There is a new entry to the poker heads-up display (HUD) market called Jivaro. For those that don't know what a poker HUD is, it's software that tracks your opponents while you play and then gives you statistics on their playing style. The idea is to provide you with information so that you can make better decisions in critical spots.
Until now, poker HUDs have traditionally been used by experienced poker players only. Complexity and pricing has so far kept these tools out of the hands of regular poker players, but that might all be changing now with Jivaro.
