Villain is 27/27 and folding 50% to 3bet over small sample. Pre is a mix strategy i decide to 3bet it here. Flop is interesting i think it is very good for my range as i have most AK here and top sets here. Villain has a lot of two pairs as well. I also have a lot of hands i need to check so put this in my Checking range. on turn i could check again but bet mostly for protection here. On river, his sizing is bad i think as he indicates that he will bet often on this board here which i im not sure about. I dont block missed FD's and do block some kings like KJ and K9s so i call to bluff catch. Only need to be good little more than 1 out of 4 times for the call to break even. thoughts? and what do we do vs more polarizing sizing like overbet?
