What are the ways to read the opponent’s hand when he plays the continuation of the bet? What needs to be taken into account? When is it worth answering and when to fold the cards?

When your opponent c-bets, it's always good to look at the board and your current hand's equity. If it's a "wet" board with lots of flush and straight draws, and you have suited connectors that could make the nuts then I would call or raise these c bets. If it's a dry board and you have second or third pair and the opponent c bets and keeps on increasing the bet size, it makes sense to fold your hand because it isn't improving and you're basically bleeding chips by calling.

I don't mind calling c-bets when I have a draw-heavy hand. I will fold hands if they don't improve by the turn or raise as a bluff.

Readless 6max micro stakes. Usually if opponent C-bet you distract Ace high from his range all other cards still in his range
