Life In 19x19

Just ended this game played white and lost. First picture shows end of game second picture is what could have been.
What is the correct move for white to save the group that was lost?

My guess was that playing J-12 in bottom picture, would've saved the game (if a - s is left to right and 1 - 19 is bottom to top ). Would this have created two eyes and saved the group and the game??

Thanks for all responses.

I cannot speak for others, but that picture is way too big for me to be able to see enough of it on the screen at one time. I think you need to edit the picture to be a smaller size.

Hi jawon,

Yes. To save that group, White must make a second real eye.

One coordinate system goes from A1 (lower left 1-1 point) to
T19 (upper right 19-19 point), skipping over the 'i' column.

This forum uses such a system for diagrams and SGF.
There is no 'i' column. 'H' goes directly to 'J'.

Your "J-12" for White would be K12 on this forum's coordinates.

For future reference:

• Your 2 photos have different orientations. One photo is rotated 90° relative to the other. This can be confusing when you refer to coordinates about them.
• See How to Make Diagrams .
• People use all different kinds of displays when browsing this forum, from the 5K Mac screens to small phones (like I'm using right now). It's helpful for you to think from the viewer's perspective.

Example: this is how your photo appears on an iPhone 4S (full screen shot):

Here are the images in SGF format (unless I made mistake in transcribing).

Yes.

P.S. After you live, where does black need to defend to avoid you killing his group?

So this is better than what the proverb suggests ("die in sente; live in gote"). This is a case of "live in sente".

Making the second eye is correct. But here are a couple of interesting variations.
