20.Incorrect studies?
First Page. 1-20.
Here the first page with a list of studies which are possibly incorrect and most were not yet discovered that way according to the Harold van der Heijden database III 2005.
If in that database in the source of a study an "@" is found, it means that an incorrectness is already found.
The studies shown here are not yet that way.
You are invited to prove me wrong, or correct the study in some way.
Many of them still have beautiful ideas in there!

May be a beautiful draw-study can be made here?

Harold van der Heijden respons in the guestbook:
cook is incorrect: 2…Kf7 3.Kxd7 Rxa2 4.Rxe3 Rd2+ 5.Kc7 a5 6.c6 a4 and now obviously (!) White should promote his pawn: 7.Kc8! Rc2 (7…Kg6 8.c7 Kxg5 9.Rc3 a3 10.Kb7) 8.c7 Rb2 9.Ra3 Rb4 10.Kd7 Rd4+ 11.Kc6 Rc4+ 12.Kd6 wins (White threatens Rxa4).
My opinion has not changed: After 8.c7 Black plays Kg6 9.Rd3 Kxg5 10.Kd7 Kf4 and black is able to draw with his g-pawn coming up.

In the guestbook Harold van der Heijden: cook 2…Bh6 found by S.Hornecker (Post-mail to HH 1-10-2004).
In addition, John Nunn (e-mail to HH, 31-8-2002) spotted 3…Sf6 4.Ke7 and now 4...Bc4! 5.h8Q Sg8+ 6.Ke8 Kd6 and wins wQ!
So this is already in the new Harolds Database III

But what after: 2... Ng3!? 3. Rxg3 Rg1 4. Rh3 h1=Q (Rg3+!?) 5. Rxh1 Rxh1 is a draw?
2. ... Ng3!? Is this a draw?
Black plays f6 and the rook goes to e5, after which white can't stop the black king to e5! The rest is technical!
The last position did not give me an answer on the Nalimov-website....
In the guestbook Harold van der Heijden: Seems to be a draw to me. After 2…Sg3 etc. and Black plays f7-f6 and Re5, and eventually Ke5. But White simply plays Bf3, and only makes K-moves.
Who checks this out?

After 4... Qc2! black threatens Qf2 mate!
5.Rh2? Qc7# of 5. Qxg5 Qxh7 -+
After 4. ... Qc2!
In the guestbook Harold van der Heijden: I’m not fully convinced.
After 4…Qc2 5.Qxg5 Qxh7 6.Qa5+ it’s unclear whether Black can escape from perpetual check, since there is also a stalemate trick: 6…Ke2 7.Qa2+ Kxe3 8.Qf2+ Kd3 9.Qe3+.
So the question is, can black escape the perpetual check after: 9. ... Kc4 or 9. ... Kc2.
Who checks this out?
