After reading the page Australian Blackjack, it says that OBO is "mathematically speaking, this is equivalent to the American rule" (dealer peeks for blackjack). Does this mean that I should use "dealer peeks for blackjack" when looking for a basic strategy chart for a casino that uses OBO?

Thanks in advance

OBO is the same as American basic strategy. Whether or not the dealer peeks doesn't matter. The strategy and EV are the same as long as only original bets are taken with a dealer BJ after doubles and splits.

Had to google OBO - original bets only [at risk].

It means the HE will vary and you should use a calculator to determine it. All else equal, OBO and 'dealer peeks' are good things. If the latter is the rule, OBO makes no sense as an additional rule.

There are four general ways of dealing no hole card:

Blackjack Wins All This lousy rule means that all split hands and DD bets will be lost if the dealer has Blackjack. Unfortunately this is the most common version by far.

Original Bets & Busted Only OBBO means that if you split, the original bet will always be lost and the split hand will be lost if it busts. Double down bets are not lost.

Original Bets Only (OBO) The best version. Only your first bet is lost. DD and Split bets are returned. This is common in Puerto Rico.

Busted Bets + 1 (BB+1) This Australian rule means that you will lose all busted bets, plus one other bet if it exists.

(I think I coined the name BB+1.) Whether or not the dealer peeks is not relevant, and can't exist in no hole card games..

There is some confusion in Australia about the difference between OBO, OBBO and BB+1. Australia universally uses the No Hole Card rule and the BB+1 and OBBO rules are used to compensate the player when the dealer turns over a BJ. OBO does not exist in Australia and as a result important changes to Basic Strategy are required.

OBO: If a player splits a pair and one of those hands bust then it stays on the table until the end of the round. This is the players original bet which is then lost if the dealer turns over BJ.

BB+1: If a player splits a pair and one of those hands bust then the cards and the bet are removed immediately. If the dealer turns over BJ at the end of the round then an additional bet is taken from the box. So the player loses his original bet which has already been removed plus one more(per box). If the player doubles his original bet and the dealer turns over BJ then only the original bet is lost.

OBBO: If a player splits a pair and one of those hands bust then the cards and the bet are removed immediately. If the dealer turns over BJ at the end of the round then an additional bet is taken from each hand. So the player loses his original bet which has already been removed plus one more(per hand). If the player doubles his original bet and the dealer turns over BJ then only the original bet is lost.

ENHC: European No Hole Card rule means the loss of all bets including splits and doubles if the dealer turns over BJ.

In Australia, busted bets are always lost. If no splitting has occurred then there is no difference between BB+1 and OBBO but for any game BB+1 is the better option. The Basic Strategy varies depending on which hole card rules the particular casino is using.
