;W[rf]
;B[re]
;W[qh]
;B[kr]
;W[ln]LB[jp:A][lq:B]C[This kind of a light shape move struck me as particularly human-like. White is defending against the threats of black A and B while building influence in the centre.]

;B[qb]
;W[fe]C[By this cut, the centre is becoming increasingly white.

If it was Zen or CrazyStone playing white, from now on it would probably start playing cosmic style and aim to kill black's reduction attempt.

However...]

Black accomplished what he aimed for, but at the cost of losing sente and giving white thicker shape with A, B and C. A particularly is surprisingly big, because D is no longer black's privilege for endgame. Thus, black cost some territory in reducing white's moyo.]
;W[oo]
;B[np]LB[nl:C][nn:A][po:B]C[This move appeared a mistake for black; white now gets to exchange A-B in sente, which creates white C for building more influence in the centre.]

Black has a lead of 54 to 41 (not counting komi), but white has a considerable amount of centre influence that is not taken into account. If white finds ten additional points of territory in the centre, the game will already be hard for black; and and it certainly seems possible to create ten points around A.

;W[ng]LB[kl:B][nm:A]TR[oi][pi][oj][pj][ok][pk]C[Black erased a good 6 points of potential white territory while letting white get increasingly more thick in the centre. Also, A is becoming white's privilege, meaning that the ten points around B will materialise relatively effortlessly.]

At the same time, white built thicker shape with â–³ and retained a peep at B, which is efficient at building more territory in the centre: thus, black can't be said to have gotten sente, either.

PW[AlphaGo]PB[Fan Hui]BR[2p]DT[2015-10-09]EV[AlphaGo vs Fan Hui five game match]RO[Game 5]PC[London, England]WT[Computer]BT[Human]SO[https://gogameguru.com/]AN[An Younggil 8p]C[This is a commentary of the final game of the five game match between Fan Hui 2p and Google DeepMind's AlphaGo.

News of AlphaGo's 5-0 victory over Fan shocked the Go community and made mainstream news headlines around the world.

The game was played on October 9, 2015, but the startling performance of AlphaGo wasn't revealed until a paper detailing the feat was published in the science journal Nature, on January 27, 2016. This means we have only recently heard about the games and had a chance to analyze them.

## Why Go?

Go has long been a significant challenge to artificial intelligence (AI) researchers, because the large number of possible Go games make it infeasible for computers to perform well using brute force alone. This has meant that the best human players have until now remained out of reach of the best computer players, despite decades of research into AI and advances in computing power.

## Fan Hui

Fan Hui is a professional with the Chinese Go Association and has been living in France, where he has taught and promoted Go since the early 2000s. He was born in 1981 and became a pro in 1996.

Google DeepMind contacted Fan to arrange the match and he played against AlphaGo in London, under the supervision of Toby Manning from the British Go Association. Ten games were played in total; five official games and five unofficial games. Fan chose a time limit of 1 hour main time and 3 x 30 seconds byo-yomi each for the official games. He won two unofficial games against AlphaGo (30 seconds per move), but lost all the official games.

The first game of the match was quite leisurely and territorial. After Fan lost that game by 2.5 points, he thought that perhaps AlphaGo didn't like to fight, so he played more aggressively in the games that followed. Unfortunately for Fan this game plan didn't pay off.

## Alpha Go

AlphaGo is a Go AI developed by DeepMind -- a British AI research company which was acquired by Google in 2014. They are undertaking a self-described "Apollo Program for AI," in a project involving more than 100 scientists.

### Neural Networks

The backbone AlphaGo's strength lies in its successful application of neural networks to Go. In this context a 'neural network' is a technology for processing information and forming connections in a way that is modeled on the neural connections in the human brain.

The goal of this technology is to enable computers to learn in a way that is more general and human like. DeepMind aims to develop a general learning algorithm which can be applied to many problems instead of a pre-programmed AI which is only capable of doing one thing (e.g. playing Go or chess). The chess computer Deep Blue, which defeated chess grandmaster Garry Kasparov in 1997, is an example of the latter (pre-programmed) AI.

It appears that AlphaGo, being a stepping stone along this path, is currently a little bit of a hybrid of the two approaches. The more general purpose neural network has been 'trained' by giving it access to a huge number of Go games between skilled humans. The 'knowledge' it has acquired throughout this process has been reinforced by allowing it to play an enormous number of games against itself and evaluate them using some serious hardware.

### Monte Carlo

However, its strength is further boosted by the use of Monte Carlo Tree Search (MCTS) -- a technology which has already been applied to Go for about a decade and has led to computer Go programs making great strides against amateur level players.

MCTS applies a statistical approach to finding good moves. It is a search algorithm where the computer simulates many possible games and, after seeing the result of each random game, aggregates all the results to calculate a probability of success for a selection of next moves. If this sounds counter-intuitive, that's because it is!

MCTS does not require a great deal of domain specific knowledge (knowledge of Go provided by a human creator) to perform well, but a programmer still has to configure and tune this approach for the game in question. One of the problems AI researchers have faced with Go is that it's difficult to evaluate whether a position is good or bad.

For example, you can't assign scores to pieces like you can with chess, because the pieces all look the same. MCTS has, until now, evaluated positions by simulating all the way to the end of the game, counting the score, and then aggregating the results of many simulations.

### Putting It All Together

AlphaGo changes the way MCTS is applied by using a neural network to evaluate whether a position is good or bad. DeepMind has actually trained two neural networks as part of AlphaGo. The first, called the 'policy network', chooses promising looking moves for deeper analysis -- similar to what humans do when they rely on instinct.

The second, called the 'value network', specializes in positional judgment. The value network allows AlphaGo to evaluate a position without playing each simulation all the way to the end of the game. This makes MCTS work more efficiently than it did in the previous generation of Go AIs.

White was winning by about 10 points on the board, and Black couldn't find a way to catch up.

Unbelievably, AlphaGo defeated Fan Hui 2p again, and won the official five game match with a flawless 5-0 score.

The opening up to White 34 was even, but Black 35 (A) was questionable and White was slightly ahead up to 52 (B).

Black 57 and 65 (C and D) were mistakes, and White took the lead.

White 70 and 74 (E and F) were wrong, but Black 75 (G) missed a great chance to take advantage of them.

White 80 (H) was an overplay, but Black 93 (I) was premature and can be regarded as the losing move.

White established a clear lead with 94 (J), and didn't give Black any chances to catch up afterwards.

White's play in the second half of the game was excellent, and I couldn't find any serious mistakes from White.

AlphaGo's style seems to be slightly territorial, but well balanced. It's good at haengma and tesuji, but its play is not yet perfect.

As we can see, it made several questionable moves and mistakes, but its play in the second half of the game was much more accurate and refined than the in the first.

AlphaGo's games throughout this match were very impressive, and I never expected that a computer Go program could play such strong and smooth moves.

It's so surprising and shocking, and I look forward to watching the match between Lee Sedol 9p and AlphaGo in March 2016.

When AlphaGo faces Lee, we will be able to see more clearly just how strong it is, and how much it has improved since October 2015 (when this game was played).
