At the height of its popularity, Party Poker accounted for nearly half of all online poker revenue. Due to the large number of active games, high stakes offered, and notoriously soft player base, it was mecca for a growing community of online professionals trying to take advantage of the poker boom. Party Poker did not, however, offer heads-up cash games at this time, and so while one on one poker was occasionally played online or at a snail’s pace in physical casinos, heads-up play remained relatively unexplored until 2006, when an ideologically motivated US senator suddenly affixed the Unlawful Internet Gambling Enforcement Act to a ‘must pass’ security bill. The UIGEA created a dubious legal environment for online poker operators in the US and Party Poker withdrew from the market, losing the majority of its market share overnight. Full Tilt Poker, a competing website which offered heads-up cash games, elected to remain in the US market and absorbed much of Party’s uprooted American player base. For the first time since the onset of the boom, a large number of players were competing in an environment where heads-up play was readily available.
The strategy page lets you query the strategy Cepheus uses to play limit Texas Hold'em poker. You can set up a situation -- the public cards and the sequence of betting that occurred -- and find out how Cepheus would act in that situation with any hand.
Please note that the strategy tool may be very slow to respond! Cepheus follows a pre-computed strategy which requires 12 terabytes of compressed storage. Reading the necessary information from disk and decompressing it to answer your strategy query takes a bit of time. If the page is busy, it may take a while to process your request.
