you cant calculate EV based on hot and cold preflop equity, because so much of blind defense considerations are based on postflop scenarios. i cant tell you how handX plays against handsA-G postflop, and certainly noone can tell you how YOU would do with handX against that range. its a pretty easy task to assign hand ranges to an opponent and calculate hot and cold preflop equity. you can do this using pokerstove if you find this information helpful, but in reality its only a minimal utility in coming to blind defense conclusions. because we cannot base postflop scenarios on a mathematical scale, all close situations come down to judgment and nothing else. you should check out the Nigel thread because that pretty much covers the bulk of this. they are interested in combining databases to determine profitability in blind defenses, and that is really the only legitimate way to come to any progress in this matter.
