I think that magicwand's move is probably better than the tiger's mouth - it's good to stay light and flexible here, I think. But I wouldn't say that a double tiger's mouth would be as bad here as it is in the examples that often show it. The two black stones to the bottom right aren't terribly menacing, so I don't think white has to be worried about survival here, even if he did the double tigers mouth.

So basically, I think that the double tiger's mouth is probably inferior to magicwand's move, but I don't think that it's totally unplayable on this board, compared to the examples in which it's typically portrayed to be bad (in particular, those examples usually show examples where white might have some difficulty living unless he/she plays very lightly.).

Here's an example of a popular joseki that uses a double tiger's mouth that can be exploited by peeps:

Here, black doesn't take advantages of both peeps, but still has the option of doing so. Instead of making a the double tiger's mouth at 3, white could have tried to play out further to try something that seemed more flexible, but in this particular case, it wasn't necessary.

In the current game, I think that flexibility and "resilience" is more important than a stronger connection when compared to the joseki, but I don't think that it's totally unplayable, since the bottom right stones aren't that strong.


Thanks Kirby. :) This is the problem of books. I read them and take the moves to be the absolute truth in all situations... :P Takes a few games or a stronger player's advice to get that out of me.

Sure thing. To clarify, in this case, I think that the book advice of playing lightly is probably a good thing. I'm just saying that it's not necessarily a total absolute all of the time. It's probably good to consider a few different options and to think of the trade offs of each.

Seems an easy decision. Killing H2 would be pretty much worthless. Eventually I would like to do something about D9, and having a stone here helps a bit.

Another mistake by wms, capturing the small stones. I guess I don't need to say how white will respond?

Okay, good. So I wasn't crazy. Thought about asking, but glad to see people have stepped up and responded quickly. Where would have been a better spot to play there? I know wms is wanting to attack the D9 stone, but is there really a way to kill that? Looks like wishful thinking to me.

I was expecting this, so magicwand's connection at B2 surprised me. But after taking another look, the connection is playable as well. The reason is because white has a strong position in the center. Just that the :wc: stone seems a bit out of place when white connects.

The quick and easy answer is: black should settle the two stones at the bottom.

The hard part is how to go about doing it. I'm not entirely sure either.

I would consider :b1: and the intersections around it. Whether black should exchange a with b, I don't know. If black is to play towards the bottom edge, then c is a better direction than wms' cut.

So now I'm looking at how the game is going so far. I screwed up both top corners. And White of course has a lot on the right. So I need to get a lot on either the bottom or the left. To get a lot on the left, I need to kill D9. To get a lot on the bottom, I need to kill H3. H3 is, I think, unkillable right now; it can run out to the center, and if I try to cut it off, then it can easily make two eyes. So the question is, can I cut off and kill D9? Not very likely, but I think I have to try. If the G4 stones become big and strong chasing D9, then maybe H3 will become killable. Doubtful, but maybe.

If D9 and H3 both live, then my only chance is hoping that magicwand really screws up and lets the group in the center die, but that requires magicwand to play stupidly, and I don't think it will happen. I have won games against mid-dan ranked players because they played stupidly when they had essentially a won game in front of them, but not very often and it's not a good strategy to rely on. :)

G4 required a slow, gote follow-up. Black is going remain stuck a step behind.
