Wow, that was an unbelievable passing shot. Poor tie break from Federer otherwise, though. When a match is that close, a few points here and there (even when they don't seem decisive) are crucial. So poor decision making at 30-30 on Seppi's serve, a bad error at 15-30, or something like that can be so costly. The chip and charge might be an Edberg thing, but it's just awful. To continue to do it in key moments is bad decision making, which is the most frustrating thing. If a shot doesn't go in, that's fine. Execution is one thing. But when you actively make the wrong decision over and over, you deserve what's coming to you. Fed was up 3-1 in the tie-break and had a look at a second serve, and went for the chip and charge again for some reason, instead of engaging in a rally and testing Seppi's nerves. Disappointing from someone with so much experience in these situations.
Regardless, in many of these losses, it is Fed's return game that gets exposed the most. When you can't get break points on Seppi's serve, it's a problem.
