Dumbo only bets because he has failed to grasp this and misreads the turn check.
I dont see how uv suddenly judged him because he didnt stick to ABC for one hand....
What if we assume for one minute his opponent is capable of playing more then ABC aswell, he has played it like an ABC player in $1/$2 may play a 10, but these 2 arn't playing a game like that.
And durrr is far from 'Dumbo'
