I'll add spades based on one extremely unpleasant expereince where I found out that the group I had agreed to play with used two small but crucially different rules from the way I had always played. I discovered this after the major strategy decisions they effected had already been made, and I now do go into any card game with the expectation (or questions about) house rules (or an open mind to the possibility that the way I was taught was a house rule).diaglo said:i'll add pinocle to Chaldfont's list
