ok wrong use of "cold". sorry.
What is the "std" treatment in such cases? Partner did not pass 2S hence has something to say. System has essentially restricted partner from 4C jump. 3H is only possibility. Jumping to 5C who knows with GIBBO who is likely to pass as it does most of the time.

The standard treatment is for 4c and 5c to have better definitions and for partner to follow up sensibly, taking preference to diamonds with equal length, raising to appropriate level depending on simulating appropriate hands, and given sensible HCP /distribution ranges for 4c/5c.
I'm perfectly on board with fixing those. Changing it to 3c forcing because double promises a rebid, I am not.
I don't know that there even is a std for how strong 4c is and whether it is forcing or not. It's a rare auction. I don't remember ever really discussing it with anyone. Partner has shown misfit for you, length/strength in the opponent's suits, and is expecting most of the time to simply pound them. So most of the time it's going to be better to double them then bid on. Here, 6d happens to make, but only because both partner comes up with exactly the right filler cards (ace of spades rather than ace of hearts, q of clubs rather than another card in the majors, DK), AND LHO happens to be offshape Michaels. Missing these high cards and not big fit from partner, you need Michaels bidder to be like 5512/5530/5521 with stiff CA, with 5521/5503 usually going to be in trouble.
So I don't know that's it right to bid on even with the 6-5. You get 500 here. If partner had more in majors you might get even more AND your minor game/slam doesn't make.
