MrQ: Should East raise it to 4♠ preemptively? Wouldn’t S bid to 5♦ anyway? You guys doubled 4♠, didn’t bid 5♦.
Guru: Yes, East should bid 4♠ every time when West bids 3♠ and that is not necessarily preemptive since there is a TEN card fit. And yes, South should, and would, bid 5♦ and then East should bid 5♠. We guys stuffed up badly when North did not give South a positive response playing PRECISION after a 1♣ opening, and then North for some reason DOUBLED 4♠. What was South to do?
