I have seen it do some things that suggest it doesn't pay a lot of attention to blocking a position (probably a decent idea against a Kasparov, but not a decent idea against a sub-IM player as it encourages draws). But he _could_ be doing more than I am for all I know. I only know what I am doing, and how well (or not-so-well) it is working, based on games I watch. I do know of one GM that recently told me "I now hate this thing." :)
