Weird river call live
So, I'm play 1/2 live last week. Came out +70BB, so I'm not mad at myself at all. But I had one call that was weird.
I had A9c on the button, CO raised to $10. I called. Flop comes As Ts 8h. Checks to me. I feel like there's some draws out there, higher ace possibility, I need some info. So I bet $20. I figure that's enough to eliminate any funny business (the villain isn't a maniac). He smooth calls it. Turn was a blank. He does that check that people do when they pat the table very softly. So I'm pretty sure I'm beat. River wasn't a total blank, but I still feel like I was beat on the flop regardless. CO puts in a $30 bet. Now I'm SURE 100% that I'm beat.
I called it anyway. It was a pride call, or for lack of certainty to my hand strength. I called because I had folded a number of rivers where I felt I was beat recently and I didn't want the table to think I could just get rolled off the river with a half pot bet.
I think ultimately my mistake was showing a set that I was folding to (an obvious) flush, which the opponent did show as well. And later my image did help as I was in a river position with top pair (AQ), but the cards were very bluffable, lot of sticky stuff out. And my opponent opted to just check back a weaker ace which was pretty good for me as I would have been in a marginal spot to make the call if he made a big bet.
Is my thinking off though. I feel like I helped my image, but I also knowingly blew $30 in order to do it...
