Fortunately Steve, the player that holds for the draw, will lose more often than they win, so in the end, you don't lose as much as you take back.

Encourage them to go for the long shot draw, it's money in the bank.

I know it's aggravating when they hit and "steal" your pot, but keep in mind, they are doing this over and over, so the odds are, you'll get their money.

Never wise up a chump

I tried for years to help one guy, who would stay when he was beat and couldn't even draw a winner sometimes, and the rest of the guys I played with got mad at me, so I finally learned to shut up and enjoy the profits.
