It really depends on the situation. During the match I am always testing my opponents reactions. I guage their timing and calulate a counter for when they are about to attack. If you do this a few times, they will become hesitant which allows you to apply pressure through psudeo frametraps. An example would be 66K, 2A. (Continued next post)

From here, if they attack, 2A will most likely trade or win completely. So the next time you use this move you could do 66K, BS 6B5B. Then you could do BS 6B, BS 6B6B (if the BS 6B6B hits, do the 66B BE followup then continue pressure with A+B3) You can also take risks by doing moves that tech crouch after you've done a move that leaves you at slight negatives, like WR (K), BS 2A+B. Voldo takes risks nicely.
