How about other lies that you uses because you can't admit to yourself that you've actually lost because it's a sign of weakness?
One can literally chose different reasons to lie inorder to cover up their loses but I don't find myself doing that knowing fully well I don't have any reasons to lie to a loved one. whenever i counter loses it seems to me as an opportunity to withdraw back from my activity, cause every loses is an opportunity to learn and restrategise.
