Bid in the card game of bridge
A game try (also called a game trial bid) in the card game of bridge is a bid that shows interest in bidding a game and asks partner to help in making the decision. For example, (using Acol or Standard American bidding) if opener, with around 16 17 HCP, bids 1 and partner responds 2 (showing 6 – 9 support points) opener is in a quandary: if responder has a maximum strength hand, with well positioned high cards, then game will probably make; but the information revealed so far is not accurate enough for either partner to decide whether to play in game or only part score. Originally, opener would make a game try by bidding 3 (inviting game) and responder would then bid game with maximum (8 9) points or pass with minimum (6 7) points. Modern game try bids permit more accurate decision making. Following a simple raise by partner (e. g. 1 – 2), opener bids a new suit either to show extra values or to ask responder to show more about his values. There are a variety of methods to do so including long suit, short suit, or help suit game tries and partnership agreement is required. Whichever method is adopted, responder and opener will collaborate to evaluate the additional information and make one of the following choices: sign off in three of the agreed major; jump to game in the agreed major; jump to game in notrump if the suit is a minor; or make a counter try in yet another new suit. When opener has a very strong hand, slam investigation may also be undertaken.

Because 11 tricks are required for a minor suit game, most players prefer to investigate the possible optimum contract of 3NT before settling for a minor suit contract (game or part score) and thus a trial bid new suit shows a stopper in that suit for NT purposes, e. g.: 1 – 2; 2 shows game going strength and a stopper in spades

When using any of the above methods of game tries, it is common that a rebid of three of the agreed suit is not a game try, but a preemptive strategy intended to inhibit the opponents from entering the auction. Responder must pass, as in this example: 1 – 2; 3 – Pass.

If opener has such a good hand that a slam seems possible even following a single raise by partner, then more information about responder's hand can be obtained by using a game try bid. If responder rejects the game try, opener can sign off in game. If responder accepts the game try, then opener can further investigate the slam.

Fourth suit forcing (conventional and forcing) – When one of the players (normally responder) can see that game looks likely (25 HCP having been shown by the bidding) but no obvious contract is apparent, bidding the fourth suit can be used to elicit more information from partner. Thus holding: and with this unopposed Acol bidding: 1 – 1; 2 – ? game should be possible but is it 4 (if partner has a 3 card spade suit, yes) or 4 (if partner has a 6 card heart suit, yes) or 3NT (if partner has A10x in diamonds, yes)? Bidding the fourth suit (1 – 1; 2 – 2; ?) asks partner to give new, useful information to clarify the situation. Invitational bids (natural limit bids, non forcing) – Either as part of, or following, suit agreement, bids at a level one below game are generally considered to be invitational, thus in Acol: 1 – 2; 3 – ? and 1 – 3; ? are both invitational to a 4 game contract. The invitation should be accepted (game should be bid) with maximum points and declined (by passing) with minimum. For suit contracts this method has largely been supplanted by game try bids as above. However, it is still widely used for NT contracts, thus 1NT – 2NT is invitational to bid game in 3NT
Stayman convention – At its simplest a 2 response is used following an opening bid of 1NT to enquire whether opener has a 4 card major suit. Depending on the answer, responder will pick the best game contract. Long suit game tries This may also be known as 'help suit game try'. In practice, Where the length or strength of major potential contract suit is in doubt, this convention is an attempt to determine whether a secondary suit fit may be enough to proceed to game.
