September Tournament: 19x19 DDK

I will play regardless of the format. Unfortunately the initial format is what I would NOT like to play, as I don't have a lot of free time. I would prefer the round-robin or swiss-style format, but any works fine for me.

So please put me on the list!

Have started a separate thread for the swiss tourney. This thread is now purely for the league games.

Arrange your own matches, or just post a game request in the GoDiscussions room on KGS with the subject "L19 DDK league game".

Note: there are two tournaments being held for DDKs this month: a Swiss tourney, where matches are scheduled and everyone plays everyone else exactly once, and this one: a free-form league where you can play as many matches as you like. Join either or both, whichever suits you.

Please post game results here: I will update the standings every so often and you can also check the current results at http://go.keithlard.com/go-tournament-september.

Just a note about the rankings: the winner will be decided by number of points scored (1 for a win, 0 for a loss). People with the same number of points will be ranked by win ratio (eg 5 wins out of 7 games). If two people tie for first place on points and win ratio, there will be a tie-break match to decide the winner.

Just wanted to post my typical hours here in case someone wants to catch me to play a game. I live near Chicago, so that puts me in Central daylight time (UTC-5). I usually play in the evenings during the week, anywhere from 8-11 pm CDT. I play on the weekends as well at various times, but if you want to arrange a game in advance I can be on at a specific time (early or late). If you see me online don't hesitate to ask me to play, or pm me to schedule a time in advance. Looking forward to playing!

Camarao and I played a league game today. Result noodley(w)+ resign.

I think I (white) fell behind in the opening here. Any comments or advice would be appreciated.

Noodley: I like most of the decisions you made early on. A few thoughts:
12: consider attaching at C17. It's not the only option, but it's a useful option to remember. I believe that Fwiffo used that, or something like it, in our Malkovich game.
20: This is the first thing I really question. I am told that diagonal plays like 19 are about as urgent to respond to as contact plays. If you block at R10, black cannot get eyespace there and your stones form an ideal extension (3 spaces from 2 stones). Between S3 and R10, you can't really threaten that group. The block protects against the invasion, which does happen eventually.
64: I like pushing shallower, at G6. This is sente enough that you should still get to reduce deeper, but it's safer to start from the edge of the moyos.

Got to run, but the biggest thing I recommend you look at is 20.

I discussed the game with noodley. We talked about this move for a while and both missed going for the corner :!:

Even so, I keep wondering about this move. What would you do afterwards? Lean against the left side, maybe, to build some thickness and invade the top? There seems to be a danger to make black strong both on the top and the left while white strugles in neutral area, far from friend stones. This is not so easy to play in my eyes.
Do you have continuations in mind?

I haven't seen it too often, but I know it can be useful. As I said, Fwiffo used it in our Malkovich game in the following position:

He said 'I do remember they start with attaching and then black has a choice of hane on either side. If black chooses to hane between the white stones, then white cross-cuts.

It's bad to blindly play moves without understanding them, and since I don't know the joseki beyond the first couple moves, maybe it's bad for me to try to ape it. But I understand the idea behind the first few moves. The cross-cut is a standard technique for settling, so I think I'll manage'. Basically, it allows white in both cases to settle more easily.

Okay, this seems WAY too good for white, so I probably didn't use the best responses for black (or either side). It is complicated and there are tons of possible responses, but many are reasonable for white. I looked it up in Daniel the Smith's joseki site (dailyjoseki.com). What it says is most common is this:

Something like this came up as a reasonably common followup. The point is, white is a ton more stable than he would be as a result of running. (As an aside, 'a' would be a great point for white after this, as it pushes him low.

Thank you, it definitely sounds worth a try.

noodley · Post by **noodley** » Mon Sep 13, 2010 7:59 pm

Threeve and I played a league game today. Result noodley(b)+ resign.

We were both mapping out large areas until an invasion in the corner ended with a liberty race. After the game we were trying to figure out when the best time would have been for White to play on the right side to break up black's moyo.
