Need some help on some hands

[Uglyowl]

I have been struggling lately... about 5% ROI and looking to get back around 20%. I play at Party $10+1 SNG's and play 4 at a time so I don't really have a read on players. In the past I have been able to maintain a 20% ROI, but this month a'int happening.

Any opinions on the following 7 hands would be great:

1. Level one (10/15).... I have $800... a raise before of $75, I have AJs... fold correct?

2. Level one (10/15).... I have $785... small blind I call with K2... flop KJ6 (two clubs).... me, bb, and one other in ($45 pot)... move?

3. Level two (15/30)... I have $605... small blind pair of tens... $30 call then $60 raise... move?

4. Level two (15/30)... I have $605... I have pocket kings... one raise of $90... move? what if flop K63 rainbow is checked to you (heads up)?

5. Level three (25/50)... I have $620... On the button.. folded around...(6 players) KT... raise? and if so how much?

6. Level four (50/100).. I have $550.. IN THE MONEY... on the button with A3.. last hand of level.. all in?

7. Level six (150/300).. I have $2046 Small blind Q7... big blind $1022... folded around... move? 5 players

Thanks!
