Funny , I have been looking at this in the french open and there is a lot of opportunity especially in like you say the early sets.. You don't need to look for an upset just someone who will put up some resistance. Even today,Andy Murray today started at 1.38 but went up to > 2.. He seems to take his time breaking down his opponents so there are gaps there. Best thing about the strategy of really low odds is the low liability means you have some good value and lower risk.
the thing to be wary of when trading tennis, is injuries. which makes it important to not have big liabilities at stake, a sudden injury can see the price rapidly drop or rise, no matter what the score may be, turning a good value position into a losing one. at least in team games, injured players can be replaced, but tennis can be dangerous in that respect.
Solid advice as usual Peter. Tennis is a new market for me. Do your trading courses cover particular sports or just focus on developing general trading behaviour?
A bit of both. There are a lot of things people miss when trading so it's important to cover those things, but also each sport has specific characteristics.
