Remember, suck-outs are the Gods way of telling YOU that you overvalued your hand.
In your examples, I got to thinking about TV poker, where we see these things fairly often. The big difference, and the mistake many of us still make is that there are a gaggle of other factors involved, and we either ignore most of them, or undervalue most of those undefined factors.
Learn about position, and table image, and start learning some of the more basic odds
used in poker. There are a whole lot of odds, and calculating them on the fly with a short clock can be daunting. First thing to do might be to learn what odds might be more important in a particular situation. Some of the odds you will get exposed to will not play every hand you are involved in. Or their importance just flat stops mid hand. Example, you flop what you believe is a nut flush A high, with no pair showing, while someone else has flopped a straight flush. You think you are 100% here, while in reality you are 0% to win the hand. You will lose this and scream bad beat.
Start learning to read the other players. First reads will be along the lines of 'is this player just recklessly gambling tonight?' You will notice some players playing 'Loose' and others playing 'Tight'. Most will fall in between.
If no one is respecting your bluffs (AK is after all a semi bluff), perhaps you have got caught recently and often.
I've stopped raging about bad card plays thinking maybe they know something I don't see yet. Otherwise I will continue to try to get my money in with the odds in my favor.
