Name fights where you feel a fighter won by having more heart than his opponent. Usually a close fight edged out or turned around by the more gutsy boxer. E.g. arce vs vazquez jr, cotto vs clottey, corrales vs castillo, gatti vs ward 3, hopkins vs pascal 1/2, chavez vs taylor, maidana vs ortiz, ortiz vs berto, marquez vs diaz, vasquez vs marquez etc. :thumbsup
both guys in Khan vs Maidana showed heart, khan in round 10, Maidana in round 1 Khan won on superior skill, Morales out-skilled and out-thought pacquiao thats just my opinion
