I very well may be way off. I havent played LHE in months and months.

Further, any sort of advantage I give up by being a little tight vs blind steals I make up by stealing liberally myself. It probably comes out to close to a wash, with the real money being made and lost postflop.

I believe over defending to be a way larger leak than under defending.

Blind play was never a place I was excellent at, though, so I'll fully concede I may be wrong. I played it very player-dependently. If I noticed you were "quickly raising 50% of my hands in steal situations", I certainly wouldn't play you the same way as I would if you were still only raising 20%. Thats a pretty big assumption to make.

And I'm not going to get in an e-penis waving contest over whose BB winrate is less negative.
