Aside from the obvious factors such as injuries and talent, the most important consideration for handicapping a short tournament like the World Cup is chemistry.

There are always plucky underdogs who find a winning formula and gain momentum during the group stage (think Costa Rica in 2014) and powerhouse countries who implode and crash out of the tournament early (Germany in 2018).

The trick is to identify them and stay on the right side as long as possible.

Starting with Sunday’s opening match between host Qatar and Ecuador, I’ve been handed a $5,000 fantasy bankroll to bet during the World Cup on sides, totals or props.

Until the final is played Dec. 18, expect plenty of plays on Brazil and Denmark, along with several obscure references to Dutch soccer players.

Below are his bets for Monday:

Bankroll: $4,795

Sunday: Lost $100 ($105 pending)

Today: Betting $1,500

Bet 1: $100 on U.S.-Wales Under 2 goals (Even)

Breakdown: This match will go a long way in deciding who advances from Group B along with the favorite England. Neither team can afford a loss, and that should make for a tense affair. These teams played two years ago and it finished 0-0, though several top players for both sides missed out on that match.

Bet 2: $1,400 on Argentina (-700) over Saudi Arabia (Tuesday)

Breakdown: Hopefully, this is a bankroll-builder game. La Albiceleste are one of the pre-tournament favorites with superstar Lionel Messi leading the way. Losing, or even drawing, the opener against a team ranked 51st in the world would be a disastrous way to start.

PREVIOUS BETS

Sunday

Bankroll: $5,000

Today: Betting $205

Bet 1: $100 on Ecuador-Qatar draw (+205)

Breakdown: The rumors that eight players from Ecuador were bribed with $7.4 million to throw the opener and allow a second-half goal are probably bogus. Besides, a draw seems like a less suspicious outcome. Qatar can hold its head high for earning a result. Ecuador is fine with getting a point. And the conspiracy theories will just float away like a Wesley Sneijder free kick. Yeah, right.

Bet 2: $105 on Will Ecuador advance from Group A? (Yes, +120)

Breakdown: This could come down to the final game of the group when Ecuador faces Senegal. Had Sadio Mane not been ruled out of the tournament for Senegal, maybe this bet doesn’t get made. But the late news could unsettle the Lions of Teranga.
