Life In 19x19

Hello, this game escalated into a one-point jump fest towards the center pretty quickly, but I had no idea how to handle the situation properly and ended up losing by time. Would anyone be so kind to tell me what I did wrong? (aside from reading errors of course)

I have some question about . Because it is so close, Black can put pressure on it.

does not look good. All you are doing is running. (Jowa says, Don't run. ) makes look good. If you simply give up, looks silly, doesn't it?

Now is the time to make shape in the center. You cannot afford just to let Black keep attacking your group. Attach at K-14. The White group on the left side is fine.

K-12. Same idea.

Ok, thanks. I was thinking about just giving up my pincer stone, but I was afraid it would be too big a loss. Must stop thinking losing a single stone isn't always such a big deal.

Just wanted to say thanks to ShinLyuu and Bill S. I have got into a similar one-point
jump fest where neither side knew how to stop, so it was good to see the question
and answers in this thread.
