Good weekend friends. Today's situation is about the choice of subsequent battles -
White first
The two sides fought early on the right, and the black chess piece with the triangle was just sharp in the three ways, and it was necessary to break the white chess piece to gain the initiative of the situation. How does white chess deal with it? Is it a direct war, or a detour?
A, b, c, d four points for your reference, to show your ideas!
Attached is the formation process of the situation map
Analysis: This game is based on the second game of the 71st Honinbo Challenge in Japan, with challenger Shinji Takao playing against the reigning Yuta Honinbo Iyama on May 23 and 24, 2016. In March of that year, Iyama Yuta defeated Itachi Tateshi in the Ten Dan Battle, unifying the seven crowns and achieving a great feat unprecedented in the past. This issue of the Battle of Honinfang was the first defensive battle after the seven crowns of Iyama in his hand, the first set of Takao Shinji won the white mid-set, and the second set of Ieyama counterattacked.
In the battle to the situation map, the white Iyama made in-depth calculations in the face of Takao's initiative to fight, and came up with the strongest means of counterattack. Let's analyze a few selection points one by one.
Figure 1 point a
White 1 long, direct combat posture.
Black 2 flies out, white 3, 5 are commonly used tendons.
Black chess simply eats one son, when the white 9 is long, the black 10 breaks the three sons of the white chess, and the harvest in the field under the right is huge.
White 11 roughly needs to be broken, black 12 jumps up, and the external potential of white chess is limited, and this change of white chess is not sufficient.
Figure II Point c
White 1 hit into the turn, flexible thinking.
Black chess direct cover pressure combat can also be, choose black 2 wrench to require conversion is also a good idea.
To the white 11 stereotype is roughly like this, after the black chess piece controls the midfield, the black 12 attacks the right white chess.
This figure white chess wins first, but the black chess also achieves the purpose of entering, and then both sides are not easy to master, which is not in line with Jingshan's style of pursuing initiative.
Figure 3 point d
White 1 flying pressure below, intending to sound east and west, has a master style.
Black chess can not let the white chess borrow strength, black 2 jumps out, white 3, 5 roughly take care of the right two sons first.
Black 6 and 8 will brazenly break through, it will be a scuffle, and it feels like the burden of white chess is slightly heavier.
In actual combat, Yuta Iyama chose to fight directly after in-depth calculations, but the method was more rigorous——
Figure 4 Point b (actual combat)
White 1 fly, nice hand.
Black 2 and 4 hope to go into a situation similar to Figure 1, but white 5 stickers are compact and good moves.
Black 10 is calm, black 12 can be contacted, but white 15 is eating, and the external situation is very strong. Next --
Figure 5 (Actual Combat Continued)
Black 1 break, white 2 pointed a good order.
White 4 long, 6 wrench, discarded.
Black 7 is to get the first hand of 9 breaks, and has to endure the pain to eat.
Although the black 13 is eating and living in the lower right, the field is very large, but the white chess is monstrous, or the first hand.
White 14 kept punching into the left side, then forcibly robbed, and finally used the robbery material in the lower right corner to blow up the black chess.
With his strong strength and compact moves, Yuta Iyama defeated Takao Shinji in 230 hands, equalized, and went down three more cities in the ensuing competition to defeat Takao's challenge 4-1 and successfully defend the throne of Honinbo.
With the global chess score for everyone to enjoy:
