The most important functions are tourn1(), many1(), deal1(), and handeval(). tourn1() playes a Texas Hold'em tournament between different functions which can bet arbitrary amounts depending on their cards, chips, blinds, etc. many1() plays multiple tournaments and stores the payouts for each player. deal1() deals an individual hand of Texas Hold'em. handeval() figures out who won the hand, when more than one player remains and all the cards are shown.

Examples

## out of 1000 hands with 2 players, see how many times 
## both players get at least a straight, if neither ever folds.
n = 1000 
result = rep(0,n)
for(i in 1:n){
x1 = deal1(2)
b1 = handeval(c(x1$plnum1[1,],x1$brdnum1), c(x1$plsuit1[1,],x1$brdsuit1))
b2 = handeval(c(x1$plnum1[2,],x1$brdnum1), c(x1$plsuit1[2,],x1$brdsuit1))
if(min(b1,b2) > 4000000) result[i] = 1
}
sum(result>.5)

## run a Texas Hold'em tournament between 
## 4 players with different strategies, where 
## each always goes all in or folds.
name1 = c("gravity","tommy","ursula","vera")
decision1 = list(gravity, tommy, ursula, vera) 
tourn1(name1, decision1, myfast1 = 2) ## run quickly
tourn1(name1, decision1, myfast1 = 0) ## run slowly, showing key hands
