Vanunu

Vanunu is a high level variant of stud poker. Daniel Negreanu said, "it remains the most thought-provoking and skill-demanding game I’ve ever played in my life." And that is an endorsement that will get me to try anything. Here goes:
The game is actually “Stud high-low, no break, roll your own all the way, pitch and a buy at the end, with declare,” or Vanunu for the sake of brevity.

I will try and walk you through this one.

It is a stud roll your own game, this means on each street you will get dealt a single down card and choose which card you will expose to your opponents, cards are exposed in the same order as is used for betting (beginning with player to the left of the dealer). All seven cards will be dealt to you this way, you must expose a total of four like a normal seven card stud game. Once a card has been exposed you can not turn it back over, you must continuing choosing one card from among your existing hole cards and the new card you receive, to expose on each round.

It is a high low game with no qualifier (this mean you do not need 5 cards below an eight to declare low).

Once you have been dealt all 7 cards each player is given the option of replacing one of their cards for a fee paid into the pot. To exchange a face down card a Full big bet is charged, to exchange a face up card a full small bet is charged. There is a final round of betting after the exchange.

The game is played with a declare. This means after the final round of betting each player will have to simultaneously declare which way they were going. This is usually down with some kind of chips or tokens. Players discreetly place a number of the tokens in there hand to indicate which way they are going, all players then show how many they put in their hand at the same time. 1 indicates low, 2 indicates hi, none indicate both ways. A player can only win the portion of the pot they contested regardless of the value of their hand. Therefore if only one players ends up going high or lo they win that half of the pot automatically. To scoop a player must win both hi and lo, if he is beaten in either direction he loses both sides. If all players go one way the best hand wins the hole pot.

The game may seem a little complicated, but once you get the hang of it, it’s fun to play. Playing Vanunu is an excellent way to sharpen your poker skills. Reading hands is vitally important to having any success with this game. There are many decisions to be made, and many conclusions that can be made about the actions your opponents take. In any game the greater the number of informed decisions you can make that impact the outcome the game, the larger the advantage a skilled player will have. Well Vanunu gives you many many choices. And plenty of information. Enjoy
