Alert natural raise to 3?
Last week, I opened 1H and partner raised to 3H. When asked if this had any special meaning, I said it showed a minimum of four hearts and an eight loser hand but was limited to a (probable) maximum of 10HCP because with the same loser count but 11+ points partner would normally prefer a conventional 2NT response.
The opponent complained that I should have alerted because partner's response didn't show the "standard Acol" range of 11-12. Is that true? Do I have to alert this bid because it doesn't show the allegedly "normal" point range for a raise to that level?
