stiff;
low-hi doubleton;
low from honor doubleton;
lowest from tripleton;
3rd best from xxxx;
4th best from KQJxx(yes I was the declarer of 3NT and GIB led 4th best from KQJ9x, giving me the 9th trick);
anything else.
Today's lead taught me a new lesson which has never appeared in my dream.
The contract is normal but has no play as cards lie.Any little old lady would know what to lead holding AKQ.
However, holding AKQxxx in one suit, which is the reason GIB doubled first since it's too strong for one level overcall, GIB tried to "cut the link of dummy's suit",and eventully had to ruff with it's natural trump trick.
Kaplan(or AL Roth?) once taught his pd: when God dealt you KQJ, he's asking you to lead it.
GIB, honestly followed the rule, since it didn't have KQJ.
