Hi all,
played a fast game (1m +3x20sec) of Fox server and I ask for some review.
Just for the record: my 144 move was a misclick due to some server delay
Thanks in advance.

Re: 1d vs 1d Fox server. Asking for some review
Well I do think 144-145 was the losing/winning combination. Before that, there were many occasions to do something at the top or top lef It's too late for me now to start a Katago based review but I wonder why you treated that area as not so important for a large part of the game.
Take move 114 for example, where you can play K18, probing Black to give up 3 stones and if he doesn't, cut at J13 next, a fight you can't lose IMO
Even at 76 I'd launch such a semi-attack
At 52 I'm tempted to hane-cut at B15 ...
All of them moves I'd need to check but that's where my attention goes.

Re: 1d vs 1d Fox server. Asking for some review
Hi, Fllecha,
Glad to see you're coming along.
A couple of top of the head comments on the opening, FWIW.
Probably better just to attach underneath at C-14. The two space high pincer is probably a minor error, according to the bots.
Surely not very good.
- 
Ditto.
- 
Quite good.
Non-urgent, I think. Best may be to descend to B-16, cutting off Black's pincered stone and making E-19 almost sente against Black's corner. The keima at C-06 may also be good, making a base while preventing from making one.
Ditto, although C-06 may be worth more and B-16 worth less. But my vote still goes to B-16.
Maybe blocking on the left side is a good idea, to attack
Surely wrong. Better just to extend, like in the old days. The two step hane allowed Black to ponnuki and turn the dubious into a good move.

Re: 1d vs 1d Fox server. Asking for some review
Thanks. In fact during the game I felt that cutting was not big because opponent upper left corner was alive and I felt that was easy for him to escape with the other and hurt my D12 stone, but now that I look at it better that was good move, at least B16 had to be played.Knotwilg wrote: At 52 I'm tempted to hane-cut at B15 ...
I was on tilt after 144 misclick (that is not meant as an excuse of course, but I felt ahead for all the game so far) and for few other moves I played without thinking then I tried to catch up but it was too late

Re: 1d vs 1d Fox server. Asking for some review
Yes, that was a bad moment indeed fo me. After the outcome of the joseki I felt that was wrong direction and thank you move for my opponent. I planned to hide under the carpet my error doing keima on his Q4 (expecting extension) but after his pincer the bottom became jam and I had a poor result indeedBill Spight wrote:

Re: 1d vs 1d Fox server. Asking for some review
is indeed a mistake says KataGo and should be the hane top left:This is one variation, giving a 10 point lead to White.
In my own analysis pre-KG I wondered about this but KG gives a 20 point lead for White now
In this variation, White gets sente and leads by 11.

Here KG agrees the top left is more important and loses 4 points. Before launching the attack however, it wants to press the left side:

Here again, KG agrees attacking the top is better by 6 points and keeping a 4 point lead. KG suggests the following exchange:

in the last diagram I cannot understand 6. Are they really key stones with the idea of cutting opponent's 3 stones?Knotwilg wrote: Here KG agrees the top left is more important and

Re: 1d vs 1d Fox server. Asking for some review
If White doesn't defend these stones, then Black captures them, creating a living group instantly.
If Black connects, then White can attack & defend, for example at
(not checked with KG)
If White plays
directly, Black captures two stones and I would wager even in sente.
Probably Black can look for a more active response, like
here, so that the cut may not be immediately activated. But it's serious aji. And makes territory too.

Re: 1d vs 1d Fox server. Asking for some review
Fllecha, did you realise black can play 4 here for snapback not a, and thus white 3 doesn't save h17 in sente? (Maybe 3 is better at b, so that white's follow up later is placement at 4, depends if black block at 3 first will be likely).
It's too bad to let black capture the 2 stones in sente, so white morally has to tenuki, and then when black captures h17 the white group only has 1 eye on the top, black can likely get a-b exchange in sente, and losing that liberty for black doesn't matter once the 2 stones are captured: White black's knight move surround of 77, defending/saving these 2 stones is thus practically double sente.

Re: 1d vs 1d Fox server. Asking for some review
@ uberdude and
@ knotwilg
ah yes now I get it. What I didn't realize in the game was that saving the two stones would have made his group a floating group. Don't know why that even passed throught my mind
(I noticed the snapback
)
