This is guess-free, and 14 mines left, all under those uncovered squares.
Any thoughts on how to proceed ?
EDIT - never mind. Tried brute force with the hope that the path I choose would be the right one - and lost.
But there’s always a next time mine, lol.
And it was indeed heartening to see the Minesweeper community in Lemmy is not dead.
I was more going for the right 3 having the two rightmost squares be free of mines. Because the 4 has five squares surrounding it and four of those five squares are also in contact with the 3 on the right, no matter how the mines are arranged all three mines would be to the left or center of the 3. This leaves the two right squares unable to be mined.
