;C[white doesn't finish joseki. In retrospect, a mistake.

*** Maybe so. Especially as White is strong in the top left. The saying is, Don't play close to strong stones. See variations.]W[nc]

;C[white didn't mind giving black some territory here, because he was undercut at B15 anyway.]W[dn]
;B[cm]
;C[very aggressive. But Leela also recommends this.

*** Good play, utilizing the strength that White has built up towards the left.]W[jq]
;B[ho]
;C[white could link up underneath, so doesn't have to be afraid yet.

*** Leaning attack.]W[dm]
;B[dl]
(
;C[this is probably overplay, though.White is thinking\: you don't learn from your games if you play timid.But there are limits, of course.

*** White should continue to lean. The left side is big now. See variation.]W[hm]

;C[*** Timid. Hane at the head of two stones. See variation.]W[lq]
;C[black felt he was pushing from behind.White felt he was being pushed into a dangerous situation. Both players didn't really like the situation, haha!

*** Yeah, pushing from behind is not good. And White missed his opportunity on the previous play.]B[lp]
;LB[mp:A]C[A would be a good answer for black.

;C[*** Because of Black's strength, thanks to White 40, this is not good, either.

See variation.]W[oo]
;LB[pn:A]C[white, however, is not dissatisfied with the result because the wall has some holes in it. In fact, cutting at A is a good move, one that Leela suggests. One that white thought about for a minute, too.

Go Ian!

So Ian faces kadoban now.

Go Ian!

Oh I'll fight like a lion to keep that from happening!

[Ian Butler]

Third game. It was a good game until I misread a sequence. Then the game turns completely in white's advantage and ends in a pretty big victory for white.

Comments up until move 91.

So it's now 3-0. Probably time for a handicap.

Three choices to continue:
1) Keep playing even. Though that'll probably turn into 10-0, not so interesting for jlt.
2) Playing without komi, me being black. Might help a bit, but victories have always been larger than 6 points.
3) 2 stone handicap games. Probably most equal of all choices.

jlt prefers I decide, so I'll think about it, I also appreciate input from you guys!

[Knotwilg]

Go for 2

[Ian Butler]

Go for 2

Option 2 or 2 stones?

[Bill Spight]

I'd try taking Black with White giving komi.

[jlt]

@Ian: I told you that I preferred that you choose your handicap because each option has some advantages, and I don't know which advantages you value most.

1) Even games: that would be the most challenging for you. I certainly don't think I can win 10-0, but you would be at risk of losing many games, and this may not be good for motivation.

2) Reverse komi (Bill's suggestion): the games would resemble normal games, but even if you make a first big mistake like in game 3, the game won't be lost, so it will be easier for you to keep your fighting spirit.

3) 2 stones: the games may become balanced, but less challenging for you.

I case you wonder, when I play against a stronger player who lets me choose my handicap, I choose H/2. For instance, if he is 6 stones stronger, I take 3 stones. In this way I lose more than I win, but I don't lose all the time.

[Ian Butler]

I think me taking black and having reverse komi would offer the most interesting games for both of us. Let's try that, we can always change it if it doesn't work out

[jlt]

OK, so let's do that for a few games and we'll see if we have to change. We couldn't play this week, so in the meantime I posted a few games of mine, so that you see how I got slaughtered. I won't be able to play on Sunday, but Saturday should be OK if you are free, please PM me.

[Ian Butler]

Game 4. Black has a reverse komi of 6.5 points.

White wins by resignation.

My main thoughts on the game:
I felt I took a good start and made it hard for white in some areas. Also because of some good tenuki's and keeping the tempo up for black.
Then something very typical for my games, it all falls apart when the opponent shows superior tactical thinking and things get cut or shapes get ripped apart.

Still probably my best game of the jubango so far, only my middle game is not up to the level to win or to keep a lead.

Apparently your biggest mistakes were:

1) The last one.

2) which should have been at N6 (we noticed it this morning)

3) . Leelazero says that C5 would have been a better local play. This move separates the white C8 group from the corner group. White can also disconnect Black but C8 is not alive, so that's a fight...

BTW we forgot to schedule the next match. I am free for most of next week except Saturday afternoon and Sunday afternoon, please contact me by PM.

Black maintained his level of play for quite a while, except for the 3-3 invasion. But the passive plays, and , followed by the no suji, , lost too much ground.

Hey Bill, thanks for your post.
It's funny, in the review jlt and myself did afterwards, we stopped almost at the same point you stop your review

Also, some variations you point out, we were able to found with the two of us during the review
Then again, you bring some interesting new stuff to the table. Some plays that were considered during the game, but discarded for reasons that turn out to be ungrounded.

For black 83, my first choice was the cap or the hane you suggested, but I started fearing white attaching to the Q10 stone (right attachment), which would also break the ladder for the O7 cut.

Anyway, thanks for the additional insight into our game. Here I was proud of my tenuki on the top side, but it turns out it was too big a gamble?

[Bill Spight]

Here I was proud of my tenuki on the top side, but it turns out it was too big a gamble?

Well, your pincer was really an invasion. And the jlt raised the stakes!

For black 83, my first choice was the cap or the hane you suggested, but I started fearing white attaching to the Q10 stone (right attachment), which would also break the ladder for the O7 cut.

The only think we have to fear is fear itself.

Edit: After the hane, besides threatening White on the right side, Black has threats to make territory in the center and threats against White's top side group.

Also I am repairing the SGF file. I'll have the repaired file up in a few minutes.
