pretty obvious you have an overpair, you are repping a high one, however. the only hand you beat that is calling is 75. so umm.. in this case i could see someone with a better hand calling, and someone with OESD or flush draw having (close) to correct odds calling behind.

so basically you are trying to chase out draws, and if you are confident they are both on one, its a decent play.
