I like your overall line (3! pre -> c-bet good board for our range -> double barrel on good turns), but I hate your sizing all throughout. Likewise, I also like a fold pre. Folding is 0EV. 3! and playing the bluff game
CAN be +EV, but could also go south very quickly.
That said, because of your small sizing I think you are inviting a lot of floats from his broadway hands, especially the combos with the A
. I don’t think villain believes you have a K meaning he thinks his A/Q/J outs are probably live if he’s even behind.
Therefore, I’m shrug calling the river here. He’s going to have some flushes, sure, but he’s also going to have random broadways floating to pair up or bluff
’s. His river bet is fairly polarized to bluffs and flushes. Most villains aren’t going to value bet a K on the river here.
