This is how I played the sequence (Races 2-4)
Race 2
$2 DD 5/1,8
.50c P3 5/1,5,8/1,3
Race 3
$20 win #8 Humor 15-1
$2 exbx 1-8
.50c tri 1,8/ALL/1,8
$2 DD 1,5,8/1,3
Race 4
$20 win #3 Litigant 15-1
$2 exbx 1-3
.50c tri 1,3/ALL/1,3
$2 DD 1,3/3,6
Race 4 looks like typical Ochoa subterfuge. Puts Camacho up in the 1 to draw the bettors away from his well-meant entry, #3
Risked $90, -$885 meet
