What Fnord is talking about is all the 20BB-30BB pots. The W$WSF% and non showdown hands are key toa long term winrate. I have spent some time talking to a few people about this problem. Here's an example




the difference in the two graphs is that in the top one (last month)there is a ton of money being lost in non showdown hands. This includes C-bets, flop and turn calls and a ton of preflop calls and 3 bets that end up being folded. I spent a ton of time last month looking for the causes of this and may have made some significant changes for the better even though the second graph (this month) is a shorter sample. i had spent so much time looking for ways to get more value and more money on my big hands, not realizing what some of my aggression and pot building was doing to my bottom line ( pun FTW).

W$WSF% stats are very significant, since having a 35%-40% means we are losing more pots than we win after deciding to put money in pre flop. It is imparitive that we learn to control the losses since most of us know how to win with good/better hands.
