Joseki: 4-4, 3-6, 4-6, 4-7

hotcoffee: I usually play 'a', here, hoping for thickness and influence on the upper side (- so my choice to play B3 usually implies B5 in my games). - I've put this on the dicussion page, because I'm not confident enough to state that this is joseki, and by so doing mislead other kyus.

B Is this joseki?

I don't know whether this sequence is correct. B5 strengthens B3 and aims for a framework on the upper side, W6 (or similar) is required to stop black playing there next instead, and building a large and strong corner, and B7 (which i have doubts about) blocks white.

White usually tenukis here (at double digit kyu level), or strengthens the right, and later returns to exchange 'a' for 'b', and aim to cut at 'c'. Black also has possibilities to cut at 'd'.

tderz: "Usually tenukis?". White will make a base, e.g. around e, Black can proceed with f.
If White protects the cut d tightly with g (e.g. because there is a Black stone at [circled point]), so does Black (with h).

Bill: Alternatively, because Wg is so close, Black can extend on the top as usual, planning to sacrifice B3 and B5. I. e., if next Wa, Bc.

These could be considered fundamental ideas, not just a special Joseki sequence.
It can only be considered white's hamete for confusing Black, if she first exchanges Wm-Bn before directly cuts Wa-Bb-Wc.

Checking recent changes and finding 4-4 point low approach, tsukenobi, jump attachment brings to light that W6 played at 7 is common.
