Ps3 And Huawei Dongle

Being a victim of your own tesuji

say that in reality, the computing power does not depend on the status of each, and it is true. What happens is that the stronger players are better able to rule out moves that you know are wrong, allowing them to reduce potential arc at each position, allowing them to increase the depth of calculation. In contrast, the weaker players are forced to calculate a potential arc wider and therefore more difficult to calculate. So, your computing power has much to do with how many sequences have already memorized precomputed so to speak. In these "sequences" and we call tesujis precomputed in Japanese, Korean haengma (행마), and are extremely practical. But this series of little tricks have a small problem. Often, we got used to recognize the positions in which they can apply tesujis but sometimes we overlook the fact that certain sequence should not work for the enemy if it works because of a stone that we are not taking into account, which usually lead to disaster. I will give you an example:

5 th round of the Barcelona tournament this year. I'm white. My opponent, a French 2d which had already played earlier in Paris. White has just played just 1 to reduce the influence of black when it strikes with 2.

tesuji standard starts to cut the target area, without paying much attention to the marked stone, which seems to have no influence on the sequence.

Jumping in A, black bears in mind this sequence, which is clearly favorable for black. Because white can not cut into 1, as evidenced by this sequence, the situation seems to favor black, but ...

Black has not taken into account the effect that the marked white stone is in the sequence, and is surprised by the movement of white 1. Up to 5, black is captured. Yes, I know, the fight seems complicated. I invite you to try for yourself. Sure you will reach the same conclusion we reached my opponent and me.
I leave the whole game if you want to see. Obviously, it is commented.

The Significan Of #12 At Alabama Football

Tournament Barcelona 2010


On 20 and 21 February (and has been a while, I know) is played most heavily Barcelona Tournament to date. Nothing more, nothing less than 146 participants, among which are household names such as Cornel Burza, Hwang In-Seaong, Ondrej Silt and Cristian Pop The winner was Du Qing, a player Chinese living in the UK, but, above all, to congratulate the organization. What it means to organize a tournament for 80 or 90 people and a tournament of 146 can only be described as hell. I leave the link to the blog of the tournament, if you want to take a look: http://bcn2010go.blogspot.com/



Well, Chapter staff, say I'm quite pleased. 3 wins against players my level or lower (3d-2d) for 2 losses against stronger players (4d). My problem with the rooms Danish start worrying, but this time I found that the parties were perfectly matched and could have won. As I said, I'm satisfied. Additionally, I was second best English tournament, behind only Oscar, which puts me in a favorable position to enter FdCE this year. See what happens.



For if you are interested, photos of the tournament (like almost all the photos that hang on this blog) are Isa. If you want to see more, you have here:

Finally, I leave my first game of the tournament, against Javier Fernandez (black). Interestingly, I play pretty comfortable against him, despite being undoubtedly a hard nut to crack. Who knows, maybe it's me ... I play bad happens to me with other players ...
