Bet sizes are made in relation to the size of the pot. Larger bet sizes show polarity in the betting range. This concept means the bettor either has a very strong hand or a bluff.
A smaller bet sizing usually means that the player is betting a wider range for value, not bluffing much. Note that you shouldn’t bet the strength of your specific hand in poker.
Instead, you must decide which hands you could have in your betting range and bet the same amount for all. (You can also split them up between two different bet sizings.)
