Tonight, playing $10 NL on pacificc

i was playing tired, i played for a while and could tell i was making some bad moves, so i left and bought into another table with only my tonights profit, so as to not go down for the day if i make an awful call.

position: 2nd last to act, would i say Button-1?
Dealt hole cards:


theres a limper, then it folds around to the guy before me. he raises to 7BB.

at a different site i'd usually put a player on a high pp from that but here i'd say AJ or possibly something weaker, seeing as i'm playing with profit instead of raising for info i just push, figuring i'm playing with profit and i'm fairly sure he'll be the only guy to call me if he does call.

It folds to him, he thinks for a long time then calls, so i'm now putting him on AK, AQ and feeling pretty confident.

ace on the flop.. damn.. he turned over K7 and i took it down

so the question is as to how you play KK preflop..

raise obviously almost all the time, but what if theres a decent raise before you, do you reraise or push, if he reraises your raise do you fold to aces pressure?

if he raises, i reraise, he reraises all in, i'm usually going to fold.. unless i know the player well enough that i can put him on AK, JJ, QQ,

so i think my actual question is.. in general, with out a strong read on someone for AA, do you want to get All in preflop with KK?

i try to put it into a bunch of situations:

general rule, stack size 60-80 BB
Q1
I raise to 5-6BB get reraised to 20-30BB
push or call or fold?

Q2
he bets 10BB
raise push or call?

Q3
he bets 3-4 BB, i reraise to 12-15BB, he raises All-In
call or fold?

Q4
i raise to 4-5BB, he reraise to 9-10BB
reraise, call, push or fold?

thanks in anticipation..
