sequence after 1m - 1M - 2N

• 3C relays to 3D, then pass or 3M = to play
• 3D = check back asking for majors， 应叫人一定有5张所叫高花，也可能有4张未叫高花
• 3M = natural GF. 再叫原套， 6张，否则走check back. 叫另外一套，4-4高花。 都是逼局。For instance: 1C-1H-2NT-3S: only promising 4-4 in major and force to game.
• 3C - 3x -3NT slam interest with openers first suit
