Virtueless
Migeru: KarlKnechtel calls this goban "virtueless".
KarlKnechtel: "Virtueless", of course, because heaven is missing. :) Some interesting properties:
- The centre breaks ladders, which in turn impacts several joseki sequences, I'm sure. But then, I don't know of joseki for 13x13.
- Four points in the middle that have only 3 liberties, like the edges. Could result in some sneaky tricks trying to connect through the centre.
- There is even less than no territory in the centre now. ;)
Agt: isn't mirror go possible without tengen ?
Migeru: I think the refutations of mirror go still work:

Captured stones and komi

A kibitz: you both seem to be treating the gap in the center as a "ceiling". It seems to me that it is more like another "edge" that can be used to make a base. -Darron Shaffer
exswoo:That's a good point. I didn't think of it in that way.

Moves 51-60
- Black 55
- At this point white has secured 85 points (with area scoring) so I think I have lost the game. Migeru

Moves 41-50
- Black 47
- Looking for a place to resign...
- Black 43
- I think I have read this correctly. Migeru
exswoo:Looks like Might've pushed it one too far. (W 42)

Moves 31-40
- Black 37
- Let's try this.
- Black 35
- I don't think I have a choice here.
- Black 33
- If my reading is correct, we're going to see some very interesting stuff happening when I hit the center. Migeru
- White 34
- True...if I was willing go that offensively...which I don't see the need for right now, since you're going to have to work to save those stones for the next couple of moves.
- Black 31
- Is a better? Migeru

- Let's see what happens when you hit the center Migeru

Moves 11-20
- Black 19
- I thought about playing at b, but then white can cut at a with lots of aji.
- Black 15
- Question: does the fact that the center breaks ladders make a not a cut point any more? Migeru
exswoo after playing this far, I think the no Tengen variant has too big of an effect on a 13x13..

Moves 1-10
- Black 7
- Let's make some territory on the top. Migeru
- Black 3
- Now that I think about it, having no tengen makes the 3-4 point better than the hoshi. But that might not be true on 19x19. Migeru
