Donald Catlin Gaming Guru - Page 6Weak Three-Card Straight Flushes in 9/6 Jacks1 November 2009
Let me begin by saying what I mean by a weak three-card straight flush.

A very weak three-card straight flush is one that is double inside and has no high cards. This latter ... (read more)

At Risk or In Play?6 September 2009
I recently received the following e-mail from one of my readers:
Hi Don,
I've been reading about the "doey-don't" system of placing both a come and don't come (or pass and don't pass) wager. The books claim that this reduces the house edge on the standard line bet. I think 0.92% is cited. The pitfall is 12, which loses on the come but only pushes on the don't come. ... (read more)
Take Down the Eight on the Comeout?14 August 2009
I recently received the following letter from one of my readers.
I'm very interested in the effect on the house edge calculation for a placed 6 or 8 when one is left up on the comeout with a pass line bet. If, say, a $6 place bet on the 8 is left up with a $5 pass line bet, the total amount at risk is $1 and the payoff for a win is $7. ... (read more)

Parrondo's Paradox5 June 2009

If asked why I would probably have said something inane like it seems clear that it is counter intuitive. ... (read more)
Interpreting House Edge, Part II2 May 2009
Last month we observed that one must be careful when interpreting the house edge. This month the lesson is that one must take care when calculating it.
A common wager at Craps is to place both the six and eight. When placing the six, for example, one is wagering that the shooter will roll a six before rolling a seven. ... (read more)
Interpreting House Edge, Part I3 April 2009
In general terms the house edge is a statistic that tells you how much of the money that you wager is going to be retained by the casino. There are some technical issues that mathematicians love to squabble about, that is, how should one handle ties and should the figure be based on the ante or the actual amount wagered. ...

Wild Six Card Draw Poker6 March 2009
This past November I attended the Global Gaming Exposition (G2E) in Las Vegas. There was the usual array of new slot machines, video poker machines, and table games. One of the table games caught my eye because one of the co-owners is my good friend Stanley Ko. Stanley, like me, is a gaming analyst and in my opinion one of the best in the country. ... (read more)
