Triple Draw - Problem Situations in 2-7

[Luv2DriveTT]

I've been playing enough Triple Draw lately to notice some problem situations I'd like some advice on. I cannot find the relevent sollutions in Super System II, perhaps the combined minds of 2+2'ers can point me in the right direction. I've noticed quite a few more, as I have time to collect my thoughts I'll continue to post them here. 2-7 is an amazingly complex game, it is fast becoming a favorite of mine.

After the second draw Hero has 23456. Lets assume that the first draw there were no paired cards, and no aggressive actions by any players so far in the hand.

1) Which card is the ideal discard if the player is first to act?
2) 1) Which card is the ideal discard if the player is last to act?
3) How does the decisions change when facing a large field of opponents?

The Hero is in the Big Blind and checks pre-first draw, hence he starts out of the box without a duce, 3 or 4. After the first draw Hero has 566789. The action is checked around prior to the second draw.

1) Which card is the ideal discard if the player is first to act?
2) 1) Which card is the ideal discard if the player is last to act?
3) How does the decisions change when facing a large field of opponents?
