Game - Non-Forcing, One Round Forcing or Game Forcing in a Standard American 2 Over 1 Auction

Let's play a game. The name of the game is "Standard American 2 Over 1: Non-Forcing, One Round Forcing or Game Forcing?"

I will give you a bid and you have to tell me whether or not it is a Non-Forcing bid (Partner is allowed to say Pass to the bid), a One Round Forcing bid (Partner must bid at least one more time but the partnership is not forced to game) or a Game Forcing bid (both Partners MUST bid until game is reached.)

This post concentrates on Standard American bridge in a 2 Over 1 auction. This is NOT talking about the "2 Over 1" system. In that system, once anyone in the partnership makes a 2 over 1 bid the partnership is forced to game. So ALL (or some people just play most) 2 over 1 bids are game forcing. The 2 Over 1 in this case just means that Opener opened at the 1 level and Responder bid a new suit at the 2 level without jumping. Things are different when Responder bids a new suit at the 2 level because they promise at least 10 HCP. When Responder responds at the 1 level they only promise 6 or more HCP so things are different.

So here is a reminder of what bids Opener can now make that are NON-forcing:
Raising Responder's suit 1 level
Bidding 2NT

Bids that Opener can now make that are GAME forcing:
Opener makes a reverse
Opener bids a new suit at the 3 level
Opener jumps to bid a suit at the 3 level

All the rest of the bids Opener can bid are ONE ROUND forcing.

You might be wondering about that reverse statement. You are probably thinking you didn't think reverses were forcing to game. This is true in a NON 2 over 1 auction. When Opener makes a reverse bid in a 2 Over 1 auction the partnership IS forced to game. When Opener makes a reverse bid in a NON 2 Over 1 auction the partnership is NOT forced to game. The difference is that responder made a 2 over 1 bid to show they have 10 or more HCP. A reverse is now GAME FORCING.

To be extra nice I am giving the auctions in order. This should hopefully make it easier to answer. I will shake them up in another post to make it more difficult.
