Was just checking out jgram.org myself for the various uses of 'as if', gotoku, i've not heard of either, but it says JLPT 1 - go figure, i've not got there just yet
Thanks for that.

A useful note is to scroll down to the near bottom of the rashii link to the "see also" - there are some notes for the other words that have similar implciations in english.
