Hi! I made a video on glue and gluing techniques you might enjoy: https://youtu.be/55lb2KzSiwg

The short answer to your question is CA glue. I prefer 50cps.

FWIW, at the Michigan State Tournament, the winning Div. B bridge competition score was 3861. I have no idea what the Nationals Div. B scores were.

Keep an eye out for a new video soon!

Then I'll move on to Div C to see what I can do ...

Any 2022 Nationals Bridge Scores out yet?
