I was watching the Female Baduk League on Baduk TV one day and something very interesting happened.
After W made a mistake and got cut by B at the bottom, W was in grave danger as both groups were not alive.
Even though B’s corner is also not alive, B has many liberties and B also has strong influence on both the bottom right and the top right. This makes it a very difficult fight for W. The percentage for B also goes to almost 100%.
W managed to live the bottom group in the end, but the centre is in grave danger now.
Even though it’s W’s turn, B’s strong influence on the top right is waiting for W and there seems to be no way out.
W also doesn’t have enough liberties to go into a capturing race with B on the bottom left.
After struggling for a while, W still could not find a way out.
The cut on top was W’s last struggle.
Game was still good for black.
After W extends the cut stone to aim to capture the centre B group, B attaches the 2 stones.
This looks like a normal move, but from here onwards things suddenly started to go wrong.
It can be seen in the percentage bar as well.
Eventually, B managed to make a ko but W takes the ko first.
W didn’t answer B’s ko threat and took all the centre stones.
B didn’t have any chances after that.
This was the end result.
Who would’ve expected the game to turn out like this?
This was one of the biggest reversals I have ever watched.
Even the commentator also mentioned that he has never seen anything like this before.
A pity for B who had so many chances to win but went down this path eventually.
This shows that sometimes it’s better to keep on playing even when you know that you are losing by a lot.
It also explains why I still like to watch humans play even when AIs can easily beat top pros with handicap nowadays.

The cut starts at 3:01 and the reverse started at 3:19.
