Sorry you posted the results before I could get my 2 cents in, but here goes anyway.
First, there seems to be a lingering difference of opinion re: 6-Max auto-rate rules. I get mine here:
6-Max Link which makes this guy tight. The difference is one of starting hand selection. So what kind of hand range can call your flop bet?
The last point that continues to fascinate me is what I refer to as the "Pussy Rule" which says this is a clear fold. Fold here, and fold to the previous overbet where you paid him off.
