Two points, Biglines:

1. Strong, confident, aggressive, I'm-up-3-BI play can very easily slip into Hyper-SPEWTARD, agro-in-the-toilet play. Finding that break-point has been the best improvement to my game this month.

2. Solid, aggressive, fold-the-crap poker while on a cooler can very easily turn into weak-tight SPEW. Still searching for that break-point.

Spoon has it right. Mindset is key. The individual poker hands don't look all that different between strong +EV poker and SPEW, imo. It's how those hands fit with table conditions, stacks, position and so forth that really makes us profitable.
