It's pretty hard to go wrong in this position. If I didn't blunder at the beginning, and I could have taken away all outside liberties from the Q7 group (which is now impossible because the group formed an eye as it captured a stone at P10), then there was some chance for me. Right now ... not so much.

I feel like I'm missing something, but I guess I'll find out if so...

Actually, I now see that I made a mistake. I should not have allowed Black to play T5. With this stone in place, I've got nothing. Without it, I had this trick:

If Black plays tenuki with :b4:, White lives with :w5: and :w7: (or connects to the group on the right). Darn, I missed another resource. :mad:

Ok, time to wrap up the game.

I guess there is one more trick I will try in a second.
Edit:
I forgot to say that Black lost some points here. He should have played like this:

$$ | . . . X O O X O X X O O X X . X . . . |

$$ | . . . O . O X . X O . . . O O O O . . |
$$ ---------------------------------------[/go]
Instead, I get two, possibly three points which I should not have gotten. Black does get sente, but we are at a stage of making 2-point/1-point plays, so giving me these points was unnecessary.

Small mistakes like this pile up and end up adding to a significant number. Unfortunately, I was too far behind to try to win this way (even if I didn't make the reading error at the beginning).

Edit2:
Wait, never mind. Black stones are in atari after :w2:, so :b3: is unplayable. Even so, I think pushing through should have been better.

What I played was an overplay, and I was going to follow it up with an even bigger overplay. Objectively best was to take the ko. At that point, I should connect (losing two points), but I was going to play this, with hopes of seeing :b3: after which White is alive:

However, instead of the :b3: above, Black could play :b3: at "a" or, better yet, capture another stone on the left. If White fails to respond, Black would kill the entire White group there. As a result, Black gets significantly more points on the left than he loses on the right.

Despite this, Black's lead is large enough that he might as well not care at all about gaining additional points. To the contrary, it is perhaps best to avoid any complications whatsoever. As I said before, a loss by 10 points gives the same 0:1 as does a loss by 100 points. A corresponding tautology holds true with regard to winning.

So, to put it bluntly, why is this game still ongoing?

I was going to resign after failing to live on the right side but, as I said before, I decided to give drishti some endgame practice. He does make small mistakes here and there, so he'll learn more if we play this game out to the end than if I simply give up. I play with him almost every week, so the quicker he improves, the better. Besides, there are possibly some observers who likewise might learn from the remainder of the endgame. Basically, the result of the game is a foregone conclusion, but winning is not the only reason people sit down to play a game--especially a 9-stone handicap one like here.

That makes a lot of sense.

Still the bigger reverse sente. 3 pts. vs. 1 2/3 pts.

Also, when the outcome is so clear analysing the endgame is a bit meaningless - black will play unnecessary moves since they don't matter.

Spoken like a true bot. ;)

My apologies. But bots can play the endgame as though they did not care. ;)

One of the golfing greats (I think it was Gene Sarazen), like many others, started out as a caddy. Reflecting on a pressure putt that he had sunk to win the US Open, he remembered when, as a kid, he would play with the other caddies, and when they were putting, they would say, "This is for the US Open." That youthful practice, he said, put him in a good frame of mind to make the pressure putt for the US Open.

If you want to play a good endgame when it matters, play a good endgame when it doesn't.

I emailed drishti to ask him whether he wishes to continue playing. From his perspective, there is no need. As such, I resign. Thanks for the game. I enjoyed it! :D Given my antics during the game, I expect the hide tags to be epic. Let's get to it.:)

Wow, that is so cool! Thanks for that. I learned something. :) Actually, I remained blind to N18 throughout the game. I did not see that P19 is sente for Black in the final position (I was not calculating in that direction and simply assumed it is 2 points gote).

Also, it seems the folk were initially incredulous that I was as far behind as I thought I was. I'll try to post an sgf file with how I think the endgame should have been played out, and maybe someone can set me straight.

Great comments, by the way! :bow:

I just went back through all the hidden posts. Great comments! Thank you for those. Lots of laughs... The Intrepid is devious! :lol:

I'm embarrassed that I missed the whole P19 situation even to the end. I knew there was something up there, but M12 was the best I could come up with. F18 and J18 were also attempts at making my way over there, but clearly there were better tactics. Thanks again!
