Sorry, just to mention one further thing, for me the key learning point was to flat call the raise pfr. Raising to find out where we are would get him to shove some of his range - making us fold JJ, and the rest of the time he folds the part of his range we beat. Earlier in the book there"s alot of support for repopping of pfr raisers with easily muckable but potentially home run hands like suited 1 and 2 gappers. As apestyles mentions, repopping here turns our jj into any 2 random cards when he comes over the top of us
