A single .25 blind is a good idea for a six max cash game at your stakes. Much simpler than .10-.20 IMHO

Shall my highest value colour chips be 10$ or 20$ with the single .25c blind structure ?

shouldn't really be much different. The starting pot is about the same size, so the bet sizes will be similar.

$20, especially since you need to conserve chips. Avoid having one chip worth only 2 of the next chip value (the only exception would be $500 and $1000 chips).

It's different because the chips are different, and the increments between bets is larger. NL pots build exponentially.

3x raise and three callers
10/20 = $2.70
25 = $3.25

PSB on flop and two callers
10/20 = $8.10
25 = $9.75

PSB on turn and one caller
10/20 = $24.30
25 = $29.25

PSB on river and one caller
10/20 = $72.90
25 = $87.75

...

That's a buyin difference for this game. But more importantly, there's less variation with quarters. With dimes, you can bet 50, 60, 70, etc. if you want to do a bit more than 3x, you can do 70c. With quarters, your next jump is $1. Let's compare THOSE numbers...

>3x raise and three callers
10/20 = $3.10
25 = $4.25

PSB on flop and two callers
10/20 = $9.30
25 = $12.75

PSB on turn and one caller
10/20 = $27.90
25 = $38.25

PSB on river and one caller
10/20 = $83.70
25 = $114.75

...

See what I mean? To bet just a *little* bit more preflop makes a significant difference by the end, because there are fewer numbers from which to choose.

That's why I ask what a typical stop loss is for this crew. If it's $80, then 25c is probably fine. But if it's $40 or $60, then 10/20c will keep the game going longer.

A typical stop loss for the crew is 20$ - 30$ but since single .25c structure seems much more simple & fun, I guess we are having a game of blood on Saturday !

As a rule of thumb, in short-handed cash games do I buy-in for more, equal or less ammount compared to what the fish buys-in ?

Yikes. Well, I hope you don't want it to last very long. Have fun!

You should be playing .05/.10 if this is the case. Otherwise, like pfapfap said, it will be a short game.

If you think you have a skill advantage, you want to be the biggest stack at the table. This helps you take maximum advantage of your opponents' post-flop mistakes.

BTW, the above post is what happens when there are no cash games for three hours, heh.

In this case, what value shall I assign to each chip colour ?

yellow=.05 ($2.50)
blue = .25 ($22.50)
white = 1 ($40)
black = 5 ($225)

total bank = $290

To end up with, I am hosting a game consisting of 7 people today (including 2 couples).

From your own experience, would you say we will have an overall better casual time if we stick to a .05c/.10c cash game or would a short-handed SitNGo be more enjoyable to them ? Since most of them are new-comers I am looking forward to them having fun so they come back again later.

Your advice will be a lot appreciated.

Tournaments are always more popular, because everybody has the same at risk.

I'd do a $10 S&G, and even give everybody two "rebuy chips" that they can use if they go bust. No cost for the rebuy, just two more free chances.

You don't even have to run it like a real tournament, just set up the blinds and let them play. Increase them when you feel like it. If they're new, they'll go broke soon enough anyway. If it's getting long, then just say, "Okay, now we're going to double the blinds every ten minutes from here 'til the end!"

Or if you want more structure, play around with http://blindvalet.com/

Have fun!

For people on short budgets, I think tournaments are much better. Nobody likes agonizing over what to do about a 75-cent raise, but in a tournament, the $ are abstracted.

If they're really new, and going all-in too easily, you might make it a rebuy tournament, or at least a 2nd-chance structure. Or limit betting.

Then do a cash game afterwards. Limit cash game is highly recommended.

I think you will find that new folks will enjoy and actully be a little experienced with the T experience more, but add something that gives early bustouts a "second chance" if "having a good time" is a big part of the equation BTW GL
