At the home games I would often raise in the dark preflop without letting anyone know about it. I have never lost a pot in which I have done this. I have gotten people on tilt when I tell them afterwards I played my hand without looking at my cards. Also this has the added effect of people thinking you've raised in the dark when in fact you haven't (this can be accomplished by a quick peek at your cards when you think nobody's looking, also you can lie). In all seriousness though, I believe this is a +EV move if you pick your spots. Against weak players prone to tilt, it works like a charm. If you have too tight of an image, raise in the dark once and people will think you're a maniac. You do it twice and people think you're certifiable. I have yet to try this in a live casino, I will let you know when I do.
