If the jump is above our game level then it is automatically exclusion blackwood. My rule for splinters is that if a non-jump is forcing then a jump is a splinter, one doesn't need to set trump for this. I didn't think that 5C here could ever be natural, but bridge is difiicult without agreements.
Well, I am certainly not sure that 5
♣ here is a jump above our game level, because we have not set trumps. So this goes back to if 4
♣ is "forcing" (I believe after cue-bid it 100% is), would 5
♣ be exclusion blackwood. I go back to rule #1 concerning exclusion blackwood... for me it only applies AFTER a sound trump agreement has been established.
So a jump to 5
♣ would not be exclusion. If one exclused exclusion/splinter for this jump (which I think you have to do), that leaves two possible meaings...I have a lot of clubs -- and am unambigiously settng trumps and inviting slam with a heart control. (I cue-bid hearts first to show this control). I think this is the meaning I would apply. This means a jump to 5
♣ immediately over 2
♥ would deny heart control or at least deny strong slam interest while showing a great club suit (remember doubler might not have all that many clubs).
So you can separate between the jump to 5 clubs and the cue-bid then jump to five clubs. So what would cue-bid, 4
♣ followed by 5
♣ show? The obvious answer is either a hnad with two places to play (say diamonds and clubs, or spades and clubs). I happen to agree the right way to bid this responder hand is to cue-bid 3
♥ and then, cue=bid 4
♥, then bid 5
♣ over 4
♠. If you play it, this FIVE CLUBS would be eclusion for spades, as the second cue-bid, as others have pointed out is clearly agreeing spades, clearly suggesting slam. In fact, I would participate over 4
♥ by cue-bidding five clubs. That will not warm partners heart, looking at his void.
But as HAnnie just pointed out.. bridge is difficult without agreements. It would be reasonable I guess to play all in game forcing situations as "exclusion" but lets examine a differnt auction...
(1D)-DBL-(2D)-3D
Pss-3H - (Pass)-4S
Would this 4S be "exclusion". This in an analagous auction. I would take 3
♦ as alsm try, and 4
♠ as optional.. "partner I was too good just to bid 4
♠ on the fly, ball back into your court. By Hannie rule, 3
♠ would be forcing, so 4
♠ here would be exclusion. I prefer my way. I wonder how many play either of these auctions as exclusion?
