Hand 1:

-no overwhelming reads on villain, he is running at 30/8/2.4
-is the turn spew? should I just check through/ or bet harder?
-give up on river, or fire again?

Hand 2:

-villain is 36/19/3
-I had just had a hand with him, where I had top pair K with KQ OOP.. and I was check calling (since he had raised PF), and I made a blocking bet on the river, and he raised that bet after going runner runner for the flush
-Is there a better way to play this hand? Lead the turn instead of check calling?
-after my river lead, I'm pretty committed
