Regarding your comments about the "poor" guy and his losing money, my friend is also not the wealthiest guy around and he has a young daughter and a new born son. 4 days after his son was born we were playing at his brother in laws house. After taking several large pots down that he was the only caller to the river I said, "your baby needs a new pair of shoes, but not tonight."
He laughed it off and knew it was a joke.
There are NO FRIENDS at the table. NONE. I will take your last penny and feel no guilt about it. And if you take my last penny, you should feel no guilt.
All of us know that after the chit chat stops and the cards are dealt we are all enemies.
The games are friendly, the ball busting and sarcasm is non-stop, but the play is as serious as it gets.
You see a man's weakness and you exploit it for your own gain, hiding behind the facade of "the game".
Something I learned long ago is that you announce BEFORE YOU START PLAYING what time you're going to be leaving the table.
There's nothing worse than holding everyone elses' money and saying, "well, I guess it's time for me to leave."
