what is edge of predicting two aces in next 13 cards slug?

[brighten]

at least we can consider it is TC 8. However, it should have much higher edge than tc 8( less than 4% edge) since Ace 's value. Also, if I play by myself, how many hands should I play to maximize my EV? I have about 50% edge gettign an Ace in my of my hand, 0.5% house edge w/o ACe, and I will face about 37%
house edge if dealer get one of the Ace.

thanks.
