This is not a good option, but nobody seems to know. Black should be aware of the important continuations, else there are some pitfalls.

What If instead of playing the hane, white goes for one of the avalanches by bumping at the starpoint?

The simple variation would be good enough for black. You could also choose the more complicated continuations.

I also encounter this online. I usually ignore the white approach and just take the corner. Is this fine too?

@Leon, possible but the variations are quite complicated. I dont like complicated options if I have simpler alternatives ;-)

Your variation starts to go wrong at :w3:, which is sometimes used as a probe if it's hard to decide whether 'a' or 'b' is better, but it's still rare. But let's say white plays :w3: anyway. A question for stronger players is should black continue at a, b, c, tenuki at e, or something else like your move at d?

Different networks evaluate the position a bit differently, but there is an agreement among these three that a (O3) is best. The ELF networks, as usual, are merciless, but I think the best Leela Zero network (68824bbc as of this post) is probably giving results closer to what amateurs might expect. :)

The issue with 'd' is that the clamp doesn't affect :w1: and :w3: much, as they already have enough liberties, and it leaves two weaknesses, plus Tryss's follow-up is really bad for black.

These are the numbers from black's point of view for the different follow-ups. (I don't like to call them winrates, because that's deeply misleading.)

Code:
Move   Best LZ ELF V0   ELF V1
O3 (a)   53.2   71.2   66.5
Q3  (c)   47   49.6   49.2
Q4 (b)   47.1   49.8   48.1
D16 (e)   42.5   44.8   48.2
P5 (d)   26   1.1   2.8

White wants to start the avalanche, not cut at :w5:. I think pros do that, too. However, the avalanche is not quite the textbook one. Take this with a grain of salt as I have found that specific variations jump around a bit depending on the number of visits per play.

Weak groups often get chased around, so while they may not die outright, they are generally not making much territory, while the opponent can get strength and/or profit by chasing them.
