General

Pay attention to the other players' bids

• Both during bidding and play!
• Bids are generally trustworthy, with the exception of the dealer possibly getting hooked.
• Seeing whether the hand is underbid or overbid will tell you whether it will be harder to win tricks or to lose tricks.
• Know who has to win or lose the current trick and who still has the flexibility to try and ruin your plans.

Middle cards

• If it doesn't disrupt your plans, try to play your questionable middle cards that could go either way early. That way you have the rest of the hand to adjust.
