Historically, we were all after Masterpoints. We'd collect up the vouchers and then post little stacks of them every few months to the EBU for counting ... and every so often clunk up to the next grade. Then along came electronic scoring and it was all done for us. Magic.
Masterpoints are OK as far as they go. They provide a record of how well (and how much!) you've played in the past – but they're simply cumulative: they don't give an accurate picture of how good you are now. If your partner's been playing for 30 years longer than you, she'll have a vastly higher rank than you do, even if you're just as good as she is – or better. So how to find out your current form?
The answer is the National Grading Scheme (NGS), which the EBU introduced in 2010 – yes, all those years ago. The NGS is pretty handy, in that it provides a live ranking for every EBU player from bottom to top, based on your performance in your last 2000 boards (that's your last 80 or so sessions). *
Imagine you're playing in a vast pairs event consisting of every member of the EBU, and that your partner's exactly as good as you. What percentage would you expect to get? That percentage is your current NGS grade, and it'll range from around 39% (or a bit less) at the low end up to 67% (or a bit more) at the top end.
For quick reference, these grades are divided into 13 playing card ranks, going from 2 (less than 39%) at the bottom end right up to Ace (more than 61%) at the top end, each rank covering a 2% range. At the top end (not that it will concern most of us!), the Ace rank subdivides into ♣A, ♦A, ♥A, and ♠A, the last being 67% plus. So effectively, that's 16 grades in all. Here they are:
2 <39% 3 39%–41% 4 41%–43% 5 43%–45% 6 45%–47% 7 47%–49% 8 49%–51% 9 51%–53%
10 53%–55% J 55%–57% Q 57%–59% K 59%–61% ♣A 61%–63% ♦A 63%–65% ♥A 65%–67% ♠A >67%
What's the average grade, then?
Technically, 50%, which is a mid-8. But given the high number of players at level 2 (we all have to start somewhere!) and the much smaller numbers in the rarefied Ace grades, the mean grade is more like a lowish 7 – see the chart at the top, which was correct in April 2019.
How does it work?
I don't know exactly how the maths works (nor do I want to!) but roughly speaking ...
- Let's say you're playing on a Wednesday evening, where the 'strength of field' (ie the average playing grade) is a bit over 49%.
- Say your grade is 49% and that of your partner is 43%: that's an average of 46%.
- You're a below-average pair, then, in the current field, so are expected to score (say) around 47% (or whatever).
- If you score higher than 47%, your (and your partner's) NGS ranking will go up – the better you've done, the more it goes up.
- And vice versa.
And, of course, if you're an above-average pair (say 53%), you'll be expected to score better than average in order to break even.
What's good about it?
Well, the main benefit is that it provides an accurate measure of where you are as a bridge player. If you're an 'improver', this is particularly useful as you can use it to follow your progress as you become a better, more experienced player. If you're playing in a field of better players, you won't be walking away with fistfuls of masterpoints (yet, anyway), but if you punch above your weight you'll see an immediate improvement in your NGS grade. And the best way of improving is, as we all know, to play against players who are better than we are.
Eventually you'll reach some kind of plateau where it'll level out, of course, and – like stocks and shares – your grade can (and will!) go down as well as up. Most people settle down in one or two adjacent bands: "I'm mainly a 6, but sometimes I'm a 7"; "I was a King for a few days once, but now I'm working my way back up from a Jack ..." But wherever you find yourself, it'll be a reflection of your current form.

* Your grade is a weighted average: the weighting of older sessions declines linearly so that once you've played 2000 boards more recently, they no longer affect your grade.
