Quoting Eric Backus:

I've been enjoying your latest release (particularly the new endgame problems), and I see

that these changes made it in there. Thanks!

Sorry for the late response to your corrections of the bundled problems. I'v included most of them in the V1.2 release, and below are explainations of those not included in the new release:

Basics/11 Net/27: Move 1 at the 5-7 point also works?
Yes, it works, however it's not the best solution. After white responds at 5-8, Black have to play another move to secure the capturing of white. And obviously black at 5-7 is much less valuable than white at 5-8.

Basics/12 Oiotoshi/13: Moves 1 and 2 can be swapped
Yes, it works, however the black will lose one ko threat

Basics/12 Oiotoshi/18: Moves 1 and 2 can be swapped
the same reason as above, it's not the best solution.

Basics/14 Squeeze/2: Moves 2 and 3 c an be swapped, last move can also be at 2-4
Yes move 2 and 3 can be swapped, I've updated it. However, although last move at 2-4 works, it's not best solution.

Basics/19 Seki/17: Moves 1 and 2 can be swapped
Incorrect, because white no need to save two stones, just play at 2-2

Basics/20 Life and Death/75: Should allow white at 3-2 point (snapback) (Or not because it leaves a ko threat?)
Yes, it’s not the best solution

Basics/22 Final Review/24: Move 2 can also be at the 5-4 point(Move 3 at 6-5 point, then either snapback of 3 stones, or squeeze)
Yes, it works, but not the best solution.

By the way, I saw your review on Appstore, thanks you!
