johnny,

Thought I'd take this opportunity to bring up a 'betting' strategy that was shared by a long time sheet player.
Frank D. has mentioned this strategy previously and might choose to elaborate.
And while I mention Frank---VERY nice simple play!!

As I looked back at your analysis, you chose to make a play against Keen Ice. You chose a key of #7
You also chose the correct contenders. 1,3,4,5 and 8.
You rated the 3 & 4 as "A" contenders. (also correct)
Your hypothetical bet was WP on the key #7 and exacta boxes with the contenders.

What if you were to redeploy the place $$.
The exacta box covers the place money.

Use the place money to create a triple with your key horse for third. i.e
A horses 3 and 4 over 13458 with the 7 for 3rd.
Then, a super bet with the 34/14358/13458/7

The tri cost $8 per $1 unit and the
The super cost $2.40 for a 10 cent unit.

It is a cheap hedge in the event your key horse runs 3rd or 4th. This is primarily recommended when you are keying a long shot.as your key.

In this case, the 10 cent super returned about $70.

This play is somewhat 'conviction' dependent and definitely 'odds' dependent.

Nice analysis and best of luck.
