Button is a very aggressive regular. Thoughts on all streets?

If you're checking this turn, it should be to CRAI.

Could someone further explain the argument for check/pushing the turn? I'm not disagreeing, I'm just curious to hear a more detailed explanation.

Are you not at all worried about 88, 66, 33, and 45? Is anything hero beats calling?
