Thank you for posting
Many players have the issues you are having when they transition. Part of it is always lack of volume and part of it may be as indicated by some of your statements not adjusting correctly to live dynamics.
You mention multiway pots after 3 bets this is usually a sizing adjustment that we have to make live.
Live if there is a raise and a call our 3 bet can be 2x 3x 4x 10x pot to get 1 player to call.
When playing live with bluffs we are targeting only a few/ sometimes no players on our table. We have to know they can fold before we try to see if they will fold in any given situation. Of course we always bluff the "they cannot call anything" spots- we will still get called sometimes live.
When playing NOfoldem holdem if we do not make the best hands we do not win.
So when we tighten up we do it by turning part of our 3 bet range into calls and folding 90% of our 3 bet balancing range not by reducing our range to only playing premium hands as AA KK AK versus 4 players is not the nut hand it should be.
When playing live Nofoldem holdem equity realization is more important than absolute hand strength. We need hands that when we miss the flop and are led into we have reason to continue.
A simple example is AQs AJs is a much better hand than AK off in this format. Why? 4-5 way single pair hands seldom win on the river and we are much more likely to stack our V with a flush over flush than we are AK over AX even the worst players know AK beats A5 so we seldom get three streets of value with AK.
As we are not going to be able to pick up small pots very often and our premium hands are going to get cracked more often we want to be in more pots with nut makers so we can make up our equity stacking other players. 63 goes up in value multiway but remember two pair on the flop is not the nuts multiway.
87off suit is a great hand to try to flop a straight with because the other players will stack off with 65 when we do. 87off is better in NOfoldem than 87 suited because you will be over flushed more often by Axs Kxs Qxs Jxs 10xs 9xs all of these combos are possible.
The reverse is true the above flush combos even go way up in value as long as we remember to only play a big pot with what should be the nuts. We know this when holding 96s by the V fearing the flush not wanting to stack off versus a 3 flush board.
Nofoldem holdem plays more like Omaha- 5 way pots the nuts are out there so we do not want to put our stack in with 3rd nuts or TPTK unless we know for sure our V is weaker than that.
So building pots early multiway is not the best way to max equity. When our V will pay off 2x 3x 10x pot on river when we make the nuts we do not have to use a linear approach to betting to get stacks in. This is of course dependent on the strength of the V's range by the river.
The above strategy is in reference to the part of our a range that benefits from getting some folds without hitting. Live we have to discount the effectiveness of getting folds significantly so we do not build pots to leverage a players stack as they do not approach the game that way very often.
The opposite is true when we have the nuts early our V chase big bets early so we bet pot sized bets early so we get more equity by the turn as they will often fold when they miss rivers completely. We play sets this way. We play two way draws this way all high equity hands that we flop.
This is of course how we attack the player dynamics that you described above.
If the table dynamics change we change our strategy with them.
When playing live we play the players tendencies first then the GTO math.
If one player will call when I shove AA for 100BB 50% of the time preflop I will always shove AA.
Hope this helps
