well, i c/f because in a 4way pot, this flop hits the middle of people's ranges, such as QT, KJ, etc, people could also easily be c/c or c/r with a set or two pair as well, and basically the only card that helps you is a 7, so you won't have much fold equity on the turn, A or K will probably be a bad 2barrel card because they could have KJ or J9 which completes their draws.
oh yeah also something to consider, a weak/tight player might also flat TT in position preflop, then c/c flop, c/r turn and if you hit a 7, you'll end up getting your money in bad |
