Tyler covers the concept of 1-A and how to make adjustments to the rule when you have blockers.

Nice video, I think seeing actual hands that you played would be a much more helpful than the toy game stuff though. I find that kind of difficult to wrap my head around. Hand histories would be really useful.
thanks

Dont agree. I think it's better to start with a toy game. Real hand example solution are more complicated and its harder to focus on 1 topic. Great video Tayler. It's been a while since sb did a theory vid like this.

Great video but highly agree with Taiga; - it's a great starter but it is much more valuable imo to see a confirmed good winning player apply this in game and in which spots this plays out exactly.

OVERALL I feel that most often taking in blockerconsiderations usually is kind of the "tip the scales" data point in close spots..
In most spots against usual fields I usually assume that looking at these concepts and looking for blockers can very quickly lead to over(bluffing/calling/folding) if u become blind for the more obvious exploitable tells and signs the situations gives you.

For me this is kind of being torn apart between "okay Ima be GTO here" and Nicks (Howard) approach of just confronting the 'reality of the frequencies of the pool'...
Always interesting to think about it; the practical application in my very humble opinion is limited often.

Thanks for your post! I agree that if we have clear exploitative reads then exploiting is more profitable . However most of the time stats are ambiguous so this helps me order my bluffs in terms of profitability.

great vid.
do the bluffs that are bluff catchers make more cuz opponent will overfold due to us not having enuf bluffs? therefore, they do yield some of the pot instead of being 0ev?

Tyler Forrester 8 years, 1 month ago

Yes exactly FBB. Its because we don't have enough bluffs so our opponents overfold enough to make a bluffcatcher breakeven as a bluff and this moves all of our regular bluffs positive.

Great vid. In the second example, why isnt the bettor betting all his AA and KK but checking some frequency?

Tyler Forrester 8 years, 1 month ago

88 is a bluffcatcher, so our opponent will bet in position to gain value against this hand. Since our opponent is betting sometimes in position, checking AA-QQ a small amount will lower the number of bets our opponent can make which lowers his maximum EV, therefore its GTO in this situation to check some (few) nut combos.

Would love to see another video that expands on your last and imo most important part of his video. tailoring our best sizing to 2x to make a bad bluff into a good bluff.

Hey Tyler - great video! Regarding the second example (too few bluffs), two questions: (1) why does the bettor only bet 90% of his value hands? (2) it looks like he bets 40% of his medium-strength hand (88) - is there a way to calculate that by hand (the way you can calculate alpha or optimal bluff frequency as the pot odds offered, in a nuts vs. air toy game)?

Tyler Forrester 8 years ago

1) It turns out that checking is equal value at that betsize b/c I actually value bet JJ -99 and turn 77 into a bluff when he checks to me. This forces him to check some small fraction of nut hands to keep me from betting JJ-99 more often

2) Yes, you want to bet the fraction 88 and 66 that balances betting AA,KK, QQ and makes 99-JJ indifferent to calling a bet.
This would be optimal bluff frequency with pot odds offered. Note: There is slight discrepancy due to OOP checking AA-QQ here 10% of the time.

John Jernigan 8 years ago

Re: #1, I suppose this illustrates another difference between this example and the pure nuts vs. air toy game. In the latter, position is irrelevant yes? But here it looks like because OOP doesn't have a purely polarized range, he now has to protect his checkback range (because in a pure nuts/air game IP would never bet JJ-99 because he's only called by worse). Is that the right way to think about it?

Tyler Forrester 8 years ago

Exactly John, we're starting to get action that resembles real poker with mixed strategies that protect against exploitation.

24:50. What makes the K, Q, and 8 the best bluffs besides it's paired with the Ad. What makes them superior the AdJo?? Is it just an arbitrary genesis into the bluffing range to have the proper ratio? What calling range are you ascribing to "him?"

TexasFoldUmmm 6 years, 8 months ago

You know what? That makes a ton of sense. I was watching you all night and drinking -- which I rarely do (drinking) -- while my girlfriend was showing me pictures of turkeys in Casper, Wyoming. She thought, you were from Alabama, too? I was like this dude is way too smart to be from here.

I was one rewind and one less beer away from saving you a question in this thread.

Hi Tyler, at 34:26, how is our calling frequency influenced when villain villian holds a blocker to our calling and folding range, at 34:26. Can you elaborate on how have you come to the number 92.5, and the thought process behind.

Also do solvers these days take into account how might villains bluffing hands influence their own range, and adjust the calling frequency accordingly?
Thanks for this exceptional video.
