Comment[I played balck as yfh2

I lost this game by few points, while I thought after the fuseki that I had an advantage.

Two things :

Either I misread the board and the position advantage I read was inaccurate. In that case, question is : why did I misread ?

Or, my opponent succeeded in screwing my position. Question then is : how ?

I have the impression that appart from a couple of small mistakes that did cost me a few points, there was no patent blunder in the middle game.

However, I have the impression that in the end game, I lost sente, and therefore many small points.   Overall questions are :  1) Is this statement correct ?
2) If yes, where should I have prevented this
3) If not, where is my blindness ?

Thanks for your comments.]

Comment[This move is too slow because white can invade black upper right territory in "A" and destroy black territory. Moreover, with this move, you cannot really attack the two white stones : they can live with "B" or escape to the center.
Better to play completely elswhere : for exemple at "C".]

Comment[Now if you want to make real territory in the upper right side, you have to add an other move in "A", and so white can developp himself rappidly.]

Comment[You cannot extend so much now after the exchange of B4 for C3 because if white invades in A you are divided in two groups and you are entering in a very difficult battle (for black).
You shoul have play at "B"]

Comment[You see, like this, you didn t make any territory and white has reinforced his group.
Moreover it seems to be quite sente for white because capturing the black stone is big because it makes the black group weaker.]

Comment[W : 32
8 bottom left
8 right
7 top
5 corner

B : 31
11 bottom right
5 top right
10 left
5 top

For black, I did not count the miai of Q18 or M3, that can add 5 to 10 more

Besides, Black has more influence on the center.


Anything wrong in this ?

My counts are :

W : 40
12 bottom left
12 right
8 top
8 corner

B : 35
15 bottom right
5 top right
10 left        here it is not yet decided because white can easely invade at "A"
5 top

In real territory white is leading but it is right that he hasnt the control of the center;
Moreover black can make more territory in the bottom and in the center. I think black should now protect at "B" or "C". But white can attack the upper black group so right now, it is difficult to say who is really leading.]

Comment[Here again, It lloks like B is ahead by more or less 5 points to me. (counting next W moves)

Better to play at A as it is sente.
I think if white plays now he can win because the territory balance is equal (including the komi).
He has good moves at B,C,D,E or F.]
