How to set note filters to get Flop Hand Value = Gutshot?

[kraada]

Gutshot draws are in Hand Values -> Straight Draws. If you want to make sure you don't have a flush draw or any good made hand you also need to add that you have made hand of one pair (Hand Values -> Made Hands) and that you don't have a flush draw (Hand Values -> Flush Draws and use the Not selected button to make sure you don't have a draw).
