A button player opens to 600 and you defend the big blind with A♦5♦ - a suited ace, but a weak one.

Button opens to 600 (3 BB); you hold A♦5♦ in the BB. Best?

WhyA suited ace defends the big blind fine at this price, but be clear-eyed about what it makes: top pair with a five kicker - a hand that runs into better aces far more often than it dominates worse ones.
What happensYou call and take a flop heads-up, kicker problems and all. Pot: 1,300 (6.5 BB).

Flop: A♣ 9♠ 4♥ - you flop top pair, but with a five kicker. He c-bets.

Top pair, weak kicker, and he bets 800. Best?

WhyTop pair here is the classic reverse-implied-odds trap: when you're ahead he has air or a worse ace and pays you a little; when you're behind he has the better ace and takes a lot. Flatting keeps the pot small and his bluffs in - raising only folds out what you beat and grows a pot your kicker can't defend.
What happensYou call, deliberately keeping the pot within a size your weak ace can survive. Pot: 2,900 (14.5 BB).

Turn: J♦ - you pick up a backdoor flush draw, but he fires a big second barrel.

He bets 2,600 (13 BB) into a weak-kicker top pair. Best?

WhyA big second barrel is the exact texture your kicker dreads - A-K, A-Q, and A-J all keep firing while the hands you actually beat check and give up. Calling here pays the maximum at the precise moment you're crushed, which is what reverse implied odds punish.
What happensYou fold; he shows A-J for a better two pair. You lost the minimum, and the chips you saved are a win the scoreboard won't show you.
A weak top pair is built to win a little and lose a lot, so you kept the pot small and let it go to real pressure instead of funding the better aces. "I have a pair" was never a reason to stack off.

With a hand that wins small pots but loses big ones - a weak kicker, a low draw - keep the pot small and decline to pay off the moment the action tells you you're beaten.
