Hi Mirko, hi everybody,

I think, the simple 26.n16 could be a winning move for black.

Of course after 27.n14 28.m14 black is connected.
And, for instance, after 27.s16 28.r11 is winning ! 29.s10 30.t10 31.u9 32.q13 game over.

So white has to play 27.q15 but 28.q19 seems good.
Perhaps 29.u19 30.r17 31.u14 and I think 32.u16 is winning 33.t17 34.s15 35.v16 36.s11.

So, I think, your back up plan (20.o14) Mirko, was winning because of the strong threat in r11.

Most probably your analysis is correct. In fact after I realized that 17.t6 indeed defends the upper right part, I basically gave up the game.

I think that you analysis is correct, Florian.
After white 5.o10 direction error, 6.n10 would have put black in a very strong position.

I have a problem with the first moves in this game.

What 5th move is correct in this position plz ?

Because, even after 6.n6, I thought I probably already lost the game..

Hi Florian. Basically, the first moves are generaly played in order to prevent the opponent to take a direct path toward his other side. I mean that the "standard" answer to 2.j10 is 3.n11, not 3.k14, the reason why I wrote that you made a direction error (it happens to many of us to make sometimes such errors).
Your 3.k14 allowed Mirko to play the 2-5 "bastard" pattern directly toward the right border, which is a very strong move.
5.o10 has the big flaw that its way to the top is already blocked by o8 and j10.
