Texas Hold 'em

Got myself into a regular poker match, ever Tuesday after work at a pub called O.B Camp. I went last night and got wasted, went all in on a guy who I thought was bluffing, after I went all in he looked at me and said "You know that I'm American but did you know I grew up in Vegas" Won't be doing that again. So I've been reading up on strategies over the net, gotta get my 10 bucks back!
