U

Under the gun adj.  Seating position immediately clockwise from the big blind.  The first person to act preflop, and therefore the worst seat at the table.  Wise operators play only the very best hands from this position.  Abbreviated ug.

Under pair n.  A pocket pair lower than any card on the board.

Up adj.  Denotes the higher pair in two pair.  Jacks up means jacks and a lesser pair.  The second pair is not mentioned because its rank rarely affects the outcome.  Jacks up beats tens up, no matter what pair accompanies the tens.  Only if two players both have the same top pair will the second become decisive.  Then the word to use is over, as in jacks over eights.
