Transfers Which Are Not Game Forcing ( 21:00:07 FriMay 2 2003 )
When using a 2/1 response as a transfer not forcing to game, i.e. 1S-2C is a transfer to diamonds, my reading is that it is Midchart legal:
"Any call that promises four or more cards in a known suit"
but not GCC legal. If it were game forcing, it would be GCC legal.
The only way a transfer which is not forcing to game is GCC legal is if it is a response to either: 1) a notrump of at least 10 hcp with a range of no more than 5 hcp; or 2) an artificial (1C or 1D) bid which promises at least 15+ hcp.
