5-3 Joseki according to ELF

Gomoto · Post by **Gomoto** » Fri Jun 29, 2018 3:46 am

The 5-3 move seems to be no longer a valid opening move option according to ELF.
What do you think?

Yaaay!
Death to those 20+ moves josekis!

Of course your pesky opponent might not cooperate! e.g. in 3rd var what if block on side (o17) instead of the simple p16 compromise? natural q15 could get complicated.

I normally do this - surely it's better than the extension?

Another idea for W involves a ladder, and looks bad for W when the ladder works for B:

W can compromise, but the promising looking cut at a will get caught in a geta:

If you're going to claim joseki, I want to see at least 10K rollouts for at least the top three options. Preferably the top five.

And, because even Elf has blind spots, you gotta consider the human suggestions.

Edit: And I want to see play on an empty board. I. e.,

is on a 3-5 point.

A few moves later Elf thinks its winning with 80% (it only considers pull back for white after cut):

I play ladder atari and now I'm winning. Haha, tricked you Elf! Too much depth (it gives a 31 move principal variation after cut), not enough breadth of reading.

P.S. I'm now letting it think more about if it wants to cut, at 100k stills wants to with 77.9% …

P.P.S I checked with LZ #150, it doesn't want to push out but just capture the stone directly, but if you make it push it doesn't want to cut after white block but just defend again. So we can see LZ better than LeelaElf at ladders again.

Updated 5-3 "Joseki" according to ELF:

(Thanks for your input: drmwc, Bill, Uberdude.)

I stay by my word for now. The 5-3 opening move is very questionable today.

Who is afraid of the rusty 5-3?
I play 3-3 and I am not afraid!

Gomoto · Post by **Gomoto** » Fri Jun 29, 2018 2:20 pm

@Uberdude

I use a different board (Kim Ilwan 9p vs Cho Heyeon 9p, four moves) as starting point and ELF suggests this response.
