That's the bidding from one table, at others LHO showed big major 2 suiter in one way or the other.
The lead is 2♦, your play ?
It was missed by Meckstroth, Greco-Hampson, Helgemo-Helness and few others but made by local Polish stars.
Quite surprising if you ask me as I am not sure if it would qualify for bridge master level 4
Have fun
