Ivey bizarrely responded by throwing in half his total chips in to raise the pot a further $2.7 million to $3.6 million.
The ultra cool competitor gave himself up for the accidental blockbuster raise when his arm darted back out to the chips in the middle of the table when he realised he'd thrown in a small fortune.
Ivey was able to play it cool from that point on with his face showing no signs of the panic he must have been feeling inside.
Badziakouski sensed immediately that his rival had just committed a blundersome error and a huge grin flashed across his face.
The live TV telecast estimated Badziakouski had a 62 per cent chance of winning the pot if he'd have decided to call Ivey's blind bluff.
However, in a moment that will cause him agony for a long time to come, Badziakouski wrestled with the decision for more than 90 seconds, before ultimately deciding not to meet Ivey's drastic raise 3-bet raise.
After throwing in his cards to give Ivey the pot, Badziakouski immediately challenged the American WSOP hall of famer about the "misclick" — but Ivey refused to reveal his secrets.
By the end of the hand, Ivey had picked up a cool 925k addition to his chip stack and was back among the high rollers sitting at the final two tables of the event which began with more than 100 competitors.
Unfortunately the hand appeared to throw off both of the players involved and they were both casualties late on day two as the field was whittled down to a final table of seven players.
Despite his incredibly lucky streak Ivey eventually crashed out with 12 players remaining.
German Dominik Nitsche is the chip leader on $46.5 million heading into the final day of play in the Czech Republic in the winner takes all $400k event.
Meanwhile, Ivey's reappearance on the WSOP has surprised some poker commentators as he continues to fight a $9.6 million lawsuit verdict which saw him forced to hand back his winnings from a Baccarat game at Borgata Hotel Casino in Atlantic City
The casino's lawsuit alleges that Ivey exploited manufacturing flaws in playing cards during four sessions of Baccarat at the casino in 2012.
He is reportedly yet to pay back the money and is continuing to fight the verdict.
