Um, pretty much anywhere! I play/played SNGs at Party, Boss, Crypto and Pokerroom and they all have ten-man SNGs. I was being a bit tongue in cheek in the above post, but there is truth in there too - I reckon myself to be among the stronger players in the SNGs I play; therefore, on average, the 10th player is likely to be weaker than me, so I want him playing so I can pick up a proportion of his equity.
