But first let me summarize my own bidding methods. I was an avid player 55 years ago with "West Coast Standard American" the commonest bidding system. When I started playing again decades later, it was very fortunate that SAYC circa 1990 was almost identical to "West Coast Standard American"circa 1970. (The only real difference was in SF Bay Area we played 3NT and singleton Swiss as strong major-suit raises: Jacoby 2NT was more of a Southern California thing.)
I have noticed that what passes for "SAYC" here is NOT the pure SAYC circa 1990 (is there a webpage with an "updated SAYC"?). For example holding 4-4 in the red suits when partner opens 1♣ we would usually bid 1♦ while most BBO'ers would bid 1♥ or even (relying on Checkback Stayman?) 1NT. I prefer pure SAYC: Keep the bidding low and exchange information. No need to rush and be first to mention NT.
Back in the day, players would avoid opening 1 NT with a 5-card major. I'm happy to open 1NT with a 5-card major, but very unlikely to open 1NT with a 5-4-2-2.
OK. Consider this hand. (I've erased all the names except my own: I assume this is proper etiquette?)
I think the bidding is about "perfect." What do experts think? With red suits reversed, this would be the VERY rare hand where I might open 1NT with a 4-5 but with a diamond suit worth mentioning and a 5-card MAJOR, I won't. When partner rebids 2♠ my hand seemed excellent: few wasted values in Hearts where partner is probably short. Was my 3♠ about right? (We actually made an overtrick!)
What annoyed me is that my expert partner scolded me for not opening 1 NT! I'd stay silent if my partner opened 1NT but it seemed impertinent for him to attempt to impose his prejudice on me. We'd never played together before.
He'd also criticized me on the previous hand; and I'd appreciate expert comments about that also.
Opening a weak-2 with only a 5-bagger and with 4 cards in the other major are BOTH frowned on by conservative bidders, but I said nothing. He, on the other hand was convinced that my bidding was very wrong: If I want to bid my Clubs I should do so immediately, he said -- even before he saw my hand -- rather than passing and then balancing.
I, otoh, worried that an immediate 3♣ would be ambiguous and might get us too high. When it went Pass-Pass however I chose to "balance." The opponents had limited their strength (but likely had enough to venture up to 3♠ down 1) and, anyway if doubled we might escape to 3♥. (FWIW 3♣ did make.) Comments?
