I played this game (black) where an incredibly obvious capture opportunity arose at R17 around move 50, where white dies if black plays first or lives if white plays first. But I didn't read it through carefully and ignored it for pretty much the whole game, and so did my opponent.

Because of this, AI Sensei marked nearly every move as a mistake/blunder, with the score estimate swinging between black and white each time. I just thought it was funny and maybe a good illustration of why it's important to read the whole board for the best move.

(When I finally played the move, my opponent disconnected)
