Set up this hand in ICMIZER (step 1) as we've explained in the previous section. At this hand history, FGS depth needs to be set to 5 because it's a recommended value for 3 players.

Let's get and interpret the results. Click ❶ ICMIZE to see how the optimal strategy versus opponents who play optimally looks like.

BTN made the raise, and Hero can now fold or go all-in, if he goes all-in, it would be the first all-in, then the player on BB can fold or go all-in, and if he goes all-in, it would be the second all-in, and ICMIZER terms that "call" and marks the range with C symbol. It doesn't mean the regular call, and it means the second all-in. The first all-in is called push in these terms and is marked as P. If the player on BTN all-in too, it would be the third push that ICMIZER terms as "overcall" and marks as O.

1 - the BTN's raising range.

If Hero goes all-in:
2 - the Hero's pushing range;
3 - the BB's calling range after Hero pushed;
4 - the BTN's calling range after Hero pushed and BB folded.

If Hero folds:
5 - the BB's pushing range;
6 - the BTN's calling range after Hero folded, and BB pushed.

As you can see, in the "Main ranges" tab, there are just pushing and calling ranges. If you want to see the BTN's calling range that termed as "overcall", you need to open the "Overcall ranges" tab.

1 - the BTN's raising range;
2 - the Hero's pushing range;
3 - the BB's calling range after Hero pushed;
4 - the BTN's calling range (overcall) after Hero pushed and BB called.
5 - the BTN's calling range after Hero pushed, and BB folded.

We see that the BTN's optimal raising range is 34%, and his calling range (overcall) calculated as 4.2% or 99+,AQs+,AKo. Hero's optimal pushing range calculated as 17% and his profit with QJs push is 0.24% of the prize pool.

Let's have a look at what will change if we assume that the player on BTN has a wider open-raising range as 40% and a very tight overcalling range as JJ+.

At first, we need to edit the BTN's raising range. Open the range editor of the player on BTN, as we've explained in the previous section, and change it to 40%.

Then, we need to edit the BTN's overcalling range. Open the "Overcall ranges" tab, click on BTN's overcalling range with the right mouse button, and change it to JJ+.

So, after you changed the BTN's raising range from 34% to 40% and his overcalling range from 4.2% to JJ+, click on the Hero's pushing range with the left mouse button to find the best response range for Hero on the SB against the BTN's edited raising and overcalling ranges.

Now we see that Hero's best response pushing range calculated as 50%, and his profit with QJs push is 0.45% of the prize pool.

To return ranges to optimal ranges for all players, you need to click on the "Reset locks" button and click on "ICMIZE", as we've explained in the previous section.
