The only time I've ever called an open push was when I had aces. He had QQ. 25NL donk just handed over his entire bigstack to me.

There's all sorts of reasons why people open push. Sometimes they're maniacs late for work and just wanna go out with a bang on 64s. Sometimes they're holding AA/KK and feel the best way to get value is an open push.

Without a good read (3 open pushes in a row is a good one) you're just gambling...
