We're trying to learn IMPrecision and we'll probably have a few questions. So far...

After 1C-1D, 1H-1S, 2D could be 1444 ? or does this pattern rebid 1N over 1D?

How do we relay after...

1C-1D, 1H-1N, 2C-2D, 2H

the notes say that the continuations are like after 1C-1S, 2C-2D only up 1 step but the former can only be 4432s or 3433 while the latter can be 4432s or 4333s or 5m332s.

Your choice; usually we rebid 2.

They both include 5m332. They are also both similar to our relays after 1-1M-1NT-2. Anyway, the continuations are:

Cheapest step = doubleton spade (2 over 1-1-2-2-2)
Next step = 4333 hand (not 4) (2N)
Next step = 5-3-(32) (3)
Next step = 5-3-(32) (3)
Remaining steps = 3-(442) (3-3N)

The mnemonic is basically that 2N, 3, 3 are natural. However, this obviously doesn't quite work in the 1-1-1-1N-2-2-2 sequence because we are one step up. Note that in the latter sequence we are very much in the slam range though (because opener must be 21+ and responder 9+ for this auction to happen) so bypassing 3NT sometimes is not that big of a deal.

Thanks. I was forgetting that 1C-1D, 1H could be the 5m332.

Next question...if responder has a 6C322 of maybe 6 or 7 hcps just shy of wanting to commit to game, does he respond 1S and treat the hand as a 5C332?

Never mind. They respond 2C to begin with.

So after 1C-1D, 1S-2m/2H...

what are the continuations? What is forcing and invitational and non-forcing? Thanks
