TwT: @posetcay: If duplicates are merged only the text of MAIN is kept, the other will be deleted. When I merged duplicates I copied relevant comments that appear as my comment.
If you want I can mail you a backup of the deleted false tree.
posetcay: Do comments in other collections get deleted when a merge happens? There was a lot of valuable discussion about this position in other collections I believe, It would a shame if they just disappeared.
kovarex: Hello, I can't take a look at the broken variation anymore, as the history is now lost, but there really isn't a stone in the book, and looking at the current position, it seems like it isn't really needed, but maybe some refutation exists that I missed? I don't know. Anyway the solution in the book seems to be the same as here.
kovarex: I took a look into the book more, and right, the answer of B19 to A18 isn't considered in the solutions, only B17. It is the same otherwise. This suggest the book problem was ineed broken, as this answer wasn't considered. It isn't the first time we found an error, which is good, as this collection will be better than the original book :) Thx for fixing it when i was away.
TwT: [History] 1000 Weiqi problems - 2nd half 60 (without a stone @N17 was classified "broken" by Master Ivan Detkov. Master caranthir suggested: "So one option would be to just replace and merge this with Igo Hatsuyoron #10 and call it a day. But before we do anything, can we call upon @kovarex to double-check if the starting position here is indeed the same as in your book?" I merge-solved the issue. Anybody in need of the "lost" broken solution of 1000 Weiqi problems - 2nd half 60, may feel free to ask me.
