the reason i called was the timing of it he instacalled my bet on flop (imo usually a fl draw) then he instabet turn also i tanked the turn then called on river he shoves after maybe a second i felt like he has to put me on qq,jj ,tt and its a good bluffing spot. i was getting a lil over 2 to 1 and was pretty confident about my read. that said am i still a donk lol?
