Harrington's Inflection Points

[nortonmalc]

After reading Harrington's books I figured I would try and put my new wisdom to work. However I ran into two inflection point hands that maybe if I had played my usual way, would have helped me stay alive. I'm looking for opinions of anyone else who is familiar with Harrington's books.

First hand is when there are 4 people left in a single table SnG. Blinds are 100/200. I've got ~1600. There is one stack of ~1200 and two over 4000. I'm first to act with A-10 offsuit. I may have usally raised to 400, but based on the inflection point ideas, i pushed all-in. The two big stacks behind me pushed all-in as well with AKo and posket aces. The pocket aces held up knocking the other two of us out. If I had made my normal raise, I would have gotten out of the way and backed into a third place cash, but as it was, I finished out of the money. Should I have been more careful using the inflection point strategies on the bubble, or was that situation just too much of a fluke?

Another hand is one where I had KQ of spadess on a table of about 6. I had 2200 chips with 200/400 blind in second position. I may have typically raised to $800, but I pushed instead. I had the big stack behind me instacall and he had AJo. Two spades hit on the flop, but otherwise it was blanks for both of us and he eventually took down the pot. Two things may have happened if I had just made my original raise. He could have pushed over the top of me, in which case I probably would have folded. If he didn't, I could have pushed with my flush draw on the flop and might have forced him out with his blanks.

Does anyone else see my logic or was that way I played those hands about the only way to play them?
