A play at 1 is the strongest move. But you need to know the follow up moves.

Especially if white tries this stubborn resistance

Move 8 is probably stronger than a move at a.

Variation 1b:

Move 1 is not working. This is good for black. (The move at 2 is probably stronger than the play at a.)

black 8 was pass?

P.S. Sometimes my opponents cut instead of empty triangle block in var 1. I've nor seen that in pro games, mistake? how to continue?

This is a very interesting new joseki!

I'm pretty sure.

@Uberdude:

The cut is not a good option for white.

I would not expect white to make that centre push as it loses the 2nd line cut emergency escape route for the corner. If following happens then white is saying a and b miai; let's assume for now giving black a stone at c doesn't make ladder at d work.

Then black saves his stones and encourages white to cut because it damages the outside. Extend of 12 is a tesuji aiming for miai of ladder above or net below, but white can avoid both with pushing to take liberty (we still assume ladder is good for white if white chose to cut).

I suppose black plays this yummy squeeze and white's shape sucks. Where next? a/b/c are some ideas. Maybe white should have pushed at d before that self-damaging second line cut to make sure the e weakness is serious. This is probably good for black, but as black I could probably lose against Ilya Shikshin from here seeing as groups are cut and nothing white is dead and black does have some weaknesses too.
