I check behind on that flop like every time.

On the riv i seriously doubt he would bet 1/3 pot with anything u beat on that board. And the fact that if u call and lose you'll only have a 5k stack with 400/800 blinds..i fold.

To be honest it looks like a donk with A3 or A4 or something.

Is it bad that I raise to 4k and just shove this flop?
