I recently found a 2/5 game in my town that runs 11 handed.
The vast majority of my playing has been at 1/2 7 handed.
How much should your range adjust with this many players?
Many more possible match ups 11 handed. For instance
(7 choose 2) = 21 heads up possibilities 7 handed vs:
(11 chose 2) = 55 heads up possibilities 11 handed
(7 choose 3)= 35, 3 way matchups 7 handed
(11 cho0se 3)= 165, 3 way matchups 11 handed
Should I be be playing about 1/4 of the hands I would play 7 handed?
I would play really tight UTG and UTG+1 and slowly loosen up as I get closer to the button, obviously changing my ranges based on opponents. 11 handed sounds miserable crowded though.
I never thought about multiway flop chances the way you just laid out. Interesting.
My wr is significantly lower in 10 handed games. I never would have thought it was a major factor (9 handed is already a ton) but it sure seems to be. I play very tight, seat select at an advanced level, and give more value to pps and less to everything else (besides like high suited cards in lp) basically giving more value to nut making hands and being really tight ep.
Also if it's a possibility of try and talk to the players/dealers/floor about the possibility of reducing the number of players. Depending on the current table count/waitlist it usually makes sense to reduce players + add tables from a floors perspective (doubling rake)
It seems this is a home game, so there is no floor and likely no rake. Nor is overt seat switching going to be condoned.
The difference is going to be much like the differences between 6 max and FR online. As you go to 11 players, you're going to tighten up especially in EP and you're going to bias your LP calls more towards IO hands like 76s instead of KJo.
