You are right, it wasn't the intention, but the writing was on the wall: Pog vs. Vingo, gap getting smaller and still 10K to go. Smart decision.I know it probably wasn't the intention - that Pinot was indeed going for the stage win - but I quite like how it looked a little like FDJ was doing a mini version of the "send riders ahead" tactic.
Gaudu attacked Quintana, a bit later he caught up with Madouas, then Madouas got dropped, and a bit later Gaudu caught up with Pinot.
