For beginners, it's easy to get absorbed by the heat of the battle in a ko fight and to just concentrate on finding the next ko threat to win the local ko fight, but here is a recent game of mine which illustrates the danger of losing sight of what is happening on a global scale. Enjoy.

Go is such a beautiful game.

W44: I don't like this. You shouldn't contact a group you're attacking if there isn't a special strategy like a tesuji. You're move is a tesuji move sometimes but there have to be some other stones to create shortage of liberties. In this situation a move like K7 should have been better.

W72: I Think D10 would have been bigger because it works together with you bottom left corner.

W88: This looks wrong to me because he (should) gets an easy life and moves into your corner at the same time. Maybe B5 instead ?

But the ko was really well done by you
