Please tell me the meaning of sentences

I am a Japanese studying personally about gambling.
Recently I've been researching blackjack, especially payouts, and in the process I ended up at the ”Wizard of Odds".
As fI look into payouts

"/games/blackjack/calculator/"

I tried to use the calculation system on the above page, but in the choices of the system,
"Player loses only original bet against dealer BJ"
I can't understand the meaning of the above sentence.

So if you like
"Player loses only original bet against dealer BJ"
Could you tell me what this sentence means?

On that page, "Player loses only original bet against dealer BJ" is one of the optional rules that you might run into in some casinos, where the Casino could, theoretically, charge you the same odds for losing, as you'd get for winning. For example, 3:2, or 6:5.

99.9% of the time, the default answer to this question would be "Yes." Yes, means that the player only loses his bet, not a higher amount. If "No" was selected as the answer to this question /option, then the player would have to pay more than his original bet if the dealer got a blackjack, and the player lost. In a 3:2 game, if the player could lose more than his original bet, $10 for example, then if the dealer got a blackjack, the player would have to pay an additional amount of another $5, or perhaps a full additional $15.

I could be wrong, but this is how I read that sentence. Hope that helps.

That means, if you double-down or split and the dealer ends up getting blackjack you only lose 1 unit.

I think the website below has a good chance of helping you.

One relevant section from that site is below:

ちなみに、OBO と記載が小さくありますが、
これは、Original Bet Onlyの略で、
もしプレイヤーがディラーの絵札/１０/Aceに対して、
Double-Down や Splitをしていて、
ディーラーがブラックジャックになっても、
プレイヤーが失うのは、
最初にベットしている(Original Bet)だけということです。

このルールはかなり素敵です！👌


Rough Translation (by Google Translate):

By the way, there is a small description of OBO,
which is an abbreviation of Original Bet Only.
If a player double-downs or splits a dealer's picture card / 10 / Ace , the
dealer uses blackjack.
The only thing the player loses is the original bet (Original Bet).

This rule is pretty nice!👌

Does the “player loses only original bet” rule happen only at tables where the dealer does NOT take a hole card—or can there be other scenarios?

Isn't it sort of the other way round? Here in the UK, the rule isn't applied. The dealer does not take a second card until players have made decisions to double or split. Nor does he peek for BJ. So they potentially lose more than original bet. Under US rules with peek, they simply can't double or split to lose more, as the dealer reveals his BJ early on. I recall reading somewhere of Australian application of the actual rule where they can double or split, but really do only lose original chips placed.

I got the impression that the OP was asking, when would a player with a blackjack ever have money bet in addition to his original bet?

Maybe for casinos where you’re allowed to count your dealt blackjack as an 11 and double it.
