Adam Parrish covers these essential topics in his signature easy-to-understand style. The book has two distinct sections, the first covering preempts and the second overcalls. All aspects of both topics are covered, from when and how to preempt or overcall to responding to your partner's preempt or overcall to dealing with the opponents' preempt or overcall. Each chapter has a quiz to reinforce the material. A great resource for advancing players.
