Do you call heads up in this situation?

[Jonathan]

Why do you both think this is an easy fold?
What hands do you put him on?

For example, if opponent is pushing with 66, 55, 44, 33, 22,
A6, A5, A4, A3, A2, K6......etc. then its an easy call.

The open push, is very close. But if you assume that
opponent has loose calling standards, then SNGPT shows this
to be a marginal push.

I'm really surprised that both of you think this is such
an easy fold. Explain please.

Thanks,
Jonathan
