as we are noticing here i am having a lot of trouble playing rivers especially determining whether or not to call bets...i need 29.8 % equity to call

against a range of 99,AdKd,AQs,KTs,QTs,JTs,AQo,KTo i have 29.32% so barely a fold, as you drop aq combos and add sets and other jt/qt's, the ev obv goes down.
