Dedication
Page 5
To Susan, for a wonderful 40 years, and to our children, Brian and Sydney, for always challenging my strategies across the game table and my ideas across the kitchen table. Geoff Much of the work of this second edition was done in the shadow of the COVID-19 pandemic. I would like to express my appreciation and gratitude to everyone who provided medical, food, and other essential services in this difficult and dangerous time. Tank you for helping us get back to the game table. Isaac

献给苏珊（Susan），感谢美好的40年，献给我们的孩子布莱恩（Brian）和悉尼（Sydney），感谢他们总是在游戏桌上挑战我的策略，在厨房桌上挑战我的想法。—— Geoff
第二版的大部分工作是在新冠疫情的阴影下完成的。我想对所有在这个困难和危险时期提供医疗、食品和其他基本服务的人表示感谢和感激。谢谢你们帮助我们重返游戏桌。—— Isaac
