What happens when the stake is halved though, do the bookies keep the other half for themselves?

the stake isnt halved, the odds are halved
you get your stake back and half the winnings you would get for an outright win

Sadly your wrong...

The stake is halved not the odds, as it works in the bookies favour and yes Andym, the bookies keep the other half too.

So for example.. £20 at 4/1, which dead heats.

At half stake you get £10 at 4/1 = £50

At half odds you get £20 at 2/1 = £60

Hence the bookmakers use the half stake rule as it is in their favour along with many other rules...

Spot on.

I use the returns calcs to work out the returns as they can account for a DH or R4

Galway 19:00 Mount Helicon 20/1 E/W Ballyhaunis 14/1 E/W

Had been waiting for Mount Helicon to run for a while then bloody missed it just come 2nd at 6/1 in its first race for 7 months hopefully will come on from that only 5yo and came 4th in French G2 and G3 races.

Ballyhaunis hadn't race for even longer when finish 9 lengths behind Bay Willow who boosted the form yesterday.

I'm going to Beverley races tomorrow, so who's got a few tips?

Bloke I work with drinks with the head honcho for ladcrooks. He came in.this morning with a tip he was given over the weekend. Dubai glory Ithink it was called. 1st race its in dunno price etc but u might want to give it a look.

Does anyone else expect not to see Workforce run again?

The Derby has obviously taken a lot out of him, as with a majority of other horses. Another bad run would knock his stud value down even further and, unless he wins a top all age race, it will hit his reputation badly.

Not as if Khalid Abdulla is short of good racehorses either.

Mount Helicon would be a cracking bet, but not off top weight for me.

Foooking hell 2nd and maybe 3rd Ballyhaunis smashed into 11/2!
