end game call NLTRN

[arch_angel]

if he has one heart and a five (assuming the other card doesn't pair w/ board) is it right to call here? if not does villan show lower pair, single heart, just the five, or air often enough to make a call correct? I.E. do you think i beat his range? endgame in these is something i'm really trying to work on, any general advice would also be welcome.
