Different types of "plan"

[Zhende ma?]

Hi all, I've been out for a while but still trying to keep the Chinese up

I have a quick question about the concept of a "plan". I've been reading more Chinese books and papers and I've seen various words for "plan" or "strategy" come up and I was trying to disambiguate all of their meanings. Any help is appreciated:

策略 - strategy?

妙计 - a really good plan?

计划 - similar to the first?

方案 - a plan/project/program?

I don´t know if you feel comfortable with traditional Chinese.

If you answer with yes, you could query the Chinese-English Wordnet for the semantics

of 'plan'. The website is here: http://bow.sinica.edu.tw/wn/
