It is the lesser of 2BB or 7 chips. So a limit game with 1/2 blinds has a max rake of 4 chips.
Table Starter Rakeback applies to limit also. All 2 and 3 handed play at 6 and 9 seat ring games gets 50% back weekly on Monday. So shorthand limit games of very high stakes still effectively only rake 0.0035 BTC per hand.
Thanks so 7 chip max and yes I know the 50% rakeback .. that works fine .. basically 1.25% and around $.25 max once rakeback is there 2.5% and $.5 at the tables .. FYI, it is a little high in HU play, but not sure why someone would play on HU table just go 6max and sit out if gets to many players.
Stars rake is 2% $.5 so your comparable, but rakeback wins the day. Thanks for the info, just want to make sure I wasn't playing a max 20 chip game.
