JJ preflop: Let's hash this out, k?

[marchron]

Ever since I've been here, the standard Micro-Limit recommendation was that JJ was a cap preflop. In fact, it's one of the things that blew me away about this forum, because I played JJ like a wuss preflop because I was afraid of bad flops, and was astonished that the 2+2 method advocated such an aggressive stance.

But along comes this hand, and a substantial amount of people are recommending to fold when it's three to us, including some heavy-duty dudes.

So what gives? Is JJ a preflop cap or not?
