My apologies if this has been asked before. The +1 stud bonus that Longwei Fu gives when at home does that mean for everyone in the posse they get the +1 and become a stud or is it just for one dude in the posse?
No problem asking, this is a slightly unusual card effect! It actually works in neither of the ways described - the bonus here doesn’t turn any of your dudes in to studs or give them bullet bonuses, but rather applies to your overall shootout hand.
Long We Fu’s bonus is applied to your over-all draw hand, rank than any specific dude. Auto-gatling (Auto-Gatling · DoomtownDB) works in the same way, as does Mountain Lion Friend (adds a draw bonus rather than stud, Mountain Lion Friend · DoomtownDB).
So with Longwei Fu at home and a one stud dude, a two draw and a one draw dude in our posse, we’d lead with our two draw dude but effectively count as having two one stud back-up shooters (our one stud in the shootout and Longwei Fu safe at home), so we’d have a total bonus of two stud, three draw. However, none of our dudes would have a higher bullet rating for the purpose of a card link Point Blank (Point Blank · DoomtownDB).
Hope this helps. 
Ah. Makes way more sense now. Thank you!
