Klondike winnable percentage?
I've recently got interested in playing klondike but I'm seeing a conflict between percentage winnable in play and what others are saying are winnable. I've learned that regular is more winnable than the "draw 3" mode. I just play regular and I make use of undo/redo. Anyways, I've seen winnable percentages quoted as low as 80% (in the PGS version) and as high as 91.5%, however after playing game numbers 0 to 482, my success rate has stayed between ranges of 97.52% and 98.37%. Interestingly, I've read that it is actually quite difficult to determine the true winnable percentage, although I thought that a brute force algorithm could surely achieve this? I'm not even confident that the games I've failed on are truly not winnable either, at least in some cases. Some moves that initially appear to be obviously "the way to go" actually prevent success, I found.
