Is WA/WB appropriate for this situation?

Either he has a better Ace (maybe 2pr), or he's got a King and thinks we were trying to steal and have nothing (or he likes his King, and is not thinking what we have)

Are both equally likely?

I can see a good case for WB more than WA. KQ is worrying as is any A.

I did shutdown and go for a cheap showdown. It's good to see others taking that type of line also.
