Pokersnowie Ranges are developed to Play against perfect opponents. I like the ranges with aggressive and good opponents behind me especially if they have Position on me. Snowie gives u good foundation I believe. Against Whales in the blinds you should loosen up your range lot compared to snowie ranges.

Postflop I have no idea how to rate the strategy of this Software.

anything else ? how is "he" playing postflop ?

Snowie is awsome but you have to play him in 3 ways. First way is to take all the suggestions and play 200 hands at ET or world class graded by snowie. (you will likly be down $ and graded at worldclass) but try and see why

the second way is to play for 0, try and find a fortress way to play 6 handed 600 hands and end up at 0. you will actually be up because u are either growing or dying.

the third way is play it super slow with flopzilla a pluging in ranges and more like a study.
Thats what I do any way. I can consistently beat snoiwe now over 600 hands 6 handed but tilt of in .01/.02.....I think its to slow

Hunter Cichie has a great break down video of snowie and how it uses 66 to bluff a AKJ board and some explanation. go ot google hunter ciche advanced concepte 60 min free video i think its on checkshov.com I believe.....
It is way difernt then pio I haave noticed it recommends 100% bets in MANY spot pio says check. But I dont really beleive in either one of them because in real life you have to adjust so much depending....so they are all good, the more styles you can understand the more u can adjust and the more you can exploit. I like snowie because its a good way to get hands in "deliberate practice" which really in grains things.......I think pio is proboly awsome I have the free version, but to really use it you need to understand it alot, peter clarke looks deep into it and looks at common board types vs ranges and has issues of piovspop, so he breaks it down and uses the info for against people rather then against another pio.
Snowie has definitly helped me. The only problem is most people dont play like snowie, I wish they did.
