Hello, I´m watching a video from Doug Polk but I have no idea what he is doing there. So the video is about bluff-to-value.

I quote from the video:

Here we gonna take a look at the math and we assume a 2/3 pot bet in all these spots. In all of these spots we gonna bet 2/3 pot.

The spots:
( B = Bet, X = check)
B B B – 55 combos
B X B – 42 combos
X B B – 33 combos
X X B – 140 combos

When you bet 2. Your opponent calls the pot which is 3. Your bet which is 2 and their bet which is 2. So we have 7.
2 / 7 = 0.28 bluff in all of these instances.



I dont know if this screenshot helps but I post it:

Can anyone explain what he is doing?

I mean when I bet 2 then my opponent calls 3 ??? wtf

I think the words came out in the wrong order.
The pot was 3, hero bet 2, and villain faces a call of 2 (not 3, that's just what the pot was before any betting). The final pot will be 7 if he calls. (3 + 2 + 2 = 7)

Yes that makes sense. Thx.
