why the usage of ないでも in this sentence?


タダならべつに勝たないでもよかろう How would the nuances change if i said タダならべつに勝たなくてもよかろう?




For the particular sentences, there are little differences, but base on the
explanations of [this website](https://cotohajime.net/2021/01/21/naide-vs-
nakute/),

> ＊「ないで」は行為をしない、ということを言っています。
>
> (ないで means _not doing the action_ )

So,

> べつに勝たないでもよかろう

sounds about the will of the player(?). _You don't have to try to win_.

On the other hand,

> べつに勝たなくてもよかろう

sounds more about the state/result of winning/losing: _It is ok if you lose_.

* * *

To give another example,

  * お金がなくても新しいiPhoneがほしい I want a new iPhone even if I don't have money

is normal. But

  * お金がないでも新しいiPhoneがほしい

sounds a little odd because having money is not an action. (Note that 'お金がない.
でも新しいiPhoneがほしい' is a perfectly normal sentence where でも is used a
conjunction).
