[Retros] Proofgames by Heinonen

[Olli Heimo]

In the latest Suomen Tehtäväniekat 3/2010 there were three proof games by Unto Heinonen. The first one is very good. k2qr1n1/pbP1nppp/5p2/p1p4r/2K5/2P1b3/P4PPP/RNBQ1BNR. Proof game in 24.5 moves 14+15. After some thinking all moves are clear and you must only arrange them in proper order.
 The second SPG 20.5 is easily cooked, even computer solves it very quickly in 20.0 moves with several duals. Unto has published a lot good problems and a lot cooked ones. Perhaps he is unable to use computer though I know that he has got as a present very powerful machines. I must write to Unto about it, I have stamps enough. I hope that some day Unto will get a phone or email-address. 
  Yesterday I saw in PDB that Unto's P0006565 has been cooked. Has this cook been known for a long time and should I mention it too. I see that Paul, (what is his last name), has succeeded to cook it by Euclide giving to the computer the position after 27 moves of the intention. From the pages of The Problemist I read: "R244v - Unto Heinonen
The Problemist, Nov. 1995
(Corrected version given in The Problemist, Mar. 1996)" But in Mar. 1996 there is no correction at least on The Problemist pages. This is important to me because I remember that I have been involved in some phases of the composing process.
The third Untos's proof game in Suomen Tehtäväniekat was a dedication problem showing letter symbols and it is not interesting. Olli.
