I played a lot of poker during my six years in the National Guard. It filled up some of the hurry-up and-wait time.
When I moved to the Lake House, just up the hill from an Indian casino, Doug, one of my new neighbors, suggested we play in a $40 Texas Hold 'Em tournament since the casino was so close.
I didn't make it into the money that night (In each tournament only 8 out of 45 to 50 players get any return on their investment.)
Doug and I went back a number of times over the next few months and I did get into the money now and again, but I decided I'd benefit from a bit of coaching so I bought a book, Dan Harrington's.
It's practical and easy to follow with lots of examples. A good tutor.
The fact that my game hasn't improved is due to my own shortcomings not Dan's. I plan on reading his second volume and soon winning The World Series of Poker. Watch for me on TV.
