I attempt to trash the standard bar defense by pocketing their blockers - outright if that's what's on the table. The veteran lizards will cite the "you can't do that rule" and so it begins...bar rules are just that and if you learn them and play within them you do fine.
they were generally called playing honest. you just played honestly and didn't play safes or intentionally miss. and always tried to hit the ball.
it worked fine both ways for both players and the best player still always won. and no fights. unless someone tried to play shit-y on you.
if you wanted true rules you went to the pool room.
I always show noobs who want to play bar (regulur) rules, the follies that only prolong the game. They usually come around to the loose BCA version I play. Helps to have players around to establish the "chic" of ball in hand pool.
