Great job summarizing Kaysar's true strategy.
A few more things:

It's not true that he only has a long term plan. He has short term and long term. Howie and Janelle's ONLY plan is to win HOH each and every week. Same exact plan that failed in BB6. Kaysar gets that the odds are against that happening, so there must be more to strategy than winning competitions.

His # 1 priority was to stop what Will and Boogie were fomenting which was to unite all the floaters to take out Season 6 first before dealing with other threats. If the SOV had taken out Will or Boogie that momentum wouldn't have fallen apart.

Kaysar's plan is
1) to get the floaters to see there's another threatening group in the house, Chilltown. He accomplished this by making everyone play this week, so that Chilltown was forced to show itself. Had he nominated Boogie/Will, everyone else would have sat back and played UTR, THEN

with Chilltown neutralized, ANY FLOATER who got HOH or any remaining CT would automatically put up two of Season6. Guaranteed. And most likely Kaysar would be one of them, as the guy who took out one of CT. While there is still a chance of that happening, now that CT is seen as a more heavy-duty alliance, there's SOME chance the new HOH would go after them. Before it was going to be S6 as targets, period.

2) sew dissension and chaos in the house by nominating two floaters so that no one feels safe. Break down trust, as the more these people have to play, the more they doubledeal and the less they trust. The less trust, the less unity against S6. This also fosters a sense that S6 is at least a straight arrow group whose deals can be taken seriously, which may bring over Danielle, Marcellas, Erika, or Nakomis.

3) Choosing Nakomis as the initial target. Nak wasn't a vague threat. She and Diane were out for S6 and Nak was the last one standing in HOH. A serious HOH threat, unlike Boogie. (And Will has always played an "I don't want HOH" game.) Nak is only cutting a deal with S6 because she got nominated. Otherwise she was going to win HOH and go after S6, that was a no brainer. Diane sucks at competitions other than endurance, so they intended to let her stay.

4) James - I don't think James plans to jump ship unless and until S6 goes down in flames. He's working up his Plan B, and positioning himself to be taken out after the other 3, but that doesn't mean he won't stick with Plan A if Sov6 prevails. They are willing to take him to F4; he has nothing like that with anyone else. He knows full well how stressful it is to survive week to week with no alliance, and I think he wants to play it differently this time -- for his own benefit of course.

5) Erika totally has the hots for Kaysar.
