Does staked on the same horse to win, place, or show in a race mean staked on the same horse to win, to place, or to show in a race?

 

[emsr2d2]

Yes. They mean the same. There's no need to repeat "to" before the second and third verbs in the original.

 

[GoodTaste]

But what does staked on the same horse to place/show mean?

 

[probus]

In horse racing, to plsce is to finish second and to show is to finish third. That is in America, at least.

Betting "across the board" allows you to select a horse and you will win some money if he/she finishes 1st, 2nd, or 3rd. If you only bet on the horse to win, and he comes in second, then you win nothing.

If you bet "win, place, show" you will win some money if the horse finishes in any of the top three positions. But, obviously, more money for 1st than for 2nd or 3rd; and more money for 2nd than for 3rd.

Depending on the odds, you could lose money that way even if your horse comes in first.

 

[SoothingDave]

I meant "win" in the above as "receive some winnings." Depending on the odds, and the finish of the horse, you may not actually come out ahead financially. If you bet $6 (2/2/2) and collect $4, you have "won" something, but you did not profit.
