@docpop Just throwing at the wall:

- Wisely
- Smartly (may be a good candidate, as in moves in a game, of chess for example)
- Sharply
- Calmly
- Firmly
- Safely
- Soundly
- Canny (hmm)
- Astutely (bad, 3 syllables, but I like the word itself)
- Argutely (yes, that's a word)
- (Take) care
- (Make) sense
- (Be) Smart

... and fix things

Will add more if something else comes to mind.
