Example 1: 
Thinking opposition opens a wide 
range (we'll say 30% of holdings) and we are on the 
button. We have 3 ways of exploiting this player: 
1. 3-bet for value 
2. 3-bet as a 
bluff 
3. 
call and 
exploit postflop 
We 
don't have many 
reads on this player but we can safely assume that like most players, he is going to 
fold his 
open to 3-bets an exploitably large amount. 
So as an example within the example, lets say our hand is 98s. What is the optimal play in a vaccum? 
Hard to say. Since we think our friend is going to 
fold a ton to 3-bets, it is highly likely that 3-betting is optimal, due to a high amount of preflop 
fold equity. However, 98s is a great hand postflop, and can continue on a very high %age of flops, so we are also certain that its profitable to coldcall with. So do we 3-bet or 
call? Probably 3-bet if we feel that given gameflow he's gonna 
fold 85% of time. 
However, even if he folds a massive amount of the time, the best play for our entire 
range is to 
call. 
In this situation our ranges are subdivided as follows: 
A = {
QQ+ AK}. These are hands we'd be glad to 
stack off with, and should 3-bet for value and get it in. 
B = {55-
JJ, AJ-AQ, KQ, 
suited broadways, 
suited connectors, some 22-44}. These hands aren't comfortable stacking off and are certainly profitable to coldcall. 
C = {22-44, gappers, 
offsuit aces/broadways}. These are hands that are slightly too weak/unplayable to 
call, and we elect to 3-bet these as bluffs/semibluffs. 
D = {the rest}. Have almost no value and we 
fold.
