Read this 13-card hand
A♠ and K♠ are strong trump winners. A♥ is another likely trick, although an opponent who is void in hearts could trump it. K♦ is less certain: the ace may take it, or diamonds may be trumped before the king wins.
A bid around three is a reasonable conservative starting point here. Four is more optimistic and depends on how the king of diamonds and your remaining spades develop. Neither estimate is a promise: deal distribution and table rules matter.
Do not count a trick twice
If you plan to use a spade to trump a club, that same spade is no longer available to win a later trump trick. Four spades do not automatically mean four tricks.
Short suits can create trumping opportunities. A king with supporting cards is often more useful than a lone king, but support does not guarantee a winner. Work through how each hoped-for trick would actually happen.
Use the information at the table
Your partnership is trying to fulfill its combined bid. Listen to your partner and the opponents before finalizing yours when the bidding order allows it. A high combined table bid leaves little room for optimistic extra tricks.
Nil changes your objective completely. An ace of spades makes nil unsuitable under standard rules because it cannot be beaten. Learn ordinary bidding first, then practice nil as a separate skill.
Review the bid after the hand
Write down which cards you expected to win and compare them with the tricks you actually took. A missed estimate can still be sensible; look for patterns across several hands rather than judging your method on one deal.
- Count likely top-trump winners.
- Estimate side-suit winners cautiously.
- Add realistic trumping opportunities without double-counting.
- Consider the partnership target and bag penalties in your rules.
