2 mines left, and this is supposed to be No-guess.
However, it seems that there can be two answers to this -
(A) The top square of the top pair and the top square of the bottom pair, can both be mines.
(B) The bottom square of the top pair and the bottom square of the bottom pair, can both be mines.
But then this is not really guess free, is it ?
(Note - I did go with option (A), and it proved to be right. But my original question still stands).
What am I missing ?
The set I circled shows which square is safe, determining the mines for the other areas.
