First of all sorry for my bad English, and sorry for this veeeery long post (It doesn't suppose to be so long, but when I started I couldn't stop :-) )
I'm playing poker for little longer then a year, and I realized one thing. There are days when everything is on your side. Very little, or not at all bad beats, you are playing good, cards likes you... On the other side, there are days when everything is against you, you are playing bad, getting awful cards, and every idiot will hit flush or straight on river, no matter how well you played.
Since I'm playing only sng tournaments (very little mtt, and cash tables not at all) I have excel file where I'm writing every game I played. From those statistics I made a conclusion that I'm not playing so bad like my bankroll shows. Under normal circumstances I have ROI around 20-25% on $5 and $10 sng, but problem is that my bank is not going up, but down (on long period). So analyzing those games I realized that on days when I'm doing bad, I'm loosing much more, then I'm winning on good days. And when I have a bad day, then I'm loosing my discipline too, I'm doing bad moves, pushing, and in one bad day, I'm "killing" 7 days of profit. (Mostly because I'm playing much more games, since I'm finishing faster.)
And, my conclusion is simple: I must find a way to win more on good days, then I will loose on bad days. I was thinking how to do it since I don't have such discipline to stand up from computer when I'm doing bad (If I have it, then this text would be useless ;-) ), and then came on my mind to try to adopt some variation of progressive system from sports betting to poker game (I'm still testing this system, that's why all suggestions and critics are welcome).
This is probably nothing new, but I never heard smb. is playing that way.
So, how the system works? As I said before, I'm playing only sng's and only 6 players sng where 3 players are in the money. I choosed this one because it's much easier to came in the money then on 10 people sng, or at 6 players sng where 2 places are paid. (And you will see that "coming in the money" is crucial for this system). I put my bank on 5%. So, I'm starting a day with a tournament that is 5% of my bank (If my bank is $100, I'm starting with $5 entry). If I come in the money, I'm staying on that level. If I loose before money, I'm going one step down. (if I played $10, I'm going on $5). When I win 2 tournaments in "unbroken chain" coming in the money, I'm going one level up (for example: from $5 to $10). I don't need to win 2 in a row. I'm just not allowed to loose in meantime.
So, for example I'm playing $5 tournaments. One tournament I finish first, I'm staying at that level. Next 3 tournaments I finish 2nd or 3rd (so, in the money), I'm still at the same level. Fifth tournament I finish first again, and then next tournament I'm going one level up; to $10. If I loose any of those tournaments, chain is broken, and next tournament I'm going one level down, and starting a chain again. Every time when I loose I'm going one level down, no matter of previous tournaments. Next day I'm starting again from 5%, no matter how I finished previous day.
As I said before. I'm still testing it, but in few days I doubled my bank (could be a coincidence, I don't say it isnt), but I already realized one thing. I'm playing with much more caution - in positive way; and I'm more concentrated on every hand, because every game is connected. Before, I was playing some bad moves because I was thinking: OK, if I loose this one, I will start the next one, but now when I know that next one will be at lower level (especially if I was in chain of 6-7 tournaments in a row in the money) I care for every move much more.
So, every comment is welcome
