Soccer Strategy-Goals Under/Over 2,5 selection

This strategy is based only on statatistics.How many goals both teams scores and concedes.To do that we take first home teams average of goals scored and conceded at home.Secondly we take away teams average of goals scored and conceded in away matches.
Home team (HT),for example scores 2,2 and concedes 0,96 goals per game.That makes total 3,16 (2,2+0,96) goals per game.
Away team (AT),for example scores 1,3 and concedes 0,75 goals per game.That makes total 2,05 (1,3+0,75) goals per game.
Now we see that HT average of goals in one match is 3,16 and AT average of goals in one match is 2,05.That gives us 2,605 goals between these teams.
This tells that this game can go either way - no bet.
If total average is more than 2,8-2,9 or more it should be an over bet.
If total average is less than 2,3-2,2 or smaller it should be an under bet.
Of course this is not a rule,it simply gives us some point of view to go forward.
To us this system is also good to check injuris and suspensions!There may be some missings in teams etc.

Martingale

I will start this blog whit probably most famous betting system of all time-Martingale.It can be used in every gambling activity where odds are at least equal.All you need to do is bet some certain event and keep betting untill you win,doubleing your stake every time.After winning a bet start from the beginning.Problem whit this system is that it needs big bettingbank.For example:Let`s say the bettingbank is 1000 units and you will start betting whit only 1%>10 units,odds are 2,00.
First bet 10 units
If bet is lost.Next bet 20 units
If bet is lost.Next bet 40 units
If bet is lost.Next bet 80 units
If bet is lost.Next bet 160 units
If bet is lost.Next bet 320 units
If bet is lost.Next bet 640 units
If bet is lost.Next bet 1280 units
As you can see,if your first 7 bets lose then you don`t have money for next bet and that means your broke.Of course you can start for example whit 10000 units first bet 10 units,but casinos know that to and therefore is there table limits.Whit that big bettingbank you can bet on on-line bookmakers.If some bookmakers have limits then you can allways bet 3-4 bookmakers at same time and same event.Probably in football is best betting opportunity >draw,odds are allways around 3,00 and thats is much better than red/black at blackjack table.But betting whit martingale an draw in football is minuses to.For example;if you betting on one team and draw then you have to wait a week to bet again and that is lot´s of time.Another minus is that sometimes teams play whitout a draw very long time and if you have bad luck and you have choosen this team then you end up broke.
IN my opinion this is good system ,but to risky.You will be betting whit all your money to win 1% (example above) and that is to risky.But if you feel that you can win that way,then GOOD LUCK.
