When to Split in Blackjack: The Moment of Truth or a Risky Gamble?

Alright, I’ve been playing blackjack for a minute, but there’s always this one moment that trips me up—when to split in blackjack. Like, do you split 8s against a dealer’s 6? Or 10s? I’ve heard people say to never split 10s, but sometimes it feels like the right move, y’know? The math says one thing, but my gut says another. Can anyone explain when the right time to split is and why it feels so nerve-wracking every time?
