My internet poker playing friend was out of town a few weeks ago, and couldn't get his regular site to work well, so knowing I had extra cash in my Party Poker account he asked for a hundred bucks to play there during his visit. Sure fine. A few hours later he lets me know he lost 2, $20+2 SNG tourneys in a row, both by bad beats. His intention at that time was to go into a $30+3 to try and make it back. He is a good player so I wasn't about to lecture him on his bankroll, but here in you will find exactly that.
