Let us chant our mantras...

Laziness is a virtue... If you have to do something more than once, automate it!

When a player cannot move, that means that a certain set of conditions have evolved. There should be recognizable patterns that can be detected. Otherwise, how would we as human thinking machines play the game.

What you say is true, so we are adding another layer of complexity to the problem. This will make the solution set larger and more difficult to define, since an iterative approach will be necessary to find every winning combination, containing every possible 'blocked' pattern.

Therein lies the inherent challenge in Go.

But also commenting on Johnny Golden's reply, these 'opinions' you mention might also be described as strategem. A way to capture this sort of hint-based event/decision driven system is generally described as an expert-driven system, wherein expert metholodolgy & rulesets are compiled for automatic response with some degree of subtlety.

Wait! This isn't a Parachute, this is a Backpack!
