In Standard, with opponents silent, if you open 1m - 1M - 2NT, this
would normally indicate 18-19 flattish but what happens when there is
an intervening opposition bid at the 2 level in front of opener?
1m - Pass - 1M - 2X - 2NT, what does this mean now? Is it still 18-19
with a couple of stops in the overcalled suit or is it 13-14? And,
alternatively, what would 3NT be after the overcall?
Thanks
David
