This book would be better titled as “All the Stuff I Taught You in the Other Two Books, in Actual Practice using Well Known Poker Players, with Some More Stuff Thrown In, plus, How to Play After the Flop and Read Hands”. It's not just a big multiple choice quiz (though they are in question format), there's a LOT of analysis going on. He uses actual hands between other top pros (not in every case, but most) to illustrate his problems in many cases. Most of the 50 “problems” are actually entire hands (with about 10-15 pages in analysis per).
