Mexican Stud? How's That Go?

[Al Mirpuri]

There are any number of games masquerading under the nom de guerre of Mexican Stud or Mexican Poker. Some are played with stripped decks and the Bug (with or without special rules concerning the Bug) and some without the Bug. Some are played with a normal 52 card deck and the Bug and some without the Bug (with or without special rules concerning the Bug).

Which is the most widely played version of Mexican Stud in the USA?
