if there is a odds-on favourite then i would bank it and put the others in some multiples (trifectas).

i take note of those horses that have been plunged inside the last 15mins of betting, even those that have been plunged but closed at around $20 prooves to be worthwhile place bets.

other than that i would bet for the win on multiple horses. if the favourite was paying $3.80 then it'll allow me to place 3 $1 win bets. Lets say I put win bets on the favourite $3.80 and two other horses $5.60 and $7.10. if any wins well i make a profit. i get three win chances in the race to make a profit. the problem can occur in that the final odds are not calculated in time of jump, so you must be sure that the favourite will not go under $3 in the last moments of betting if you are putting on three $1 win bets.

i like to hedge my bets with a 1*4 combo. if the horse wins it pays well, if it places (second, third) then as long as the place dividend is $1.20 then i make a profit still. $1.30 * $4 = $5.20, profit of at least 20 cents.
