Hi Joaz,

As mentioned multiple times now, DL is on a browser; I'm not sure which device is doing the playout calculations. It fails to load on an ancient iPad (maybe stylesheets issues), but it works OK on an iphone5. The point is unless you have an ancient device like a first-generation iPad, you can use DL yourself. I added the extra :white: stone for dame, not DL. The mirrored knight's :white: was a typo. Anyway, it seems higher-end LZs like the game move :b11: 2-space low jump or the 2-space high jump slightly (~2%) better than the 1-space jump :bc:, within the margin of error, all playable by humans. But I wouldn't play the 1-space jump :bc:; just my preference.

I managed to do so. :)

It is rated around 3% less than the 2 space extension on the right side, which is close to the margin of error.
Hi Bill, I also figured out a way to get an approx. from DL; DL also shows ~2% lower for the 1-space jump :bc: (~68%) than the game move :b11: (~70%), followed by a :white: peep, yes. A slightly different variation:

Higher-end LZs may give different variations.

LZ 202 has a pretty interface.

Thanks for the advice, Ed, but I still feel that I'd be making a deal with the devil.

I don't like black 1 in this diagram, I think black at "a" is better.
The reason is that white is strong on the lower side (in fact, all of white's moves have been invested in the lower side so far), so black wants to stay away from white's strength.

The sequence in this diagram shows one way for white to exploit black's indiscretion, by turning black's group into a target to be harassed.
(I saw the other post showing a maybe smarter way for black to respond with a diagonal move instead of 3 here, but this is to keep things simple - in reality, white's best move may not be to directly peep at 2 either).

Also, this being a handicap game, there is extra reason for black to try to keep the game simpler and not create unnecessary targets for white to attack.

Is 5 for 6 a good or bad exchange for black? Might be better to directly descend at 7 to not help white build eyeshape, but it's still painful to play a gote move on 2nd line like that. Also turn at b another idea for 5, aiming to develop in the centre and play c shoulder hit later.

I like to make the 5-6 exchange,to force white to respond (while later, white may just jump at a if black 5), but I can see why one may also want to play 5 directly at 7. In fact, LZ seems to agree with you.

Anyway, these are small differences we are talking about, I just wanted to point out the high-level consequences of black 1 vs black a, for the black player in a handicap game.

For sure, I agree that extending is good, doubly so in a handicap game.
