fwiw, it's a no-brainer to me pre-flop if my stack is a bit smaller or a fair bit bigger - I guess i'm getting too risk adverse by not just shoving with the stack I had (where i'm not in dire need of a double up, but don't really want to commit over half my stack).
Ignoring the individual hand I'm guessing this is the underlying issue, taking some risks when you're not in dire trouble - but not comfortably chipped up, is the way forward maybe?
