Stats play a very minor role once you get to midstakes. Most people play differently at different tables so stats is just an average. Someone that opens 15% EP could be opening 25% at this table and 10% at the next table for example which makes it not so relavent. I use HUD only to spot obvious leaks in bad reg's games and prevent me from donating to nits while multi tabling.
While this is certainly true for really good players, I would be pretty surprised, if all stats lose their meaning as soon you make the jump from small to mid stakes. As you said I’m pretty sure the nits play the same game on every table. So do bad to average regs. Don’t get me wrong, I’m not a guy, who thinks stats are the most important thing in poker, far from it, but they help to determine the average range villain goes to the flop with and to spot some leaks in their postflop game. What I believe we should do is to think about these averages and how they correlate to certain table conditions and what we have seen from him and what he has seen from us so far. So in my humble opinion I don’t think that all stats play a minor role, even on mid stakes.
If I have 3k hands of a guy and his river raise percentage is very low, then he almost never is bluff raising the river on any table. If it’s not very low, then you know he is at least capable to bluff raise the river, when the conditions are right. I think this is valuable information.
It’s true, stats only tell you an average, but when a guy has very low raise percentages, he simply can’t be bluffing unless he slow plays most of his big hands. It would be kinda far fetched to believe such a guy all of the sudden starts to bluff raise, because the table conditions are right.
Maybe this video was an exception, but almost every hand was played rather poorly by your villains. In the K9s hand you and FWF think it’s possible villain holds K10 or middle PPs. Only a very bad reg could show up with such hands in that spot. If he is so bad to play these hands oop in 3bet pots, then he certainly isn’t good enough to adapt to table conditions.
Again, you give some guys way too much credit.
I don’t want to start a discussion about stats, but there are some useful ones and some less useful ones. For example the good old PFR isn’t really that useful. You also should not mix up FR, 6max and HU stats and stats from different stakes. Also a lot of people make the mistake to mix up stats from tables, that aren’t full, with stats of tables, on which every seat is occupied. Stats tell you, what the average game plan of a player is. Not more, not less. And when we spot a certain leak in a players average game plan like someone almost never raises the river as bluff, then we don’t need to bluff catch, because it’s unlikely villain has changed his game plan exactly for us.
Another example: We see somebody is 3betting on average 20% in late position. Now we are going to give him hell with any decent hand. Really good players like Blah can act by feel and observation, but it doesn’t hurt to double check your observation with your stats.
