For a slow and gentle burn down one side, I catch the other side up with the lighter. Works 95% of the time. Had to do it last night. If it gets more severe like there's tunneling going on alone one side, I do as Bob described and hit the leading edge with a bit of saliva. Sometimes this must be done in combination with catching up the other side with the lighter. It all depends on the cigar sometimes. The smaller ring gauges respond to the spit or lighter technique better and the large ring gauges often need the combo approach. I've never cut the affected end off or chucked it. I'll keep the heat on the back side until it starts behaving as it should.
