Why did white resign?

In this game, https://online-go.com/game/20333621, I was playing the AI who’s resignation (move 63) took me by complete surprise. Can someone please explain or shed some light on why whites position was that bad?

Thank you

Black already leads by many points.

Black controls about half of the board, while white’s territory is about a quarter. (Without counting)

In case you wonder: black A6 or C6 kills the white group on the left.


Wow! Looks like a wormhole move! You play on the left and kill the right!
Just joking! :smiley:


You’re right of course, just looked to me as though there was a lot of potential territory in the middle for white.
