Tapir: I like experimenting with shimaris like this given here. Recently I see W6 more often played against me. I'm unhappy with my results as black so far. Questions: Which important variations are to consider, how to evaluate the results in the variations given.

An usual opening with me playing black (1-6)

Continuation I

Dieter: Usually, White will W4 without W2 here. Instead of B5, Black can invade at a, after which the W2-B3 exchange becomes a loss for White (I think).

Continuation II

Continuation III (violent)

Tapirs kyu analysis: Cont. I and II are a bit submissive, because of B3. Especially in Cont. II the lower right corner enclosure is hurt by the stable white group in front of it. Cont. III looks better for black (but it is so violent early on) actually I played the enclosure etc. to make my opening more calm and understandable, but this is probably a misconception. How would you play?

Note: I was very impressed with White in Cont. I since fellow SDK seldom defend their groups like this. (However in the actual game black took the side later, and white the corner.)

Dieter: cont III is the pro continuation (gobase search only). You are right about B3 in the others being submissive, it seems. Yet it is submissive for an account of max 2 points, I think, so if you want a peaceful game, then those continuations perfectly fit your intention.

Tapir: I'm very impressed by numeral values for such early plays, especially since it starts a somewhat violent line and the actual outcome depends on the fight to come... I have no idea how to come up with such values. 2nd thought: as a 4/5 kyu up to early dan grades I may allow for such 'inefficiencies'.

An usual opening with me playing black (1-6)

Dieter: 24 hits on gobase for this position. 13 a, 6 b, 2 c and 1 each for the rest. After a the widest path is as in continuation 3 above.

Myself I would play one of the large pincers, presumably the far high one. I'm an influence oriented player, even moyo-oriented, says Dinerchtein's test at go4go.com.

Tapir: The test says the same for me, I wondered, because I thought I became more territorial lately...
