1♥ and splinter with N seem normal to me. If partner shows 1KC, then the ♥Q and ♣K, I would probably have to take other things into consideration before I decide what to bid.
Has anyone else read this book? I think it's a great account, for us Americans with our silly major league soccer, of soccer in Europe. I recommend it. http://img718.imageshack.us/img718/744/sangon.gif
I know some (many?) experts who play that here also, but also many who play subsequent doubles are always penalty. I also like first dbl t/o after 1x (1NT) dbl (scramble), but I know fewer who do that.
10+HCP implies no fit. It doesn't say anything about other suits. I personally like the first double by our side following a XX to be takeout, but YMMV.
For a change of pace, I'd like to present BBF with something new: a picture of a cat. I hope you enjoy. http://img145.imageshack.us/img145/9374/52318838.png
