Monkeyinjapan,

'Unders' is a subjective thing.

I look for races where I think the likely favorite can be beaten and in most races favorites are beaten, so why look for and back favorites you think can win and accept their inferior prices when there are plenty of races where the actual winner is more than likely going to be 2nd, 3rd, or 4th. SP fav. That's the easiest way to find good prices .......for this punter anyway.


Chrome,

If a punter backs a good wet tracker on a 'heavy' track and there are say 4 runners in the race who have never run on heavy before [wet track maidens], the punter is betting blind and guessing [and bad luck also if your runner cops a big lump of turf in it's face at speed].
One [or more] of those 4 runners just might be a brilliant wet tracker and even better than the one that has been backed. There is no way the punter can know this until after the race.

If any horse[s] in a race does not have exposed form for the track conditions, the race is a guessing game. Guessing and punting are a good recipe for losing money. There will always be another race, so why bother with slow or heavy tracks where horses are having mud and turf kicked up in their faces at 60ks? Some punting tragics justify it because they just HAVE to have a bet, regardless of conditions.
