(1) You cook well.
(2) You cook good.
When an adverb follows after a verb as in (1), it sounds, I guess, smoother than (2). Yet (2) would not be not proper for there are predicative adjuncts in English. Do you use (2) expression actually? If you do, ‘good’ might show the subject’s property in the activity of the verb, I guess; so this is the difference from (1)?
