I figured out a way to be super smart.

I plan to play the following move (or "a") at an opportune moment:

After this, the threat of killing White's group on the left will be real:

Thanks to

, White can no longer win the capturing race. I feel so smart right now, I can hardly contain myself! :mrgreen:

I don't feel quite so smart anymore.

I missed that White actually has a ko for life on the left (the exchange of :w6:

for

makes all the difference):

The capturing race with the presence of this ko is much harder to win than the capturing race without the ko--especially since White's last move removed many of my ko threats to connect to the Black group on the right.

However, if I have to fight a ko, I can fight a different (easier-looking) ko instead.

I should be able to win this ko, although I might have to take a loss somewhere else.

Anyhow, I've got many options to choose from for my next move and much counting to do for each of these alternatives. I think I chose to play tenuki in the bottom right corner too hastily (regardless of whether tenuking was the correct thing to do or not). The position is very complicated, so I should have made absolutely sure that I'm not missing any important resources (which I obviously was). I'll take my time this time around.

Some findings:

First of all, I think I'm ahead by 5-10 points if I simply reduce White's moyo and take the big point at G3. Why Edlee did not come around to playing G3 himself is a bit of a mystery to me. Perhaps he does not see that the move threatens to rescue the two White stones in the bottom-left corner:

In any case, I believe Black can win without difficulties after the following sequence:

Instead of :b1:

, Black might actually also be able to start with this move (and maybe even "a"), but I haven't read it out very well, yet:

If this move works, a huge chunk of White's moyo would be destroyed.

That said, the tesuji I mentioned earlier seems to work:

The marked White stones get captured thanks to :b17:

, and, if White does not capture :b15:

, White will connect :b1:

with his group on the right, successfully invading White's moyo.

I need to do some more reading, obviously, but it looks like I have a choice of two pathways to victory--the calm endgame grind or the violent train of ridiculous tesujis. I'll choose the more entertaining way if I can convince myself that :b1:

plus

combination works in all the lines.

Additional findings:

It turns out I could have killed White's group on the left on move :b89:

(before tenuki-ing)--I missed :b7:

A bad misread, but what's new :roll:

.

Another misread was that I thought Black needed one more move to win the capturing race, but I missed :b13:

(which threatens "a").

Now, after White's :w92:

, the capturing race is rather difficult. I'm not sure, yet, but I might be losing the race by a single tempo. That said, perhaps I can still win the race if I first play :b1:

Worst case scenario: I'm still winning even if I don't invade White's moyo.

Reading--a nice skill to have. :study:

This move is either a mistake or the bestest, mostest, most omygoddest tesuji ever. Actually, it's probably just an overplay. After :w1:

, if I persist with the invasion, I don't think I can win the resulting capturing race. Therefore, I'd have to revert to playing the endgame.

Incidentally, I may have overestimated my lead a bit. In fact, I might be leading by only a handful of points. If this is the case, my :b93:

overplay may end up costing me dearly. However, EdLee must first find the right way to defend. Let's see if he does. :cool:

EdLee's last move looks to be a mistake. The difference between this move and between the move I think he should have played is subtle, yet substantial.

These two extra liberties are the difference between me losing and winning the capturing race.

For this reason, EdLee should go for the following variation instead, but it loses some points.

The difference between this result and the following diagram seems to be about 5 points, give or take. Perhaps viewers who can count better than I can would be kind enough to make a more precise estimate.

Hey, EdLee! It looks like you were as busy as I had been over the past year. It'd be great to resume this game at some point. I plan on returning to playing Go in July, so let me know if you'd like to continue the game then.

Hey, EdLee! Should you ever like to finish this game, I would be glad to play!
