Blackjack at the casino: "He/she took the dealer's bust card!"

Splitting is only a good idea with paired aces or paired 8s, though, isn’t it? It seems surprising that it would be common enough to make a difference in the number of cards dealt.

No, Basic Strategy says to split in a number of cases besides Aces and Eights. You ALWAYS split Aces and Eights regardless of the dealer’s card, but there are other cases where you should split depending on the dealer’s card. Here’s the full chart: 4-Deck to 8-Deck Blackjack Strategy - Wizard of Odds
As you can see, the only pairs you never split are 5s (where you should double in most case) and 10s where you should stand.

Yeah. If the dealer has a 6 showing, you want to shovel as much money on the table as you can. Split everything (except 5’s and 10’s), double on everything (within reason).

BTW, if you ever see someone split 10s when they otherwise seem to be playing reasonably close to Basic Strategy, they’re probably counting. Splitting 10s is sometimes the right move when the deck is 10-rich. I never had the guts to split 10s when I counted. It seems to be a guaranteed way to grab the pit boss’s attention.

FWIW, I used to play pretty regularly at a table a lot like this. About 25 years ago, there used to be a gaming outfit in Tampa/St. Pete that would set up tables at nightclubs where you would pay $20 or so for a stack of chips. When you lost your chips, you were done, but you could play until closing if you managed to keep ahead. When it was time to go, there was no payout; you simply turned in your remaining chips and left.

It wasn’t tremendously popular, but I wasn’t often playing alone either.

Heyyyy!!

That’s why you have no friends.

I have a very good friend who was in surveillance and worked his way up to shift supervisor during the early to mid 2000s. While cheating by both players and dealers/employees was real in the past the house now (at that time, presumably now even more so) watches everyone like a hawk. The “eye in the sky” watches the employees as much as the players. Not saying someone couldn’t cheat or have a partner, but it’s going to be damn hard to pull off for any period of time.
