You may learn about other players' possible melds by closely observing the cards they draw and discard, then modifying your own strategy accordingly. An opponent may not be pursuing that suit for their melds if, for example, they routinely discard cards from sattakinhthat suit, which lets you safely discard those cards without worrying about helping them. Insights into opponents' confidence levels & tactics can also be gleaned from watching their responses and actions during gameplay. It could be a sign that an opponent is holding onto high-point cards or is having trouble forming melds if they show hesitation when discarding particular cards or exhibit excessive caution. You can predict their moves and use this information to help you decide which cards to keep or discard.
