Have you ever won a hand you didn't deserve to win? No... of course not. We all deserve everything we get, right?
Seriously, though, if you're a thinking poker player who is knowledgeable about the game, you understand and accept the fact that sometimes we lose pots we should have won, and other times we win pots we should have lost.
You try at all times to have "the best of it" and only risk chips when you have the best chance of earning a reward for doing so. But things don't always work out that way.
