Here's a thread that I started several months ago when I started to play:
Old Soko thread
I really haven't played much of the game since then. I can tell you that B2B players (at least in small ring games and tourneys) LOVE to chase and LOVE to call your pot-sized bets on 3rd and 4th streets. You'll just love this game when some gambooler from the Unibet skin of B2B cracks your wired aces by filling a gutshot 4-straight on the river.
Also, since soko is a variation of stud, it might be worth checking out the Stud forum in case they have any info on soko and/or regular 5CS.
