Common question is "Where I can place a bet on Norway II division?" or "Which bookmaker accepts bets on handball?". Since online betting industry is growing every day, those types of questions should not be that common anymore. Bookmakers that do not have large number of betting events on the market will probably go broke. Punters should be able to bet on everything, and there is already enough bookmakers who are offering wide range of sports, leagues and events.
Football
All online bookmakers have in offer all major european leagues. We could not find the bookmaker that offer less then 15 european leagues. English leagues, Scotland Premier, Calcio, Bundes liga, Spain Primera are always on the market as well as almost all westeuropean leagues like Dutch or Portugal First division. When you are looking for bookmaker to open account with, you should definetely ask for more then that. Some bookmakers do not offer easteuropean leagues (Russian, Poland, Slovakia, ...) and it is still big problem to find Second division in Scandinavian leagues. Scandinavian leagues are very important for long summer days without major football games. In one sentence, at least you have to be able to bet on Seria B and National Conference. If not, do not think about that bookmaker.
While betting on football, be carefull of some common mistakes. First of all, look at tradition. It is very important in some leagues. Some teams just can't loose in some matches. Also, be aware of derby matches. Even if you think that Liverpool is class better then Everton, you should know that they are city rivals, and that all players on the field will rather die then loose this game. Save our local derby list and look at it before you place a bet. Perhaps there you will find reasons for such a great odds.
You should also look in the table, especially as the season end is close. Motivation is great factor for european football teams. It is not rare to see top level club being humiliated from someone at the bottom. We use to avoid the games beetwen firt and last on the table.
Be carefull while you are betting on easteuropean games. Since it is wild market, there is lot of mafia clubs all over East Europe so don't be suprised when you see result that noone expected. It can happen in major leagues too, but since there are lot of cameras it couldn't be hidden.
While you are betting on international matches, you should consider national pride and passion for football in some countries, as well as traditionaly bad relationships beetwen countries (Serbia vs Croatia for example is not regular game or Greece vs Turkey, ...). Also, you should read something about supporters of the club, especially when you bet on european cups. Some teams and their supporters are living for european games, since they have boring leagues like Greek clubs, Red Star and Partizan from Serbia, Dinamo and Hajduk from Croatia, and these teams are almost unbeatable at home ground.
Basketball
Since today the only serious basketball league is NBA, you will have problems to find something more on the market. NCAA is very popular at American bookmakers, while it will be hard to find european basketball leagues on the market. Be carefull while you are betting on NBA matches and before you place a bet take a deep look in list of injured and suspended players. Most NBA teams depend a lot on one or two stars, so if he is not playing you should consider bet against that team. In European basketball especially European league you should know that home court is much bigger advantage then home court in NBA, since audiance is not like one in USA. You should check some sites with basketball betting picks
Tennis
All bookmaker have ATP and WTA tennis matches on their list. You should be very carefull when you are betting on tennis matches.
First of all, some players will loose the match on purpose so they could catch another tournament. Look at the stats of that player from last year, also check if the player is already in draw for next week tournament on the other continent. If player, for example had won enough points to cover the earned points from last year and if he have to defend lot of points next week, it is sure that he will loose second or third round match to make anough time to recover for next week matches.
It is possible that some matches are fixed. Even ATP and WTA have some controls regarding this issue. ATP have some aggrement with Betfair and some other online bookmakers to check some matches on which those bookmakers have accept very large bets during last year. Newspapers still don't offer names, but even some top players are in this story. That is why you should be especially carefull while you are betting on big names that are not anymore in top 10.
If you want to bet on ladies, you should consider roumors about their love life. Perhaps it is little bit funny, but lot of examples will cover this story. Look for example at Dokic case. Check also, draw for the tournament
First round matches are the most dangerous for betting. After first round you will be able to see what that player expects from the tournament.
Other sports - Volleyball, Handball, ...
Some bookmakers have all this spots in offer, but it is not that common. You should expect to have these sports in offer during some big euroepean tournaments, or during Olympics.
Cricket, Boxing, NFL, NHL, ...
Those sports are little more regional orientated, so you should expect to be able to place a bet on baseball, NFL and NHL at American bookmakers, and Cricket for example at UK ones. Check some free sports picks site
