I've had a few bbf'ers comment that I would do better focusing on my play rather than bidding. I know that my declarer play is poor and
I do work through hands with my partner, it is improving, slowly, I could do more. There's often a line of play I failed to see or a bad line I took,
I don't think the problems are suitable for bbf. Most of my posts on here are system problems, I love trying new things and tweaking our system
and bbf is the best place I know to get feedback and new ideas.
Having said all of that, here's a hand I got right, "Advanced" hold off on your answer until some intermediates have had a chance to reply.
After opening 1♣ you find yourself in 3nt, opps have bid spades and lead is ♠8
I will post the full auction later, it will distract from the play problem.
