Depending on their current hand composition & what they believe their opponents might need, players must choose between drawing from the draw pile and the discard pile. In addition to enabling players to finish melds more rapidly, drawing from the discard pilesstaa can give opponents insight into a player's intentions. On the other hand, drawing from the draw pile may not always result in instant benefits but keeps one's strategy more hidden. Careful thought & knowledge of one's own goals as well as those of opponents are necessary to balance these choices. Melding is the main strategy used by players to win at rummy and is at the core of the game. Players need to become acutely aware of the card combinations that can form legitimate sets or runs in order to master melding.
