Playing 2/1 in a teams of 4 match against reasonable opps, you have the following (uncontested) auction:
1♦ - 1♥
4♣* - ?
*splinter agreeing hearts
Partner's other bids that would have agreed hearts were 2NT=near GF raise or better asking responder for hand type, splinters in the other suits and 4♥ itself.
Are people bidding 4♦ (agreed as last train), signing off or something else altogether?
