Naturally I'm not going to try here to give a compressed version of half a century of Go opening theory. Theories for Black and White are the weapons, may not yet have reached its conclusion. The process, resembling an 'arms race' in which opening The statistics have always pointed to an advantage for Black, the first player, with the lower values of komi and professional players have over time adapted to playing with komi by using more aggressive strategies when starting. At that point komi was usuallyĤ.5 points the higher value 5.5 came in a generation ago, and 6.5 was introduced in Japan only in 2002. The short answer in this case is that in Japan, komi has been the general system since about 50 years ago, as newspapers sponsored more tournaments and long, specially-arranged, matches between top players died out. Most of the interesting and significant questions about Go have answers that come in terms of its rich and varied history in the countries of East Asia. Started but that's not a scenario with much connection to the real world.) What lies behind this number? How could one come up with such an estimate of the advantage of starting? Can one even prove mathematically that the first player has any advantage? (The answer to that one is that "passing" is allowed, so that if there were any reason to believe the opposite the game would never get properly Perhaps if you haven't played Go this sounds vague and unsatisfactory. The half-integer value prevents draws, which is a big plus in itself: we know that the correct value will be an integer, so in a sense what this tells you is that the belief is "it's These extra points, called komi in Japanese, or dum if you're in Korea which is a hotbed of the game, are now set at a level of 6.5. Who starts, White is awarded a certain number of points to add to the final score. Tournaments everywhere use the principle of compensating the second player. Of course, we are a very long way from knowing so much about Go, except when it is played on tiny boards (up to about 5x5 in size, where 19x19 is the regulation grid). Put that way, it doesn't sound very sensible: the game should always be a draw, and so hardly worth playing competitively. Question, how much is it worth to play first? With best play on both sides, the winning margin might be, say, 8 points for the player who starts and therefore we should compensate the second player by giving her or him an extra 8 points of score. Go is a game that is scored at the end, which means that in principle we could get a definite answer to the The game of Go has been introduced in two previous articles on this site (' Behind the Rules ' and ' Sufficient but not Necessary '). Some mathematics of parity lies behind that, in a well-concealed way. The system for Go is to add to the second player's score a number of points, in compensation for the first player's starting advantage. Naturally this depends on thereīeing opening plays which are indifferent: only about half as useful as the best ones. The player who starts must give the second player the choice of changing sides after the first move. In Hex, which is known to be a first-player win but for which the winning strategy isn't understood, the so-called 'pie method' is applied to give interesting games. Here are some links to the games mentioned In the mancala game Oware, a proof has been announced that best play leads to a draw. In mathematically analysed games, such as Nim or Gomoku, first play should be decisive. In chess, starting is a major boost for an expert, but in shogi (Japanese chess) that isn't true. Games for two players differ widely according to the received wisdom on the advantage of first play. Further strategy is covered by Two eyes and Seki in Go.
