A 5-stoned handicap game (5d vs. 5k)


According to my own estimate, a handicap stone is worth about 7.5 points. So, against Klaashaas, assuming that his 5 kyu and my 5d do indicate our current true strength, I should win by approximately 40 points if we play an even game. Now, I am holding 5 black stones. So, I should, in theory, gain additionally 40 points. But the difference in two players' strength in Go is not a linear function of the scoring points. So, in summary, in this game, I consider a win of 65 points for black as a normal result. :)

Game 1 - Figure 2 (1-10)

White 10: According to the Go etiquette, white should play at A, not at 10.

Game 1 - Figure 3 (11-12)

White 12: 12 is a good move. For a handicap game, white may like to play a bit more loosely, leaving many local areas unsettled, so that there are more fighting opportunities. This move seems better than white A, black B, and white C.

Game 1 - Figure 4 (13-13)

Black 13: 13 serves double purposes: to gain territory and to threaten white group. Whenever a move serves at least two purposes, it is probably not a bad move.

Game 1 - Figure 5 (14-14)

White 14: White cannot afford to become too solid at this stage. A may be a better spot.

Game 1 - Figure 6 (15-16)

White 16: Still, 16 should be at A. Play in the most spacious area. Black already has the stone B. not too much fun for white. Had black had a stone at C, then 16 might have been OK. If white tries to attack black's group, white D, black E. It is safe.

Game 1 - Figure 7 (17-18)

White 18: White should play A, black B, and then white 18.

Game 1 - Figure 8 (19-21)

Black 21: For this situation, san/san at A is not too interesting, because it serves only ONE purpose -- gaining territory. It cannot attack the white group.

Game 1 - Figure 9 (22-31)

Black 31: For this first local encounter, white may be in trouble. A is injured, and the group B, C, D is floating. A baby dragon is born. Usually, if two babies are born TOGETHER, one is our own, the other is our opponent's, then it is OK. Or if the baby can be deserted, then it is OK. But in this situation, black's marked stones have formed a moyo, the white baby dragon must escape and grow.

Game 1 - Figure 10 (32-33)

Black 33: The exchange of A and B is necessary for both sides. <

Game 1 - Figure 11 (34-34)

White 34: My first intuition is to play at A if I were white. B is very aggressive.

Game 1 - Figure 12 (35-46)

White 46: 46 is a good move. Black was wishfully expecting white A, black B, and white C.

Game 1 - Figure 13 (47-51)

Black 51: Black group is safe even if white cuts at A. But to attack our opponent, we need to fortify ourselves first.

Game 1 - Figure 14 (52-52)

White 52: A is more urgent than 52. A serves double purposes, whereas 52 serves only one. After black's B, white cannot possibly attack this group any more. If black connects at C, then white still can leisurely play at 52.

Game 1 - Figure 15 (53-63)

Black 63: When attacking, always watch out our benefit. Move 63 intends to establish another moyo with the marked stones.

Game 1 - Figure 16 (64-67)

Black 67: 67 is a very vital point. A looks vicious, but perhaps is an overplay.

Game 1 - Figure 17 (68-81)

Black 81: Actually, overall, white has played quite well so far.

Game 1 - Figure 18 (82-93)

Black 93: Losing A and B stones is big here.

Game 1 - Figure 19 (94-100)

White 100: 100 should be reserved as a ko threat.

Game 1 - Figure 20 (101-111)

Black 111: T: Had white not made a blunder by giving the marked stones as a gift to black, and if white could live somewhere around D, white was not bad at all.

Game 1 - Figure 21 (112-112)

White 112: Bumping is usually a headache for the bumpee. :)

Game 1 - Figure 22 (113-120)

White 120: 120 should be at A. If black B, white C to play ko.

Game 1 - Figure 23 (121-121)

Black 121: After A is being captured, it is hard for white to live.

Game 1 - Figure 24 (122-129)

Black 129: Every move we play must bear some meanings. The exchange of A and 129 is strange.

Game 1 - Figure 25 (130-131)

Black 131: A is too deep.

Game 1 - Figure 26 (132-145)

Black 145: White resigns after black 145. In summary, A and B are good moves. Even though B did not work, but is an eye-making vital point. Black regrets the move at C. too slow. Because of that move, black almost made the game only marginally ahead.
