Folding equity? Whats that?

Gonna post a few hands which may be interesting just due to the fact my opponents are unknowns, new to the table.

i dont understand the push. You want more money from villan dont you? And only hand here that is going to call you has your hand beat.

Do you think villian may fold a weak two pair is too optimistic?

Yes, he min-raises to commit his stack on the flop he's goin the rest of the way.
