A while ago i made a post in my blog after buying PT3
here. I noticed the exact same thing as you and i gave it more weight than standard pokerEV stuff because its simply divided into two sides that cannot be wrong; non showdown and showdown winnings.
Immediately i tried to adjust and figure out what this could be. After a while i couldn't figure it out so i made another post on leggo
here. Also cross posted on liquidpoker
here. Still, not too much info was gained from this.
A little info about my game: I've been playing for several years although I started off very very badly and about a year and a half professionally. I play like 20/18/4.5 or something while 10-12 tabling and generally log 75k hands a month doing so (this month, even more). When i 4-6 table i play a lot looser naturally (like 30/25/5 to about 28/25/4.5) because i pick up on a lot more situations i can take advantage of and just generally think more in depth about whats going on. I very very rarely tilt. While 4 tabling, i've got an extremely positive non showdown stat.
After having noticed this and keeping in mind my tendency towards a much looser style playing less tables i came to the conclusion that the key was that the games i was playing werent suited for 12 tabling anymore and i'd have to rebalance the number of tables. Either that or my focus/intensity had decreased thus resulting in giving up in more marginal sitatuations due to lack of thinking time.. whatever.
At first i thought its not a totally fair to compare these two styles but it actually is. Its fair because playing looser is my natural style and what i'm comfortable doing it seems 4-6 tabling and while 12 tabling i dont feel i play much different but what i do notice is
i'm folding in spots where i dont have enough time to think about them. This can be because either im not opening preflop or accidentally folding preflop due to autopilot or because im not making the correct decisions postflop due to multitabling etc.
I think after some more adjustments i've managed to at least plug the major leaks for my 12 tabling game which was largely to do with aggression. At my stakes atm (100nl and some 200nl) even if you don't quite connect the two dots in the moment you're playing a hand generally the aggressive route is the best of all. This means, enter the hands you play with a plan and play them aggressively. If you plan to float, float very often. If you plan to call and bluffraise lots of flops, bluff raise very often. Just keep in mind if you're calling to do an action that you actually follow through with your plan otherwise its probably break even or possibly even losing and you just sit there feeling like a passive mother****er.
One thing that was a specific leak in my case was three barreling too little. Generally i overestimated my showdown value in most situations and didn't keep firing even although i know most of the time my opponent has a slightly weaker hand and probably cant call my 3 barrels profitably.
Just gotta find a balance, maybe 8-9 tabling max is most appropriate in my situation but maybe you can only play 2-3 tables and theres nothing wrong with that.
Cheers,
David.
