Vooruit dan: nog één keer Dijkhuizen-Prins (3)

Voor de echte die-hards, waartoe beide betrokkenen in ieder geval gerekend kunnen worden, nogmaals bovenstaande stelling (Dijkhuizen-Prins, clubcompetitie, 1/10/2014). Ik heb een en ander ook (afwisseling van spijs doet eten) ter uitwerking voorgelegd aan schaak-programma Arena.  Een '15 zetten-analyse':
