Bruce Wilcox, famous author of EZ-GO has released an interesting hyperlinked SGF viewer and study material on Contact Fights.

Here is an exerpt from the AGJ
AshleyF: I just started using it this morning. Very interesting. Similar browsing idea to Bob Myers' Igowalker™. I've only gone through the first section so far but the Contact Fights material is very interesting as well; quite precise; much like EZ-GO. It almost feels like the priciples were designed for a game engine and then retrofitted for human consumption! It's cool though - I recommend it. Consider it Basic Instinct heuristics for those of us still on the path to making such thing second nature.
