Guys on a Finnish forum think I am completely nuts, but yes, I only called on river with my nut boat (AAA99).
Had a pretty good read that the other dude had exactly pocket nines. He is a VERY VERY tight player (9/2), and check-miniraise on flop revealed he probably has pocket QQ or 99. If he "only" had QQ, I don't think he would've bet so much on the river with both A and K on board. He knows I'm a pretty tight player also.
And trust me, I've never ever played like this before. But now the read was so good that I just couldn't make myself to raise all-in. Of course had I 3-bet on flop, I wouldn't have this problem on river. But why would I 3-bet if I know the other dude has only 1 out and I can probably get all his money on later streets anyway. Don't want to scare him away.
