I think on the actual auction 6h is about our only option but if we rebid 2s it will be interesting to see what pard rebids such as what would 3c or 3d or 2nt show and what do we do over those bids. We could get into a very complicated auction not only in terms of what strain but what level, compared to the straight forward one we actually had.
For instance over 2nt we may rebid 3c.
Are we really that certain we will fully understand the difference between 3d and 2nt compared to what pard will think they will mean?
If you rebid 2S, then partner's next bids would mean:
2NT = diamond length/strength, unsuitable for other contracts
3C = 3-card club support (or high Hx but obviously not here when you have AKQ)
3D = extra values, nothing positional in diamonds, no reason to bid anything else
3H = particularly good hearts (either 7 or something like AKJ109x)
3S = 4-6 majors
others = don't really exist (4D is a splinter for spades, I suppose)
If you started the auction 1H - 2C - 2H - 2S partner will bid 2NT. You have to choose between 3H and 3C over this.
