England have played a joker by picking two hookers on the bench against Wales as attack coach Scott Wisemantel compared the World Cup warm-up Tests to a game of poker.
The second instalment of a doubleheader against the Grand Slam champions unfolds in Cardiff on Saturday with Eddie Jones' men drawing first blood at Twickenham last weekend in the form of a 33-19 victory.
Twenty-four hours earlier on the other side of the equator, Australia sent shockwaves through the global game by overwhelming New Zealand 47-26.
England have made three changes to an experimental side, as well as choosing both Jamie George and Jack Singleton on the bench, while Wales have picked many of their established stars.
Wisemantel refuses to read too much into what happens during the build-up to Japan 2019 knowing it is part of the phony war.
"We watched the Wallabies game but we're not worried about them. All the teams at the moment are taking bits and pieces out of their games," the Australian said.
"It seems that teams are just holding something back. It's like a poker game at the moment.
England enter their clash in the Welsh capital knowing that a victory by 16 points could lift them to the summit of the world rankings.
Curry (shoulder), Wilson (ribs) and Underhill (toe) are involved in training and should play some part in the remaining two warm-up games against Ireland and Italy.
Centre Henry Slade, however, might miss all four Tests because of his knee injury and has tentatively been penciled in to face Italy on September 6 – the same date it is hoped his Exeter colleague Jack Nowell will return from an ankle problem.
World Cup bolter Ruaridh McConnochie will make his England debut on Saturday a week later than hoped for after overcoming a hip problem.
The Bath wing and sevens specialist was picked in the team to face Warren Gatland's men at Twickenham last weekend but was among a trio of late withdrawals due to injury.
