March advanced tactical probs for Grandmasters only! (Problems)

Yep,
After Siegrun complained that he thought the Intermediate was more difficult than the Advanced I decided to 'turn the screw' a bit more on the latter!
I think the basic idea of the Hellers Colias game - to play Rxe7 and then fork two pieces with Qa3 - is pretty straightforward, it was quite tough to see Black's neat resource with ...h6 and Qxf1+ (although I suppose Hellers did as he is a strong GM), but is the 6 Nxd4 move really that hard to find? The black king is wide open.
In the Wolf-Spielmann game, after the 3rd move alternative sequence starting with 3. Kf1 (which is clearly superior for White than the line he actually played) and ending with 5.Bc4, Black has several moves that leave him clearly on top, for instance (5. Bc4) 5... Ba4 6. Rd8 Qg1+ 7. Ke2 Qe1+ 8. Kxf3 Bc6+! and if 9 Qxc6? Qh1+.
The Schilman-Feldmus was easy once you see the beautiful idea behind the first move - if Black takes the knight there is mate in six and it is very 'linear'.
If subscribers find the advanced too difficult I can wind them down again, any thoughts?
