It never ceases to amaze me at the randomness of house rules at home poker games. I'm not sure how well some have been thought out.
Probably because every home game plays a little bit differently. As a host, I'm putting rules in place so that it increases my enjoyment of the game while at the same time tweaking them as needed to fit my group as a whole. These are home games, not casinos. The home game isn't running 24/7/365. its running once a month, in 7 hour spurts.
I use half the deep stack rule and it works. This might not work at another game so that host would have to recognize that and adjust his rules accordingly.
As long as everyone knows the rebuy rules prior to the game, then there shouldn't be any problems. If they don't like it, they don't have to play.
