playing any sit and go format where you are paying more then 10% rake is atrocious. I wouldn't touch it.
Double or nothings are a stable easy way to make money if you know what your doing, but it does take some adapting to and normal poker rules have to be broken.
for example if you have 3400 chips and someone shoves all in for 1950 when blinds are at say 200/400 and you have QQ and put them on a steal attempt, this is still a fold.
I assuming you start with 1500 chips there. your likely to be through anyway and jeopardizing most of your stack is not wise I would only call with AA there.
I once folded AK pre to a second in shove i had 2400 chips the guy shoved for 1100 2400 is still pretty safe and likely to get the money. if i had called and lost i would have only 1300 chips he had 44 it was 55% chance had I called I would of gone from been likely through to likely out. and if I had won the hand I would have gone from been very likely through to an almost certain through. so it was the right fold but amateur plays don't know this (proven by a guy with 2200 chips calling this with q9 off suit
). I turned $200 into $1000 with about 60 hours play doing $5.20 double or nothings on stars so I have a fair idea of double or nothing strategy.
There I was paying only 4% rake per sit and go I always multi tabled played 15 at a time. If i won 8 out of 15 thats only $2 profit due to the $8 payed in rake. but note if I had payed 5.50 i would have lost $2.50 assuming I only won 8 out of 15 of these.
now if the rake had been at 15% like yours is, winning 8 of 15 is now losing me $6.25. of course I had a better record then that and usually won between 9 out of every 15.
Thats a lot higher then most and maybe there was a bit of luck involved but I think things like folding that AK made the difference.
if your micro bank roll then do the $1.10s thats less rake and eventually move up to the $5.20s paying much less rake is important.
There is definitely money to be made from double or nothings like there is from almost all formats of poker but when the rake is to high there is rarely money to be made.
You have to learn double or nothing strat too as well it is very different from cash tables, tournament or sit and go poker.
I think I might write a strategy page on it for people here sometime.
