Name the build before naming your price
Before making an offer, subtract the cards you will give and add the cards you will receive. Then check the intended build again. A resource you consider surplus can still be part of the same road or settlement package you are trying to complete.
Start with a concrete offer that another player can assess quickly. If they decline, change a meaningful element—quantity, resource or timing—rather than repeating the same request. Asking what they need can reveal a mutually useful exchange, but their answer is not proof of their complete hand or plan.
Worked example: the same offer at two moments
You offer one spare wood for wheat that completes a city upgrade. Early in the game, the recipient uses the wood to build toward a new settlement. Both economies improve; whether the deal is attractive depends on the alternatives and the territory involved. Equal card counts alone do not answer the question.
Later, the recipient is one visible point from the target and already has a road to an open corner. The same wood could complete their winning settlement package. Your future city production may never matter. You do not know every hidden card, but visible routes and score are enough to justify treating the offer differently.
Use your alternatives to decide how much to pay
A bank or port exchange gives you a comparison point, not a mandatory price for other players. If a player deal saves cards and completes an urgent build, an uneven exchange may be sensible. If waiting is inexpensive, you have less reason to pay a premium.
Imagine a corner will probably remain free, and your own production can supply the missing card. Waiting preserves bargaining room. Now imagine another player is a road away from taking it. Paying an extra card could protect an opportunity worth more than that card. State the opportunity explicitly instead of labelling every two-for-one deal bad.
Negotiate with the whole table in mind
In a multiplayer game, two players can benefit from a deal relative to the players left out. Refusing all trade can therefore have a cost too. Look for partners whose immediate plans do not collide with yours, and reassess as the visible leader or contested destination changes.
Keep agreements about the current exchange clear. Do not build a strategy around an unenforceable promise about a later turn. Respect the table’s rules and social expectations, especially when introducing new players. For review, record the hand change, the build it enabled and the opponent’s plausible reply; a label such as “good negotiator” teaches much less.
