It was my understanding that tha whole string was limited [a-zA-Z_0-9] . 
Are other characters permissible in the string, and we must match this 
pattern? Can the password include #?!$&, as long as there are two alphas 
and two nums with a minimum string length of 8 chars?

If we ARE limited to \w, then  at all times, in any given string of 
[a-z0--9_] , in order for a match to be successful there must by necessity 
be adjacency, it's impossible for it to be otherwise. If it's in a string, 
it's got to be next to *something*. If no such matches are found, it fails.

If we use  [\w]*[a-z_][0-9]|[0-9][a-z_]

1xxxxxxx1 = 1x and x1
xx1xx1xx   = x1 and x1
xxxx1xxx = x1 and 1x
11xxxxxx =  [nada]1 and 1x

It's an interesting puzzle. I'll keep playing with it.
