I tried to tell an opponent “I hope you enjoy the game.” The machine gave me

Espero que disfrutes del juego.

with alternatives

Espero que disfrute del juego.
Espero que disfruten del juego.
Espero que disfrutéis del juego.

All because the English “you” is so ambiguous.

Please, which one is correct? Thank you.

1. Espero que disfrutes del juego. (2nd person singular, informal)
2. Espero que disfrute del juego. (2nd person singular, formal)
3. Espero que disfruten del juego. (2nd person plural, formal)
4. Espero que disfrutéis del juego. (2nd person plural, informal)

Both 1 and 2 are correct. Formal versions are the “usted” forms and they also depend on country or region within country, but everyone understands both.

Thanks for your time!

Perhaps, in English, more logically clearly, we say, “Thanks for having spent your time!” :) Hello, David, my Hex teacher.
