I'm referring specifically to hands like (s)AKQJx (h) Jxx (d)xxx (c) xx or (s) AKQTx (h) Qxx (d) xxx (c)xx that are technically just under the usual requirements for a one bid, but nevertheless have five tricks.
In first or second seat, I would want to open at the one level to give partner a chance to bid. But in third seat, would it be better to open a "weak two" because partner doesn't have opening hand (that would allow a game opposite my holdings) while I fear that fourth seat does?
And is this hand worth opening in fourth seat on the assumption that if the remaining 29 high card points are "evenly" distributed, partner will have the three tricks I need to make the contract?
