This is an $11 ACR MTT. 

One of those spots where I'm not sure if my basic intentions are sound, and my execution is off. Or if I'm just lighting money on fire :).

1) Need to up my sizing on the flop? Is donking a smaller size going to be better when repping a thinner range, for example on paired boards?

2) The turn is pretty poorly played. That being said, if villains have overpairs and draws in their range, I thought this would maximize value. I'd also be capable of doing this with draws myself. Obviously betting more on the flop would have made jamming turn a bit smoother.
