If I actually feel like taking the risk, then of course, I will do that without thinking twice, though with a considerable amount. In most cases, a particular team don't have to do a comeback before bookmakers starts giving massive odds. They just drop the massive odds the moment they are trailing by the two goals, and of course, some bettors would take the risk.

I haven't tried it though because I don't think such risk are worth taking on league games. Maybe a very competitive game like the Champion's league would be the best time to take such risk, because of course, a lot of crazy comebacks happen.
