When to fold aces on the flop?

[blankoblanco]

Scenario is this: You're at the final table of a $100 Buy-in tournament with 6 players remaining, with relatively even stacks. About 750 players started the tournament.

Blinds: 4k/8k with 1k antes
Average Stack: 200k
Hero's Stack: 240k
Villain's Stack: 240k

You're in the c/o. It's folded to you, and you look down at AsAd. You make your standard raise to 24k. Button and small blind fold. The BB (villain) is a very good online tournament semi-pro. He has a TAG style though he is capable of rare big bluffs. The same applies to you, and villain knows this. He elects to call your raise. There is now 58k in the pot.

1. The flop comes Kc Qh 9s. Villain leads out with a bet of 30k. You choose to raise to 80k. Villain thinks for a few seconds before deciding to put you all-in. There is now 218k in the pot, and it costs you your remaining 105k to call. Call or fold?

2. Same betting, but this time the flop is Qc Tc 8h. Call or fold?

3. Same betting, but the flop is Kh Jh 6c. Call or fold?

4. 9h Th Jh. Call or fold?

5. Ks Qs Jc. Call or fold?

6. Jh Jd Ts. Call or fold?

I made up the situation... just trying to learn. I have a hard time folding aces in situations like these, which often gets me in trouble because 1 pair is still only 1 pair. Is it usually too difficult to put villain on a range of hands in scenarios like this that we often must call? Any insight anyone can provide are greatly appreciated.

With 30 BB's you shouldn't be raise/folding any of these flops. I do think that calling is better than raising on some of them, though, particularly the JJT flop.

On the JT9h flop, I'd probably call and re-evaluate.

Well consider one of the flops where you think raising the flop is reasonable... why is it out of the question to fold once they push? Isn't your opponent very often telling you they can beat one pair?
