TwT: The original text is: Black has a tesuji by which he can either rescue his isolated stonein the corner orprevent White from linking up his four at the center top. To alter the text would help?
caranthir: I think the hint "separate" suffices, based on the rationale that even Katago's local continuation is to separate *if* it were first to play J10. I'll accept the line starting with J11 (a few blue moves down the line) with a note at the end "AI sequence, but does not separate opponent groups". If you're unhappy with that, feel free (y'all) to revert to the original or change the problem in some other way. ------- The reason why the problem is kind of messy is that the separation, while pretty good, is gote. The Katago top sequence is sente and there are even empty corners to grab still. Not that you gentlemen didn't already know that, but I'm just writing this as a reminder to myself and anyone who suffers to read my comment.
TomaLexi: Plenty of moves that work here, J11 to threaten to go into/reduce the corner. Direct descent at H13 or even just connect at H11. The current correct move is the worst out of all of them according to AI.
caranthir: [Ivan Detkov:
Yes, it is a total mess.]
-------
With low playouts, the correct move is blue. With some time, J11 comes out better, but the "correct" move is not that much worse (under one point). I could change the hint as per TwT:s proposal above to make it clearer. J11 could be accepted with a note "AI move".
