Djab: Thank you for the explanation
Indeed, the opponent could play elsewhere instead of E3 (after F1E1G1). I would then suggest to remove E3 from the sequence and display the message "Incorrect" just after G1, showing that the opponent is SENTE and can choose to reduce locally the territory (1 point) or play a bigger point elswhere
Just an idea
Djab: the correct answer is questionnable because it leads to a maximum of points (+1), but it ends GOTE compared to the combination : starting with F1 and ending with E4 in SENTE, I suggest to add a comment specifying SENTE or GOTE, or someting like this
caranthir: 1) it doesn't end in sente if in an actual game, the opponent doesn't play E3, but elsewhere, 2) the principal mode in these endgame problems is to maximise points locally, regardless of sente. When we don't know how the rest of the board looks, we can't assign value to sente.
