[8] In an interview with Pitchfork Media given before the release of Hey Venus!, singer Gruff Rhys claimed "Show Your Hand" was "a song about gambling.

[9][14] "Emphatic power chords" takes the song into the "rarefied soft-rock territory" of the chorus with Rhys singing the title phrase four times before being joined by "sugar-sweet harmonies from the Brian Wilson School of Spine-Tingling Pop" on the last lines: "I'm jumping off the fence, into your corner".

Although some critics hailed the track as a 'return to form' for the band, with the Manchester Evening News describing the song as a "the best that the Furries have sounded in ages ... a return to the mellow-but-bouncy pop fare of their early albums Fuzzy Logic and Guerilla",[16] others pointed out that "Show Your Hand" is "ponderously mature",[5] rather "straightforward" and "more like the generic pop songs one would find on the radio than [that] of a historically experimental band".

[6][17] However, The Guardian stated that "Show Your Hand" "is the sort of music [the Super Furry Animals] do best - hazy, lazy sunshine pop".

[17] The 'retro' nature of the track was commented on by several critics with The Independent describing the track as being performed in a "sophisticated soft-rock style" which recalls "the arrangements of The Association and Surf's Up-era Beach Boys",[15] Pitchfork Media calling the song "Zombies-esque orchestral pop",[19] and Drowned in Sound describing "Show Your Hand" as "an almost Bacharachian gem":[20] Swimming in the dreamy swathes that typified Phantom Power rather than the acid-pop that provides their real edge, "Show Your Hand" is still hewn from a rich seam and glides on a joyously melodic horn and vocal exchange.

[20]BBC Wales described "Show Your Hand" as "classic Furries" in a favourable review on their website to coincide with the release of the track as a single going on to state that it is:[7] A song of gambling and indecision, with a dark edge and plenty of clever wordplay, it's a perfect record to lift dampened spirits this summer.
