Life In 19x19

Continuing with the sequence I read out...

i dont know what he is thinking but...he must read that i would answer there.
i am alive and his corner life will be ko if he doesnt answer.

No comment here...

I'm glad that I could get a ko in the corner (if I didn't make a mistake). I want to use the ko to strengthen my left group, and also to get a big tenuki, if possible.

Here's a rough possibility of what I want:

I want to fight the ko and get "a" and "b" in sente. If I can do that, I think that I can risk tenuki-ing from my weak group on the left.

I want to take a big point in tenuki-ing to try to close the gap on the score.

I still can't get a ton of points with my bottom stones. Hopefully I can get 20ish. If I can get 20 points or so there, and maybe 12 or so on the top, probably less than 5 in the top right corner... That comes to about 37 points. When white kills my corner group, he'll have around 25ish there, around 12 on the right, and a few points in the center.

This means that I need to get more points than white on the top-left side with my tenuki if I want to win this game. This is going to be very, very difficult since my group on the left is weak. But there is a chance that it could work out, so I'm going to keep trying.

As a last resort, maybe I'll try to make more than 20 points in the center, but that might also be difficult.

I think that the odds are stacked against me, but I'm going to try to try this strategy.

now he has to answer corner or it will be ko.
i hope he knows. if ko...its like white 98% alive

Going according to the plan above...

Still according to plan...

i tried to figure out what he has in mind...now he doesnt even want ko..
i have no idea what he is thinking. i see resign coming soon.

Just for fun...

Oops, I misread.

I wanted the following sequence:

I guess this reverts to the original plan from a few moves ago.

My prospects don't look that great, I think. But I'll see how the next few moves go. Maybe I can get some benefit. After that, I'll do another evaluation.
