Of course, you go on. Partner clearly has very good trumps and probably shortness somewhere. I would want to be in at least 6C but 7C is not out of the question. I would bid 5H to show the heart king and clear intent to go further than 6C. Also, this should promise first round controls in spades and diamonds. Partner should have all the information he needs to bid a grand if he has the right hand such as: S x H AQxx D xx C Axxxxx. Eric Leong
