Hi Bill, 
There are 4 aces (5 in fact, as the Ace of Diamonds is repeated twice).
 
  
  
  
 
I think it might be the Aces of Spades that is often missing from blog posts. That"s because whereas the other Aces are represented by the following:
(replace first letter with a capital in each case).
ac = 

ad = 

ah = 

Ace of spades cannot be represented by "as", as otherwise the word "as" would be displayed as the Ace of Spades. So for this Ace, you have to type "A*s" (replace the asterisk with a space) = 

(or you can click the emoticons when you make a post).
You"ll also find flops listed like:

 Td 

That"s because the 10 of any suit is represented by e.g. 10 d (remove space = 

)
