No reads, 4th hand in. My gut instinct here is to raise raise raise me aggro aaaaaaaughhh but then when I think WHY to raise, I don't think it's compelling. It's likely that I am behind, I'm not going to get a better hand to fold here either.

I don't wanna fold though this pot is huge and I don't know the guy. 3 clubs isn't fun though and with an Ace, hell this is marginal.

So the correct line is to call it down unless a 4th club comes? Maybe? Yeah, I vote for that. Am I right?
