Draw Poker Riddle

Two men are playing draw poker with a standard 52-card deck. They spread the deck face up on the table so that both players can see all the cards. Player 1 draws a hand by choosing any five cards he wants. Player 2 does the same. Now, Player 1 can either keep the hand he has or draw up to 5 cards. Player 2 can do the same. The player with the better hand wins. Rules: - Cards that are discarded by a player are no longer part of the game. - All the suits are equal in value, so a flush will tie with another flush unless one has higher cards. After a few rounds, the players realize that Player 1 can always win if he draws a certain hand on his first turn. What hand should this be?
