Do you even GTO, bro?
In 2006 Bill Chen and Jerrod Ankenman wrote The Mathematics of Poker, a dense book that introduced readers to "game theory optimal" play. More recently, thanks to online wizards like recent $111,111 High Roller for One Drop winner Doug Polk and programs like PokerSnowie, our understanding of optimal play has advanced considerably.
It's a controversial topic. Indeed, the very term "GTO" intoxicates some, infuriates others and raises plenty of questions. How valuable, really, is game theory?
