I suck ass at math, but it seems like even i should be able to do this one.

Firstly pot size doesn't matter- i don't think.

13 cards- 2 which double the loss when you hit on the table. X range of winning cards, y is range of cards that you lose to.

So x>y + 4 and y=11-x
so
x> 11-x+4
x>15-x
2x>15
x>7.5
so you need 8 spaces between your cards to bet. And yo always bet the max if your bankroll can stand it.

Edit: there may be some variations- one is that a minimum bet must be made every time or you can pass when ever you want, i don't think this changes your betting strategy any, just you bet the max of gaps 8+ and bet the min all other times. It should still be +ev as long as the min bet isn't a sig % of the pot, but i really couldn't figure that one out.

Also, you should be able to come up with a card counting strategy if only playing with one deck.
