re: Poker & does it hurt to opt the iron man chip in?
Gotta be honest, seeing an IronMan chip doesn't really change the way I play against someone. I'll observe their tendencies then play against them accordingly, like I would any other player.
I'm conscious that I'm not everyone though, and it's entirely possible other people might give you more (or less) respect if you're showing one.
Like anything else, I think you just need to observe your opponents and adjust your game to fit. If you're not getting enough action on your good hands, bluff more. Either you'll take down more pots uncontested, or your opponents will catch on and you'll start getting the action you want for your regular game.
