Did you see Lee Jones' thing on pushing? It has a calculation that's easy enough to do in your head. I extrapolated it a bit, so it could applied to more than just 7xBB, which is all he covered, to come up with this formula: 19 + Effective Stack/BB = Power number. In your case, 19 + 10 = 29.

To calculate your Power number, take 2 times the value for higher card, add the smaller, and add 2 for being suited, to get 13 + 13 + 2 + 2 = 30. So it's just barely a push.

On the call side, you take 23 + Effective stack/BB to get 33. His hand is 13 + 13 + 6 + 2 = 34. So it's just barely a call.

You can get more information on this by looking at the thread that talks about his push strategy (he did it with someone else whose name I don't recall). Looking at the pattern of his numbers, I came up with push if your power number >= 19 + Stack/BB and call if >= 23 + Stack/BB. You can't make a mistake by pushing, as it doesn't matter what your opponent will call with. However, the best calling strategy is assuming your opponent is playing the best pushing strategy, which of course few will be.

If you look at the Two + Two Internet Magazine article this mongth on pushing in the blinds, you can sum up pushing on the BB like this:
a)Any pair
b)Any two with both 7 or higher
c)Any two 5 or higher, if both suited
d)Any Ace or King
e)Any Ace, King, Queen or Jace, if suited.

This doesn't match the chart exactly, but it's close. This strategy is more aggressive then Jones'. For example, using Jones' rule, 56 suited = 6 + 6 + 5 + 2 = 19, which is far less than the 29 needed, but the chart in the article shows this hand should be pushed.

I like the Jones method because it's easy enough to calculate in a few seconds, so you can use it while actually playing. I'm plaing around with trying to come up with a generalized formula for other positions, like on the button or before, something like add 4 for each position. So if Stack/BB = 10, and you're one off the button, you push with 19 + 10 + 4 + 4 = 37, which is hands like KJo, K9s, and A7o.

It seems to me using the Jones formula, you can be a bit more aggressive than it suggests when pushing, but should be more conservative when defending, unless you know your opponent will push at close to or higher than the optimal frequency.
