Track who is close to going out
A small hand is not a guaranteed lead, but an opponent with one or two cards demands attention. Breaking their rhythm may be more valuable than discarding the easiest card from your own hand.
In multiplayer games, consider who acts directly after you. An attack card often affects that neighbor first, making turn order part of the cards value.
Time special cards with a purpose
Do not keep every strong card until the end, but do not spend one merely because it is playable. It is valuable when it slows a dangerous opponent, leaves a useful suit or rank, or forces a predictable answer.
Check the current TableDuel rules because Mau-Mau variants use different effects. Strategy must follow the card actions actually used in the game.
Keep your hand flexible
A cluster of one suit can disappear quickly, but a suit change may leave you stuck. During the middle game, keep continuations across more than one suit or rank when possible.
Notice which suits make other players draw repeatedly. This does not reveal their exact hand, but it suggests which direction may be uncomfortable for them.
Prepare the finish two moves early
Before reducing your hand to two cards, check whether the final card is likely to remain playable. A dramatic penultimate move is poor if it leaves a rare suit or awkward rank.
Opponents save tempo-breaking cards more deliberately near the end. A reliable finish preserves several continuations instead of relying on one hoped-for top card.
