You don't work out how big a dog you are by just counting the combinations you beat and don't beat. You average your win% versus each hand, weighting by number of combinations.
For this hand this works like this:
KK v AKs: 65.9%, 2 combinations
KK v AA: 18.1%, 6 combinations
KK v KK: 50%, 1 combination
((65.9 * 2) + (18.1 * 6) + (50))/9 = 32.3%
So your KK wins 32.3%, i.e. a 2 to 1 dog. If you can learn to think in percentages instead of odds, it makes the maths a lot easier.
Also even though when you're against KK it's neutral EV, you can't leave it out of the calculation. Imagine if you knew that out of 1000 times he was going to have AA once and KK 999 times. You can't just disregard all the KKs and say that you're a 4 to 1 dog there. You have to include all the KKs which puts you close to 50%.
