the mistake may have come on moves 6 and 8 - my gut feeling is, letting Black build up that size of a side, something that threatens to live on the other side of the board may be required at that point.

I agree. 6 now looks too deep. The intent was to split black, but I didn't read it through well. Thanks for the feedback.
