nick, It sounds like you’re paying yourself 3:2 on those “blackjacks” after splitting. Yeah, if casinos did that, I’d be splitting my tens.
But, here on planet earth, drawing an Ace after you split tens is counted as a regular 21, not a blackjack. If it wins (it might push), it’ll be paid just even money.
If you still think you’re better off splitting tens, then I just hope you sign up through my affiliate links.
