Just read somewhere that you can only call a three of a kind a "set" if you have a pair in the hole and a matching card on the board, but if you have a pair on the board and you got a matching card in the hole than it´s called trips.
Is this correct?
If it is, is there something like that for four of a kind, which you can have by both having a pair in the hole or a matching card to a three of a kind on the board ?
