Result : 1NTSx+2
After double, if east can't escape, west has no ability to beat 1NT contract. So I want to escape, but there is a issue.
Result : 3♦W-4
2♠ says " 4-6 ♦,4-6♠".
So I would have to believe west Gib could hold 6-4 ♦ and ♠ suits, 2♠ shows opener have great ability to withstand the preference at 3-level.Then I return to 3♦.
