I want to know which is the worst hand we can valuebet. To solve this we have to look at villian his river range and then our hand must be a valuebet vs 50% of his strongest range. This is because I will bet pot on river and he must defend 50% vs this.

on river he has 90 combos, he must call with 45 combmo to not make all our blufs +ev.

We van see that we can valuebet KQ vs his river defend range. So KQ is the weakest hand we can valuebet. thoughts?
