Over a decade ago, the rise of online poker created a kind of conflict between professional players who had made their careers strictly playing live and a new, significantly large group of "online pros." The latter group was mostly comprised of younger players — unsurprisingly — which thereby added a kind of "generation gap" that tended to distinguish the two categories of players even further.
Generally speaking, the "old school" live pros were usually characterized more often than not as so-called "feel" players thanks to their experience with table talk, recognizing tells, psychology and the "mental game," and other intangibles.
