I have tried that before on lesser tournaments with players that were not familiar and
based on the odds of the match. It turned out to be a wasted excersize, some
winners but mostly losses. I stick with the familiar players now.
When I am betting on lower tier tournaments I rely on info from pages like
tennis explorer. I check players recent form and especially his proficiency on that particular surface. Then I make bets if I can find value. For instances bookies are basing their odds almost exclusively on player's rank when it comes to players below ATP 200 and you can often find a player ranked 250 who lost all their matches in last 3 months playing against indoor specialist ranked 500. In those situations +5.5 handicap on that indoor specialist is almost free money and ML has lots of value as well. This is drastic example but you can find a couple of badly set odds in early rounds of every small tournaments.
Good tip!
I have been trying something similar for larger tournaments, as im sure almost
al of us have. Looking for big mismatches in rankings and basing that on the
abilities of those players on a given surface, Clay, Grass or hardcourts.
It takes a little bit of research but it is better than accepting the bookies odds.
