Hello!

Can you help me?

I am looking for books (or pdf or whatever) for dan players, of endgame, concrete situations not the middle gamish kind, preferably with solution. Also looking for dan level tsumego but only WITH solution.

Thank you for your help!

I don't know how easy they are to get anymore, but the endgame book in this series is high level:

권갑용바둑도장시리즈

I recommand train like a pro, you have everything inside. Opening, tesuji, tsumego and endgame problems.
The first book is not too hard but the second book is hard hahaha.
