Note also that in a tournament players raise their game, particularly if they're the lower ranked player.gaius wrote: I think playing with the idea that you "should be leading" is a bad idea, even if your several stones stronger. At least for me, this nagging feeling that I should come out ahead of any battle against a weaker opponent is the number 1 reason for losing unnecessarily against weaker players. Sometimes, they just play good moves and 50/50 is OK

Re: L19 2011 tournament: PAIRINGS and RESULTS
if white cut as below...black will be in trouble.
i will have to think about why...but i know the answer is to cut.

Re: L19 2011 tournament: PAIRINGS and RESULTS
Magicwand, I don't see the trouble yet... What can white do?
Well, white can live in the corner. Woohoo, that's at least 2 points of cash in the pocket!

Re: L19 2011 tournament: PAIRINGS and RESULTS
Most analysis has White descending first and only cutting if Black descends in turn. See this page on SL. However the idea of blocking above and letting White turn is simply saying that Black blocked on the wrong side to begin with.

Re: L19 2011 tournament: PAIRINGS and RESULTS
that is why i told you that i have to think about it
your second diag is only possible in ddk relm.
so... how about below? i also have to think about this but..i am thinking it will be better for white than plain joseky.

Re: L19 2011 tournament: PAIRINGS and RESULTS
This is one of my favourite positions. There's one more thing to do before the cut, though. I know two variations (hidden for brevity):Magicwand wrote:if white cut as below...black will be in trouble.

is a nice tesuji. Black can't play at 'a':

Re: L19 2011 tournament: PAIRINGS and RESULTS
ez4u, of course I know that your analysis usually does apply, and usually the hane is bad. But how about this case? I see this:
1)
and 
have a beautiful relationship with the marked stone.
2) Black has sente to play
, which is huge and makes ALL black stones work together.
3) Black can still look forward to a move like 'a', to connect all the stones and make the moyo reach out over the whole board.
4) If black would've blocked on the other side to begin with, that would have been gote.
Is really everybody disagreeing with me here? @Magicwand:

needed in that situation? can B kill otherwise ?sente seems pretty big here so i would be tempted to tenuki as W if my corner can stay alive
In theory, there is no difference between theory and practice. In practice, there is.

It's not necessary in an absolute sense, but this is pretty painful locally:

Before all the other questions, I think this is key. The rounds have been slower than expected. Can we make some progress before 2012 rolls around?HermanHiddema wrote:I think the next round can start, right?

Re: L19 2011 tournament: PAIRINGS and RESULTS
I don't claim to really understand this stuff, but it seems to me that although Black has some nice frameworks here and there, he actually has no territory. Is it going to be enough? I think that White has all kinds of invasion points (see 'a' below). Also Black has some difficulty in how to close the bottom right - it has a poor relationship with the bottom left because White has an easy slide along the bottom.gaius wrote:ez4u, of course I know that your analysis usually does apply, and usually the hane is bad.

in the diagram above (marked stone below) might be better at 'b' because it would leave a follow-up play at 'c'. After 
below, I would not feel very worried as White, since the pressure would be on Black to show how to profit from the plays so far. (P.S. I just got back from dinner with a friend, so if none of this makes sense I blame it on the 2 1/2 bottles of wine consumed.

Re: L19 2011 tournament: PAIRINGS and RESULTS
Yes, it can. But October 17th is a big day for taxes ( April 15 plus the standard 6-month extension plus a weekend ) So, I'll probably not have pairings up until the 18th or late on the 17th.HermanHiddema wrote:I think the next round can start, right?

Re: L19 2011 tournament: PAIRINGS and RESULTS
Why aren't the pairings automated, like almost all tournaments are? I think this will do a great deal to minimize effort and have the tournament move along faster.
