KPRF comes to power in Russia, 1996.

Let's say Yeltsin botches things more in privatization, wheeling-and-dealing with local elites and the economic crash, and purges the Communists less effectively in 1993. The 1996 Presidential elections come around, and the KPRF winds up winning. Zyuganov is the President and the KPRF is the largest party in the Federal Assembly by more than 2:1 with its nearest rival.

What happens next? From what I understand, the KPRF is a pretty hardliner communist group.

They're pretty old-school, but I doubt they'd do anything much more radical than pander to their base - government employees and the elderly, in the short run.

This is pretty much a lowest point of post-Soviet Russia and oil is still cheap, so victorious Commies wouldn't have a lot of fundamentals to lean on. However, I can imagine immediate full stop on privatization of medium and big enterprises, with several "Yukos"-like affairs settling old scores with oligarchs who lent too much support to Yeltsin's regime.
