I was called by a K10 and he took the pot down.

Please ctiticize my play and my line of thinking so that I can learn from you all. This is one of my first posts so please be gentle with me.

Preflop I raise 3XBB, my standard but perhaps I should have raised higher at early rounds.

On the flop I bet a little over half the pot. This is where I think I made my mistake. Now I don't want to be results oriented but I think he would have called a pot sized bet anyway.

On the turn, I made a newbiew mistake. I didn't know what to do so I pushed. I knew someone outdrew me becasue thats a scarey card with 2 flop callers. Yet, I still pushed (Badddd Leak). I guess I didnt plan on folding with the flush draw as well so I just threw it all in myself.

Was this played horrible? What do you do different?

Cheers
