Prolly the worst river card imagineable, but whatever...my thinking here is that no real hand is making this bet...Qc is a perfect card to bluff on, but no flush hands he could have make sense as I have the Tc so T9cc, 8Tcc, JTcc etc are out the window, plus a made flush would c/r there all day. This bet is a bluff 110% of the time unless there's history between the players imo...Though raising is the safe play, my rational for just calling was to give him another chance to bluff (which he almost certainly would have if another club hit) and if a 3 hits we go broke...thoughts?
