I'm sorry, one battle is not going to cut it.
I do this every year..
The case:
Lost the ST2 final.. To Noobster.
Lost in ST3 when checking a cricket score and looked back to find, instead of the full health Skarmory I was expecting, a fainted Celebi. I still dont know how I managed that one..
Lost in ST5 because I was praying for a ch against a Vaporeon using wish protect, with my Rhyperior, which had Swords Dance (I had forgotten the set).
And my ST1 loss I dont remember the details of, but I do remember it was an extremely stupid blunder..
So that leaves my ST4 loss to IPL. This one isnt a choke because there was no reasonable way of knowing before hand, but basically at the time my thinking was "yeah this team is slightly weak to full stall, but seriously, what are the chances IPL will be using that?"
Have a nice day.
