Deuces Dilemma

So, I reallllllly want to hit Four Deuces on Deuce Wild sometime soon. (And some ROYALS FLUSH, Hellooooooo).

We're playing this Deuces Wild machine over at the Las Vegas Club that offers a $500 bounty on the deuces.

I'm dealt three deuces (see previous post)...

But I'm also dealt a pair.

So I have a pat hand of five of a kind which is worth $20 if I keep it. Or, I have a 1 in 23 shot at $500.

Our liquor-addled brains could not effectively figure out the Expected Value (EV) of the hand. 2000 / 23 = some number but you might still get four of a kind or five of a kind or even a wild royal if you just keep the deuces but its $20 in hand, which one has the greater value, and am I playing short term or long term...

So what do you think I did??? Keep the five of a kind or keep the three ducks and pull the trigger?
