(Hmm. I've seen several unfinished scenarios on this site with PoDs dealing with the Polish-Bolshevik war. I've yet to see one where Poland is not overrun, let alone performs better than in OTL. I'll see if I can find the time to do something about the lack of such timelines during the next few weeks.)
A more successful Poland in the Polish-Soviet war would be an interesting TL as well...
