Here is the situation ....I am sitting on the Button with about $500 in front of me with KcKs a few limpers in front of me and i make it 20 to go (it was an action table) small blind flat calls and i get one more caller from UTG+1 flop comes down Js7h3s everyone checks to me and i fire $60. Small blind flat calls and UTG+1 folds. turns is 5s. Small blind bets 140 to me. Small blind has been playing tight for a long time........After thinking for a while I fold since I think she has a flush. Was it a right fold? (Small blind had about 350 to start the hand with)
