How to balance between the contradictory objectives of protection and value.
In a situation where i have strong but not a very strong hand and board is very dynamic
The situation can shift quite a lot in T and River

How to not bet too large and make opponents range too narrow and strong, where you are only beat if he calls
or not bet too small and give him the opportunity to see another card at a very reasonable price.

I feel like between a rock and a hard place,
where if you bet smallish and get outdrawn, you take the lesson that u should have bet larger
and if you bet large and get called by hands which beat you, you take the lesson that u should have bet smaller

For example
Hero has 7s6c
Board [F] 7h 6s 3h
a situation where hero wants value but situation can change fairly easily in future streets

I have not mentioned any ranges, didn't think its required for this query.
