In December of 2019, after taking a long break from composing proof games, I attempted a challenging task in that genre that elaborates on what’s called the Pronkin theme. In this paradoxical idea, at the final position of a proof game, a piece seemingly on its home square turns out to be a promoted unit, replacing the original piece that was captured at some point. A game may contain multiple instances of such deceptive play, with four Pronkin impostors being the most that have been achieved (see a great example in the Walkabout of 30 Aug. 2014). Another way to intensify the theme involves setting up more than one solution (or twins), where each part requires a different home-square unit to be the impostor. Since multi-phase proof games are not simple to construct even with basic themes, those that demonstrate this type of changed Pronkin piece are uncommon and normally two-part affairs. Take for example the eponymous first-prize winner (No.141) by Dmitry Pronkin himself. I wondered if it was possible to extend this idea to three phases, showing a different type of promoted piece each time. And indeed, what about four phases – wouldn’t it be great to combine a four-fold change of Pronkin with the Allumwandlung theme!?
