History in the making: first Lee Sedol vs. AlphaGo match game

I was up to 1am this morning watching the game live. I became interested in AI in the 1970s and the game of Go was considered to be a benchmark for AI systems. I wrote a commercial Go playing program for the Apple II that did not play a very good game by human standards but did play legally and understood some common patterns. At about the same time I was fortunate enough to get to play both the woman's world Go champion and the national champion of South Korea in exhibition games.

I am a Go enthusiast!

The game played last night was a real fight in three areas of the board and in Go local fights affect the global position. AlphaGo played really well and world champion Lee Sedol resigned near the end of the game.


  1. If the game had been played to the end, how many stones would alphago have won by?

  2. I think that Lee Sodol was ahead by about 2 or 3 points on the board, but AlphaGo, playing white so having the disadvantage of playing second, gets a 7 1/2 point Komi. So, I would guess that AlphaGo would have won by (perhaps) 3 or 4 points.

  3. I'm going to have to give it a go myself, Hate t admit I'd never heard of it.
