@gino betti omg I'm so sorry if this happened I will change it now!!

For the record, it's easy to trick this DDK with multiple ladders as well. ;-)

This position was checked by Leela zero, fun that it is considering whole bunch of moves beside only this one)

@@petribalanceisnice Without a doubt. I agree.

Haha no.. just a quote of what you said. ;) What a great game to end a career! I love how Lee Sedol never shies away from complications, even when facing a superhuman opponent.

I think you're correct insomuch as calling it a "bug" is a little misleading. It's more like Lee Sedol "played a specific kind of variation that lead to the AI overlooking something". It's actually fascinating the Lee Sedol has managed to do this twice. I wonder if something about his playing style / tesujis he looks for somehow leads to situations that confuse the AI. Or, it's just a coincidence :) On "'I've fed some of my games through Leela Zero and even I have seen cases where it just couldn't read out a simple ladder" -- that probably has more to do with your computing power. Leela (and most AI) have trouble reading ladders if the computer has insufficient processing power. If you let your computer run variation for long enough, Leela will eventually realize it's a ladder. I think that kind of error is very different from the exploit Lee Sedol found in this game. Handol was probably powered with a super computer. Handol simply couldn't foresee the net, irrespective of how many variations it read out.

Yes exactly!

Now

Yes on hangamebaduk but not a version against Leesedol
