Some people think "improve your bidding" seems to be about adding more and more gadgets to their bidding repertoire. That's not necessarily true. I recall seeing an article by Larry Cohen a year or two where his thesis was that most players would be better served by thoroughly learning how to use the tools in their existing bidding toolbox than adding more tools to it. It something that resonates with my experience a lot.
This reminds me of an experience that I had a few years ago when I was teaching a class and one of the players said she was playing with her friend (who was there) and her friend said they should play Jacoby transfers (which I was pretty sure neither of them were ready for.) "Oh no, it's really easy! She just bids 2D to tell me to bid 2H and bids 2H to tell me to bid 2S. We got this."
So I gave each one of them a hand and had them bid it. They got to 3NT with 16 opposite 2.
I gave them another hand pair. This time they played in their weak 5-2 fit in game.
Third time's a charm! They played in 3H (from the weak side!) with a 5-2 fit and 16 opposite 3.
My student suggested to her friend "Maybe we better not play those transfers. We know what we're doing with Standard."
