Charles Matthews 3-dan introduces the game of Go

Handicaps and Grades

Who's afraid of a big bad dan player? Just as in the martial arts, Go has adopted a system of grades for players, though not indicated by belts of different colours. You can probably tell something about players' standing from the way they carry themselves in the club (come to think of it, neither fashion sense in the way of choice of accessories, nor good posture, is required to play Go). Confusingly enough, there are half-a-dozen Go grading systems for amateurs in operation worldwide; and the ever-larger number of online players encounter scales specific to each server. Let's concentrate first on the common features and purpose of the usual systems.

• The levels of a system are in theory the same distance apart - they represent equally-spaced rungs on a ladder of ability.
• This separation is supposed to represent one handicap stone. The appropriate number of stones handicap for players of different levels should be the difference in grades. (We'll return to the giving of handicaps in a minute).
• There is a break in the middle of the scale, representing the transition to dan (expert) status. The earlier grades have a decreasing number attached as you improve, then the more dan the stronger.

Grades have become built into the tournament circuit - in Europe the McMahon tournament, an adaptation of the Swiss to include players starting at a level representing their grade, is the common system. This leads serious players to place further weight on grades. However, the giving of grades isn't an end in itself (though Go players, not differing in this matter much from the rest of the human race, tend to excessive interest in the hierarchical side). Especially in a club like Dan's, handicaps make for interesting games between players of widely differing standards, where even (non-handicap) games will almost always be won by the stronger player if the grades aren't adjacent. Handicap games are teaching games, and the correct perspective on grades is that they should support teaching, not create minor celebrities.

Here is the start of a nine-stone handicap game, the classic teaching game between players of widely differing strengths. The board is set up with one black stone on each of the small "star" markings. Then White starts. Black's first plays are good, setting up a target for attack. White 5 is a typical handicap game play, and we can learn much from it. [Complete handicap games are covered in the "Big Pro Little Pro" series.]

Let's talk to KUMMERSUM about handicap Go - he's one player here who spends much of his time playing teaching games, giving large handicaps (six or more stones).

As KUMMERSUM tells it: "On the way to 1 dan from novice you have to improve about three times by a whole nine stone handicap. So it's not true that Black must inevitably crush White, with such a large start. Here at Dan's the initial grades are called kyu [pronounced like the letter Q], since we follow Japanese customs in most things. From 27 kyu, which is a beginner with just a little experience, to 18 kyu, a social player, may take a while, or be a matter of a couple of weeks if you are a games maven. From 18 kyu to 9 kyu brings you to club player level. At that point you are ready to surpass any current computer program. You probably drop the "I'm just a beginner" reaction at around 15 kyu, and start to look at some accessible Go literature. Working your way up from 9 kyu to 1 dan is the shank of the matter, and the best fun while it lasts. You can play almost anyone here on handicap and have a chance to win (not GOLD, though - he can give nine stones to a 2 kyu)."

"Handicap play may appear mysterious, until you have contact with an expert player. Three main points:"

• "Black's handicap stones don't control any territory, at the start. White can invade the corners at the 3-3 points as shown here. On the left - the correct general idea, with Black building a wall to construct a large box of territory by using the existing handicap stones (triangled). On the right is the orthodox sequence, where Black does even better because White is pushed down one line closer to the edge."
• "The game is long, so White waits patiently for small mistakes and closes the gap gradually. The nine stone handicap is worth around 100 points, but it is quite feasible for White to make these up in singles, as the cricketers say, at an average of one point per play."
• "Black has to learn the use of the handicap stones, for attack; but not try too hard to kill white stones. The usual way of talking about strategy for Black in handicap Go relies on the concept of influence, which is fundamental for all games of Go. It sums up all aspects not to do with immediately surrounding territory."

"Here White gains some advantage because Black is too keen to attack by cutting White. Black 1 and 3 take something in the centre but lose on the upper side - the handicap stone that controlled it has been roughed up. Black should have used it, not treated it as a freebie. In effect White tricked Black into premature aggression. Now White can contemplate invading at A quite soon. White may grind Black down with enough small gains of this sort. In any case White 2 here is a skilful dodging play."

"In contrast this way of playing by Black keeps the whole white formation under pressure, and looks towards building up the top left on a large scale. Imagine Black 1 added into the diagrams of the 3-3 invasion for the proper effect. No doubt White will try something confusing in that area, but Black really has nothing to fear."
