Mistake 1: Overbidding

What Happens

You bid more tricks than your hand can deliver. You fail the contract and lose bid × 10 points.

Why It Happens

  • Counting Kings as sure tricks (they’re not — the Ace beats them)
  • Counting Queens as tricks (they rarely win)
  • Ignoring your partner’s likely contribution
  • Being optimistic about card distribution

How to Fix

  • Only count Aces as sure tricks in side suits
  • Kings are half-tricks at best
  • Round down when uncertain
  • Ask yourself: “What if the distribution is bad?” If you’d still win the tricks, the bid is safe.

Mistake 2: Ignoring Bags

What Happens

You take many overtricks per round. At 10 accumulated bags, you lose 100 points.

Why It Happens

  • Not tracking bag count across rounds
  • Trumping tricks you don’t need
  • Bidding too low and winning extra tricks unintentionally

How to Fix

  • Track bags every round — write them down
  • At 7+ bags, actively avoid overtricks
  • Don’t trump unless your team needs the trick
  • Bid accurately to minimize the gap between bid and actual tricks

Mistake 3: Poor Nil Support

What Happens

Your partner bids Nil, and you don’t adjust your play to protect them. They catch a trick and your team loses 100 points.

Why It Happens

  • Playing your own game without considering your partner’s Nil
  • Leading suits where your partner has high cards
  • Not covering your partner’s high cards with even higher ones

How to Fix

  • If your partner bids Nil, your play changes completely
  • Lead Aces and Kings to win tricks before your partner can catch them
  • Lead short suits where your partner likely has nothing
  • Be prepared to sacrifice bags to protect the Nil

Mistake 4: Trumping Your Partner

What Happens

Your partner plays a high card that would win the trick, and you trump with a spade — wasting a trump and stealing your partner’s trick.

Why It Happens

  • Not paying attention to what your partner played
  • Automatically trumping when void in the led suit
  • Not trusting your partner’s play

How to Fix

  • Always check your partner’s card first
  • If your partner played the highest card so far, don’t trump — let them win
  • Only trump when the opponent has played the highest card and your partner can’t win

Mistake 5: Leading Spades Too Early

What Happens

You lead spades when they haven’t been broken, or you burn through your spades early and have none for later tricks.

Why It Happens

  • Wanting to “get ahead” on tricks
  • Not valuing spades as strategic resources
  • Forgetting the breaking-spades rule

How to Fix

  • Spades are premium — treat them like ammunition
  • Only play spades when necessary (to trump, or when led)
  • Keep a few spades for late-game control
  • Don’t lead spades until you have a strategic reason

Mistake 6: Not Counting Cards

What Happens

You play high cards when they’ve already been beaten, or you lead into opponents’ strong suits.

Why It Happens

  • Not tracking which cards have been played
  • Playing on autopilot

How to Fix

  • At minimum, count spades played — know how many remain
  • Track which high cards (Aces, Kings) in each suit have been used
  • Note who’s void in which suits

Mistake 7: Bidding Nil with a Bad Hand

What Happens

You bid Nil without appropriate cards and end up taking a trick. −100 points.

Why It Happens

  • Seeing mostly low cards and assuming Nil is safe
  • Not considering how the play will flow
  • Ignoring dangerous cards (one high card can ruin Nil)

How to Fix

  • Nil requires ALL low cards or reliable voids
  • Having even one Ace or King in a side suit makes Nil risky
  • If you have 3+ spades, Nil is usually too dangerous (you might be forced to win a spade trick)

Mistake 8: Ignoring the Score

What Happens

You play the same way regardless of the score situation, missing opportunities or taking unnecessary risks.

Why It Happens

  • Focusing only on the current hand
  • Not tracking the overall game score

How to Fix

  • Check the score before bidding each round
  • Adjust aggression based on score position
  • If opponents are close to 500, focus on setting them
  • If you need a big round, consider Nil or aggressive bids
