from my experience... a check raise from a passive player @25NL is usually better than TPTK. there are some interesting opinions about this here.... 25NL vs 200NL... C/Ring... draws... sets... etc.

but as you pointed out... this guy C/R a gutshot. is he gonna do that again with some strange draw... THIS DEEP STACKED... especially since you (or someone) called him down and saw his 79. i'm not even sure a maniac 25NL player would this deep stacked.
