[Aisthesis]

True, but you can put an exact percentage on the frequency with which a given hand wins against a random hand heads-up (or, for that matter, against any number of random hands, but the results will be different). I think that's probably the only meaningful way to define the problem (at least the only way I can think of).

Shouldn't the order of the Karlsson-Sklanksy rankings reflect this (even though they're expressed as stack sizes in SB)?
