RatPackPoker consults a 2005 Phil Hellmuth

The 'Packs' been playing for a long time and they've developed their own unique strategies and styles but when they first started out they had to have a foundation. One of those fondations came via Phil Hellmuth Jr. and a book entitled Phil Hellmuth's Texas Hold'em.  Here's an except from that book that's called Phil's "Animal Types"

• The Mouse:  is like your old aunt Elda, a conservative type who probably wouldn't even approve of you reading this book.  The mouse-like you-plays only the top ten hands but hates to invest any money with a hand as weak as 7-7 or 8-8.  The mouse hardly ever raises someones else's bet; but when he does raise, look out, because he has the goods!
• The Lion: is a tough competitor who plays fairly tight poker but doesn't limit himself to the top ten hands.  He bluffs with excellent timing and seems to know when the other players are trying to bluff him. Though he plays pretty tight, he's occasionally out on a limb with a bluff or a semi-bluff.  You could do worse than play like a lion.
• The Jackal: is loose and wild, and some days it seems as though he's just giving his money away. Because he's involved in so many pots and raises so often, his play can take some pretty big swings. The jackal's logic seems at odds with logic of all the other players. He just seems crazy! (He's what many of us in poker call a megalomaniac, or sometimes just a maniac.) The jackal can hurt you and himself too with his crazy play, because he puts in so many bets.  But there is some method to his madness.  He's good at raising the pots at the right times (his style of play gives him many occasions to think about what's going on), and whne he does at last win a pot, it's generally huge!  If a jackal runs hot by catching good cards for a while, you may become convinced that he's the best player in the world, but when his cards come back to earth, he can lose money as fast as he won it. anyone think this sounds a lot  like all high stakes online players.
• The Elephant: is fairly loose (which mens he plays a lot of pots) and seems to be from Missouri, the "Show Me" state. He's what we refer to in poker as a "calling station": he never folds when he is supposed to fold, because he doesn't ever believe that you have the goods. Because he's impossible to bluff, no one with much experience ever tries to bluff him-with one exception: can you guess who that is? The elephant keeps feeding the other players his chips, slowly but surely. The elephant isn't very sharp and isn't a very dangerous opponent for most players, but he seems to do well against the jackal, because the jackal keeps on trying to bluff the elephant.

Well there's a nice little excerpt and hopefully it'll help you discern some types of players at your tables. good luck!
