Texas Hold’em Poker
•Community card type poker •Typical full table has nine or ten player•Dealer position identifies with Button•At the casino a Croupier controls the
rounds•Identifying the winner at the
Showdown or when player Bluffs•Awarding the pot to the winner

Final Analysis
Pros
•Fast learning curve (Java / XML)•Meta-level reasoning•Richness, expressivity, dinamicity• Goal-orientedness• Plan triggers• OQL Syntax
•Good set of tools•Ontologies
•Standalone /JADE
Cons
•No CASE tool to assist development•XML ADF files
•Tedious coding of message events•Stability issues•Scheduling mechanism
Conclusions
•Jadex is a recommendable BDI reasoning engine
•Good features, and some lacks that could be fixed
•Open source counterpart to JACK
