This board happened to our dutch teammates in the u21 pairs. It cost them the bronze medal which they lost by 1 match point. Especially sad since they dominated the qualification stage.
So the polish guy doubled 2H "to show hearts" while his partner thought it was take out. They ...
3S+4H seems about right. I dont like the 3C bid, what do I do when p bids 3D/3S? I guess it worked out this time... I'd rather show both m's with perhaps 3S?
