This is a problem from an Android Tsumego app... My solution started like this... But the app responded like this, saying I was wrong... But I think that this should now happen... Where have I gone wrong? Aside: Why is there no "Problems" subforum and what is up with "Beginners" and "Amateurs" - after a slight holiday from L19, these things do strike you when you return. |

I thought so. I always prefer to play on the outside of a group like this, even if a placement or throw-in does work. EDIT: I can't seem to find a problem-feedback option in the app. Does the dev. read L19? |

It might be preferable to play 3 @ R17. Playing from the outside is always better than doing so from the inside, if both options do the job. |

Agree, the placement was my first try, then I read the proposed solution. I'm usually guilty of finding a solution (or a wat to proceed) and sticking to it without looking further. An area I try to improve

The difference was probably that Charlie focused on a different critical point in that shape. The solutions seem equivalent to me really, White can take sente and leave a ko threat for themselves behind in either case. |

What did the app give as the correct solution? There is no lack of amateur tsumego problems with more than one solution. |

The app provides this solution: This would be why I prefer apps that play out White's moves here, rather than just marking something as incorrect just because your move for White isn't the programs. Of course, apps with more than one variation for White in response to the same starting move are better, just to make sure you actually read things out. Edit: I mean, if Charlie was presented with  then  above by the program he'd have no problem finding  and  and he wouldn't be finding the problem marked wrong for him. He might disagree with but that's where you just confirm again that your also doesn't change the result. In this case there's only ever one eye in there after regardless of what white does so it's much of a muchness. In sdk/strong ddk problems there's often alternative answers but usually the book answer is better in terms of endgame, sente or ko threats or whatever.
