I know you are trying to stay unbiased but I think it is best if you can hide villain's hole cards haha (From a viewer's perspective).
I usually hide the hole cards, but this time HM3 was giving me a hard time :)
Hi, i like these type of videos!
At what numbe of hands a major leak review will make sense and at what range a micro leak? I can imagine that there is a difference.
How do we know (DYI) if it's a leak? Let's say I have 50k hands and I have been losing in 3-bets pots. Could that be purely by variance?
What do you mean with "every style can win at small and mid stakes"? Do you mean like a VPIP/PFR. of what you do with certain hands post..?
I didn't fully understand the first question, with micro leak do you mean leaks in some specific lines?
It can be variance if you see you're constantly running into sets when you 3barrel overpairs, but it's possible you're overplaying hands on unfavorable runouts or you're not bluffing enough against people that are overfolding and call with a range which is too strong. A coach can address this issue way faster, if you go for the DYI analysis it's always better to isolate some specific patterns where you feel you're losing money (f.ex calling too much, playing for stacks too often) and try to put everything in context.
Every style I mean red line based style and blue line based style. It's also possible to win with different VPIP PFR configurations.
What I mean with that is I can imagine someone has some major leaks, like folding AA. Easy to spot. Not many hands needed. But also very specific minor leaks. I don’t know, ehmmm. Checking the flop 10% too much with a certain range. I can imagine for the latter you need way more hands.
This leak can be harder to spot with a DYI analysis. What you can focus on is missing pure bets/pure checks. These ones are easier to spot and have a meaningful impact on your winrate, especially if they happen in somewhat frequent spots.
Database review or HH review of QQ+ / sets?
We also have some crazy bluffs! :) Database review differs from player to player, some players have leaks in big pots, others in small/medium pots. If a player is leaked in big pots, usually the review will focus mostly on overplayed hands (coolers that shouldn't be coolers), spews and bad calls.
Francesco Lacriola What does part 2 consist of? When I hear "database review" I think you are going to review the actual stats in the database compared to global frequencies. Once the student understands where his stats deviate from global frequencies it is easier for them to filter for certain spots and go through the replayer themselves. Vpip, pfr, 3bet ip / oop, F3B ip/oop, CB FTR, float bets, probe bets, FCB FTR, WWSF etc.
Saulo has a database review and was hoping your review would be similar of going over the actual stats.
RunItTw1ce in part 2 I will analyze high frequency spots (OOP 3bets, IP 3bets, BTN vs BB and BvB single raised pots) and discuss how to approach the specific dynamic analysis. There will be a tendency to focus on bigger pots as the player I'm reviewing tends to make significant mistakes in big pots - we prioritize blunders, then we look for mistakes in high frequency spots, then we look for inaccuracies, depending on the player's skill level.
I'm not a huge fan of stats in general, historically people have been winning at low, mid and even high stakes with completely different stats/tendencies/playstyles. It's much more important to be strong at understanding ranges in play and at hand reading. In particular the stats based approach is flawed in restricted pools (like the ones I and the player from the DB review play in), but I can see its merits for people that play in huge player pools or in anonymous player pools.
Consider that variance is huge and stats, except the highest frequency ones are not very reliable, as you can see higher 4bets/fold to something/missed bluffs because recreational players or exploitative reasons are involved. Consider also that you don't get very often to some check-raise bet shove lines or even triple barrels on specific runouts and even one or two occasions in which you deviate for some kind of reason can have a massive impact on the stat.
This is interesting to me. If you look back at your low stakes period, what VPIP/PFR where most often winners?
And if these matter less, how do we get better at understanding ranges in play and at hand reading?
There is a video from Uri Peleg on youtube for analyzing stats emsterdad that shows the samples needed for the stat to actually mean anything. Francesco is correct about the stats, but I think they are good to know as a baseline and then deviate based on pool's tendency.
I got a lot out if this video. I think one of the most important things for me to hear in this video is not to worry about stats so much as there are different styles that can win and to play to your strengths. So often I try to play in a way that is way outside of what I normally do because I see someone racking up wins with a certain style and I end up hurting myself.
37:05 maybe this is a leak of mine but the flop call seems marginal with no fd or bdfd and we face issues with playability.
Thanks!
It becomes very marginal against 50% pot bets (we can consider just folding there), but with a very small bet you get odds to continue. These hands are tricky to play, as you need to understand on which runouts you have to go to showdown and on which runouts you have to consider turning the hand into a bluff - also having info on different player profiles can make us lean towards one or the other option on specific runouts.
