Wie schlage ich ein Schachprogramm?

I happened to pick up the 1/2016 KARL chess magazine in Frankfurt Airport today (only one bookshop seems to have chess magazines anymore, and I missed it in my April travels). On pages 50-53 there is an article by Moiseenko about human/computer matches, the latter playing on iPads.

There is Zimmermann (the main guy behind these) against Stockfish 3 (iPad) 15-minute game from Aug 2013, then SF5-Moiseenko from Aug 2014 (no hardware given), Zimmermann (2289) vs Shredder iPad, one hour game from Sep 2013, Moiseenko-Shredder (iPad) from Mar 2014 (two games). I will say more when I digest the German text.

The article starts by giving a couple of classic anti-computer positions (poor evaluations on blocked boards), then it gets into Zimmermann's anti-computer strategy, before the "main event", the Moiseenko-Shredder (iPad) match from March 2014. This was played at 15m+5s at the Chess Tigers Training Center in Bad Soden. Moiseenko had White in all 4 games, two with 1. e4 e5 and two with 1. e4 e6. He says "Ich verlor am Ende knapp und ungl├╝cklich mit 1,5:2.5." It then gives (with moves omitted until move 13) the drawn game, and Moiseenko's win via the "strategy", namely "1. e4 e6 2. d3 d5 3. Nc3! (Ein Anticomputer-Zug. Klare Strategie: 1. Bringe den Rechner aus dem Buch. 2. Provoziere ihn, das Zentrum zu schlie├čen!"

The editor Harry Schaack also tried the anti-computer strategy, and drew at least one blitz game by a board-blocking setup.
