Fighting Baiken is terrible with Venom, the most I can say about that match up is to completely out think your opponent. Then again that's what venom always does. I have had 2D go under the S counter, so if you anticipate it then just 2D and set a ball or 2. I've personally found the warp to be helpful when I anticipate a counter, but far less effective than the 2D since the P counter will take you out of the air easily. As always, be careful with your Dark Angels since she can counter through the end of it. Her HS counter (or at least that's the one I think it is) where she flies across the screen to eviscerate your spine can take her out of your pressure unless a pool ball eats her in mid-air, so ya... that pretty gay sometimes. Her claw that she throws can reach across 2/3 of the screen to pull you in if you back off and try to set ball formations, so just keep in mind that she can pull you back to her. I don't have Baiken do that to me very often, but it can be done. If she ever does her K counter, just throw her for being retarded. Play the match safe and make her fear your 2D. That always works for me.
