Puzzle #73: A Puzzle from Both Sides

Hello all!

Tonight's puzzle is from a board state forwarded to me by SultanPepper. Thanks, Sultan!

Part I

The first part of the puzzle is a Tinue puzzle. For the purpose of this puzzle, Tinue is defined as a board state in which no matter what the opposing player does during their turn (Black, in this instance), a road win will be awarded to the other player (White) on their next turn. If you are familiar with Chess, Tinue is very similar to Checkmate.

The Tinue that I found ends the game in 7 turns, but, there may be other options that I haven't considered; see what you can find!

Please form your answer with PTN or a link to your solution via ptn.ninja. And, remember to add the r/Tak spoiler tag to your solution so as not to ruin it for others. To do this, put your answer in brackets and follow with (/spoiler). Ex:  [26. a3- Sa3](/spoiler).





Part II

The second part rewinds this puzzle 1 move (1/2 a turn). Now, viewing things from the other side, what can Black do to avoid Tinue? I only found 1 successful move, but, as above, see what you can find!

I hope everyone enjoys this one; it's quite an interesting board state.
