MSR is can be a recipe race (see Merckx's pattern). If Pogi solves it, he can rinse and repeat until organizers change the course. His remaining three options are a ridiculously long solo (pick anywhere up the road that he can get a split), Cipressa solo, or jump out from the selection from the finish stretch.
But the first 2 options require the relative difference of strength between him and the peloton to be huge in his favour and that's unlikely to last long.
The last one is a possibility but none of the options seems like recipe for a long term success.
