Playing .50/$1 NL Hold 'em.

I am in cut off with $70
Opponent is in BB with $100+

Edit: I have

Folded round to me and I make a 3BB raise since this is what I usually would make in this position.

SB reraised to 10.5BB

I am now putting him on either AK/AQ or a high pocket pair and decide to just call since the pot is already big enough and I want to disguise my hand to some extent. Is this good thinking?

2 players then see a flop off:



Opponent checks and I bet out 1/2 pot ($10).
Opponent calls

Turn is

Opponent now bets out $28, I am obviously putting him on KK/QQ (he is also capable of a big bluff too, so I don't think I am wrong to go all in here even if I consider the % chance of him having a 10)
I raise all in for another $32ish
He calls and flips over:



At first I thought oh my God what a fish but then I looked at the hand and in actual fact I don't think he made any mistakes.

Preflop he obviously was just reraising what he perceived as a blind steal and hoping to take the pot down.

On the flop when I bet $10, even if he knew I had AA, I was giving him odds of the pot's $30 + my $10 + implied odds of my remaining $60. This means he was getting 10:1 on his money, and the chance of seeing another ten or a King was 5/45 or 1 in 9.

Had I have bet $20 he would have been getting nowhere near correct odds to call, and I would instead be posting this in the River Rats section, if he did.

From the way the hand played do you think I should accept that 9/10 times I am against AK or a high pocket pair and playing the way I did is likely to make profit?

Should I just reraise to pehaps $25, and hope KK comes over the top and if he lays anything else dpwn I have still made $10 without risking my entire stack?

Should I have bet out the pot on the flop? I was hoping he was going to check raise me, but obviously he didn't.

Obviously I don't want results oriented thoughts. I think all beginners are terrified of not getting action on their aces and thought I had grown out of that, but then I see this and think am I still doing it?

Any thoughts appreciated.
