Game 1
The hard cap next to that back wall was a nice position to hold to keep those road threats going and forcing the black capstone to keep vacuuming up pieces for a few rounds.
Game 2
I felt very clever about my wall-smashing road at the end of this one, until post-game, Sky pointed out I had a solid Tinue halfway through the game I flat out ignored multiple times, hyper-focused on the horizontal threat. Reviewing the game with ptn.ninja it seems impossible to me that I would miss it, yet there it is.
