However, those such as @lulu and MrPuffer who reckon that you succeed unless you draw two cards of each suit seem to have taken you as meaning "three or more". Does SSSSHHHHDC count or not? | |

| Jun 28 at 21:38 | comment | added | lulu | With this deck, and that hand, you have to worry about drawing three cards from each of two suits or even three suits. | |
