This is a game between Tryphon and me. I'm playing black, and komi will be 6.5 with Japanese rules

Good game Tryphon. May Shusaku be with you. (ha ha)

This is a standard starting move for me as black. I very rarely play elsewhere as my starting move when playing black. In this regard, I guess I'm one dimensional, but I've never seen any reason not to play here!

Good game to you :) Please, could you give me a number between 1 and 100 ?

Hi, I'm Tryphon and this is my first Malkovich game. I reached KGS 9k but last year was kind of busy for me (my first child was born on September, and my wife's pregnancy was difficult) and I almost didn't play a real-time game since last summer. I play now mostly on OGS.

I like :
- influence
- stones working well together
- attacking
- strange openings

I dislike (and I'm very weak at) :
- endgame
- counting (likely my worst weakpoint)
- complicate sequences (to be true, I like that, but the lack of play these days weakened my play mostly on this aspect)
- josekis

I'll try to explain my thinking the most I can, asking questions when they arise, and I hope receiving answers and hints to improve.

I will only describe in my comments moves that I saw before posting, and not playing sequences of tenth of moves that I couldn't figure without a goban.

I won't use joseki dictionnary.



And now, for something completely different, my first move. I hesitate between playing a common or a weird game. That's why I ask MHO to choose for me.

If the unit digit of the number he'll choose is 0-4, I'll play A (my most common answer), 5-6 : I'll play B (offer a diagonal fuseki, I don't like much), 7 : I'll play C (a move I don't like at all, but that'll force me to think territorially), 8 : D and 9 : E (I love particularly this last, usually followed by another 8-8, but generally I play it with B, and it works rarely well with a turn based game)

If the number is irrational, you're white, otherwise you're black.

Nothing special to say. I use my right to deny a diagonal opening.

I don't like playing komoku as W2, because B can always take one of the two following points, then make the classical joseki :

I know both positions are equivalent, but I don't like W here.

This, of course, is to help my stones work together. Plus I have an affection for the right side. :D

But if I play 4 first, he can come at B and I already said I didn't like that. So 6 first. And if he plays at a, then I play c, I like this move.

As noted, I haven't ever really seen W E17 before. I know it's probably a good move, but I wasn't entirely sure how to respond, so I had to think about it and play it out on a board to see what I could possibly do. I'm anticipating C16 here.

He played what I dislike the most :)

A : usually, I do that, threatening D
B : same idea than A. I don't know which is better, since I know maybe 3 josekis :)
C : erk
D : I prefer play A before
E : I don't like it, there will be 4th line stones everywhere and it will be a mess

I choose A, but I'm not happy, because I take territory whereas I prefer influence. But I prefer secure some stones to attack his ones.

I suppose he'll play around D now.

Question : what are the pros/cons of B towards A ?

Had you chosen 59 at my first question, you'd have been even more surprised :mrgreen:

If you say "May Shusaku be with you", at least play Shusaku fuseki! :P

For Tryphon, if the upper left is settled:
C17 (a) is a low move, and I think its less good than c16 (b). c16 gives black a bit better shape, but your corner is a lot bigger.

I think the first variation is better when white is strong in the area and doesnt want w to get a good shape. Also, there are more variations with C16

The basic Idea behind the 3-5 point is to prioritize the side instead of the corner. The most common point of invasion is the 34 point with one of the josekis looking like this:

[go]$$Bm1 Black gets the corner and the side while white gets a wall.

[go]$$Bm1 Black :b1: gives a inferior local result and is only played when the resulting wall would benefit white too much

In this instance :wc: is already on the board so black approaches far and lets white have the corner. Above is the normal joseki in this position and so I would classify blacks play in the game as too timid.

Good idea Banaan. Maybe using the Shusaku fuseki can become a signature of mine lol Well, after I learn how to play it, that is.

I have no idea what I'm doing here, to be quite honest. E17 is quite alien to me. I figure C16 is a good multipurpose move, though. I'll try it and see where it goes. Although I have a feeling it's going to end up biting me in the rear-end.

The above exchange seems ineveitable, and cannot be good for black. A safer way might be to simply tenuki, or to play as below:

FWIW, black's move might be reasonable if there were no room for white to extend along the top.

[go]$$Bc If the marked stones exist, then maybe it is reasonable,\nfor then the only possible route for development of the white corner is southward,\nand black is in the way.

B is the most natural and I can't see why it could be wrong.

But my opponent key point is my keypoint, so I'm looking avidly at A. But if I play A, MHO plays B and can make a base, whereas my 2 corner stones become under attack. They'll flee, but then A can be attacked.

So, B.

*ahem* As I said, clearly this exchange is good for black. ^^ Actually, I still think it is bad. I bet the global situation is such that a wall on the approached side is good for black's development (as is not the case for this game). Can you provide some games for context? Sorry, I often request this when people pull a DB on me!

Joaz's analysis was local, and in a few of the pro games, the B move also happened quite early (move 8, move 10, etc.),
so there was no wall to speak of -- here are two:
