Push with this Set?

[akak]

I call here. You guys are narrowing his range too far. He's got a much bigger range then just 98. In fact, it's HUGE.

I've seen people at this level play overpairs exactly this way. I've seen people play bottom two pair this way. I've seen a LOT of people play flush draws this way.

Yah, his most likely holding is 98, but at this level you are losing value by folding here.

A very conservative range would be:

TT+, 77, 22, 98

Against which you are a 60% favorite. That is without taking into account flush draws and two pair hands which he very likely could also have.

Just because you wouldn't play those hands like this doesn't mean you can narrow his range that far.
