and last game, leading to a final score of 4–1. Each of the five games played has been widely followed and analyzed. This marked the first time a computer had competed, much less won, at the highest level of the game, and each game gained worldwide coverage. Games 1 and 2: AlphaGo's first game victory was seen as a possible reflection on the stress facing Lee Sedol, and possible resulting mistakes he might have made. Lee Sedol had attempted to test its skill in the opening game. After AlphaGo's second victory, for which Lee played far more of a cautious "waiting" game, intended to give away few weaknesses, Lee was reported as saying "Yesterday I was surprised but today it's more than that, I am quite speechless. Today I feel like AlphaGo played a nearly perfect game. Game 3: After the second game, there were still strong doubts among players whether AlphaGo was truly a strong player in the sense that a human might be. The third game was described as removing that doubt; with analysts commenting that "AlphaGo won so convincingly as to remove all doubt about its strength from the minds of experienced players. In fact, it played so well that it was almost scary ... In forcing AlphaGo to withstand a very severe, one-sided attack, Lee revealed its hitherto undetected power. ... Lee wasn’t gaining enough profit from his attack. ... One of the greatest virtuosos of the middle game had just been upstaged in black and white clarity." Game 4: Lee played a type of extreme play, an amashi strategy, in response to AlphaGo's apparent preference for Souba Go (attempting to win by many small gains when the opportunity arises), taking territory at the perimeter rather than the center. By doing so his apparent aim was to force an "all or nothing" style of situation—a possible weakness for an opponent strong at negotiation types of play, and one which might make AlphaGo's capability of deciding slim advantages largely irrelevant. This strategy unfolded around 47, but by around 69 to 76 commentators had begun to feel Lee's play was a lost cause. However a play at White 78 described as "a brilliant tesuji", and by Gu Li 9dan as "the hand of God" and completely unforeseen by him, led to Lee's first victory when AlphaGo made several bad moves in response and finally proved unable to recover
