Tennis trick - Injured player retiring after first set completed

Hello guys, today i would like to talk about a situation that we can take advantage. It happens when there is a possibility of one player retiring in the end of the first set. In this case we can back the other player with an additional stake expecting for a retirement. If he doesnt retire we can lose one or two ticks or sometimes win one or two depends on the market and if the market has a decent liquidity, and in the best cases you can win more then 20 ticks. I already won more then 20 ticks more then one time just covering the possibility of one player retiring. Notice that this doesn't happen everyday, so, you will have to wait  a lot of time for one situation like this.
