How to do it
Go over to a site like bjmath.com or get a book with EV tables.
You will have 10 possible hands: T,2 T,3 T,4 ... T,T T,A
with T,T being about 4 times more likely than any other.
The dealer will have 10 possible upcards: 2, 3, 4, ... T, A
with T upcard being about 4 times more likely than any other.
Look up and add these 100 possible expectation numbers together (remembering to multiply the combinations with another T in them by 4)
The sum is a pretty good estimate of your advantage. I think is in the neighborhood of 12% advantage
You have an EV of about .55 on the most common hand: T,T vs T
