TAB Betting Blog: Giants, Pies are Round 12 certainties

Here are TAB.com.au's best betting options for the upcoming round of AFL.

Best bets

Head to head: GWS to defeat Adelaide at $1.73

Greater Western Sydney have been heavily backed with TAB to win this match despite it being at Adelaide Oval.

GWS holds 64 percent of all money wagered on the head-to-head market.

The Giants have won their past two clashes against Adelaide by an average of 20 points. They're second on the AFL ladder and every win counts as we edge closer to September with a top four spot up for grabs.

The Crows would be their most significant scalp since knocking off Geelong in Round 4.

Half/Full double: Collingwood/Collingwood at $1.65

A controversial four-point loss to Fremantle last week ended a seven-game hot streak for the Pies.

Collingwood will be looking to bounce back, and why not do it in front of a raucous Queens Birthday crowd before the bye?

Collingwood have won four of their past five games against Melbourne with the average margin in games between the two and 13 points.

With rain expected, back the Pies to rise to the occasion. The Dees have been favourites entering the past two contests against Buckley's brigade however have fallen short terribly on both occasions. A 16-point loss in the last round of 2017 cost them a Finals spot, while this time last year it was a 42-point drubbing.

One TAB punter is full of confidence, having placed $12,000 on the Pies to beat Melbourne on Monday.

If past encounters are anything to go by Collingwood start well and finish better.

Value bets

Special: Melbourne to lead at the end of any quarter and lose at $3

Melbourne have struggled to find the form that saw them make it all the way to a preliminary final last year, however, they have been very competitive the past few rounds and were unable to pinch a last-gasp win against the Crows last week.

On five occasions this year alone, the Dees have been leading at the end of a quarter before going on to lose.

TAB punters believe this clash could be close!

Total score Over/Under: Under 157.5 points at $1.90 Sydney vs. West Coast

The past six encounters between these two have remained low-scoring affairs with an average of 155 points.

TAB punters seem split as the Over/Under market is currently divided at 50/50.

Star Swans forward Lance Franklin kicked eight goals and one behind in Sydney's two wins over the Eagles last year and could be the decisive factor if a high or low score is to be achieved.

Margin: Geelong to defeat Richmond by 1-39 points at $2.10
