in b4 lock.

Max value is 1 penny less than the amount you think your opponent will fold for.

A huge overshove on the river is not going to get any other reaction at your level then "oh ok I fold" here.

Also, I'm pretty sure you could have made turn larger to help induce a river crying call if your opponent isn't drawing to a flush/straight, and River you probably don't get anything ever from flush/straight unless opponent is me.. but I'm terrible.
