Alright, I only looked at the first few moves.
And note that I'm only a DDK, but a little further down the road than you
So here a few ideas:- Don't play atari just because you can. And if you do atari, wonder about from which side you want to atari. Think of what will happen after your opponent answered. Is the position in any way better for you?
- Keep connected (move 45). That one stone you sacrificed was important. It was keeping your stones connected. After it was gone you had two weak groups to fight with. No one wants that.
- Sometimes it's better to simply connect to protect a cut. This makes you more solid. You need to look out for moves like 56.
- Don't always go for contact moves. This is very important. Contact moves take away a liberty from the opponent's stones, but also from yours. Often they make your position worse. They're only to be played with caution. Look at move 51. One point higher and your black group was safer. You make a bamboo joint, a safe connection. Next you can try to make some kind of base in the corner.
