good game numsgil; i was looking for this thread on the malko forums
nigiri: even
Edit: i guessed right so i take Black;
$$Bc

i never played 5-4 on a normal board, but here i'll try as the sides are a bit bigger than 19x19;
random thoughts on the board: maybe here walls must be used for territory :
consider the sans san invasion joseki:
$$Bc
Click Here To Show Diagram Code [go]$$Bcthere is nothing to attack on the center for the B wall , it does not offer a place to run for stones on the other side of the board.
on the other hand,enclosing a territory on the bottom seems easy. (or going for the kill if W invade the bottom)
Here i think i'll try for 6 stones high territory as much as possible maybe a 3rd line stone + 5th line stone are enough to sketch a big territory ??
$$c almost territory up to the 6th line? is this worth 54 pt of territory ?

i kill an invasion at a on the diag above ??
i wonder the value of playing on the inner corners ???
it might be a usefule reduction foothold if you want to reduce a side:
i repost the diag i posted on the first thread:

Ah, sorry, I wasn't sure if it would be strictly proper in the main malkovich forum.

When I first thought about this board I was guessing that you'd need to play very territorially. But the "ceiling" edge works very well with influence, too. So any corner opening that's reasonable on a 19x19 works here, too, I think.
The joseki won't always work, though. Specifically, I can't say I like this for black:
$$Wcm2
Click Here To Show Diagram Code [go]$$Wcm2That "feels" pretty natural for black, though. So he might play it.
The sides are interesting here, too. It's not too hard for one player to block them off entirely, and effectively cut the whole side in two. So moyos become a real possibility.
In terms of my opponent's move: he's aiming for a moyo no doubt. I like making sabaki in enemy moyos, so this suits me just fine.

It looks like it's there to me? (Unless someone went in to ninja them back).

i was about to complete the shimari on top... but then a splitting move would be natural for W. So here i play on the middle, i try to induce it to come around S19. reasonning is that i hope that i'll be able to surround W in the top right corner and transform the whole top (minus top right corner) in territory
for example:
$$Bcm5 shaded area is expected territory
Click Here To Show Diagram Code [go]$$Bcm5 shaded area is expected territory(i dont really know much about 5-4 joseki)
i consider the 6th line territory as a bonus due to the shape of the board.
Well its proably crasy ramblings at this point
we ll see

I don't actually know any 5-3 joseki.
This is what I'm thinking:
$$Wcm1
Click Here To Show Diagram Code [go]$$Wcm1Then I have to decide between 'a' and 'b'. 'a' takes the corner, but I really don't like the thickness black gets as a result. 'b' aims at making a base along the top side in gote, and giving black the corner, but it's a large corner at the end of the day, and harassing the group is quite good for black.
So I'm leaning towards 'a'.
If 4 is on the other side, I take the ponnuki facing the top with no hesitation.
i kill an invasion at a on the diag above ??
