This could be an opening bid problem too, but I opened it 1D.
Third seat, They vul - We notvul, BBO ACBL IMP pairs tourney.

AKQ8
QJ64
AKQ106
void

Opponents silent:
1D 1H
4C! 4H
4S 5H
6H

The one time that Exclusion Blackwood came up as The Only Convention to solve a bidding problem, I forgot to use it! I'm shocked at myself!
I decided to bid six anyway because partner did not cue 5C so it became obvious he must have either HA or HK and if I bid six while he holds AK in hearts, he'll raise. Would you agree on 6H? On raise if holds AK hearts?

I looked at the 41 times this hand was played, 14 were in 6H, the rest in games and 1 in 3CX by the other side. The field was bad.

Yes, but in this case GSF is 5, not 5NT.

Partner could hold:

xxx
T9xxx
xx
AKx

or some varient thereof with just enough high cards in clubs (and possibly a pointed-suit jack or 2) to respond in hearts to your 1 opener. You could be off both top hearts.

5 has to mean we have everything but the top two heart honors in this rare sequence.

I think 6H is quite automatic. If I didn't have exclusion here, I might even jump to 6H right after 1H. Now if partner doesn't raise with AK in hearts... well I might be looking for new partner.

The problem with the 5-of-trump bid ( 5H ) here is that Responder is asked:

a) to bid (only) 6H with 2 of the top 3 honors
[ and then you can bid 7H ] or

b ) pass with 0 or 1 [ and you miss slam with 1 ]

And the GSF is not without its problems either ( as stated ) :

a) Yes, Responder bids 7H with 2 of the top 3 but

b ) bids 6H with 0 or 1 [ and not in good shape if 0 ].

- - - - - - - - - - - - - - - - - - - - - -
Exclusion seems to be the best call....

1D - 1H
5C! - 5H ( 2nd step = 1 or 4, excluding A )
6H

I don't think ArtK meant GSF in its purest sense. More like just pass with 0, bid 6 with 1, bid 7 with 2.

You are missing the point.

The sequence:

1 - 1
5

says raise one level for each of the top three honors held.

Very useful for when you have 2 voids.
and the result can be plotted on a graph.

Therefore it is a convention that you must have if you play in the goulash tournaments on BBO.
