In this edition we are looking at how to bid big hands. What do you do when - all by yourself - you hold 20 (or more) points?
Well, with a balanced hand you can open 2NT. Some play this as 20-21 points, some as 20-22. Whichever (slight) variation that you play the important point is that you can get across your hand in one easy bid. Of course, a 2NT opening bid is a limit bid, and it is partner's responsibility to place the contract.
