Lautaro Guerra raised to 30,000 in middle position and Damian Salas defended from the big blind. The flop came 7♠4♠3♠ and Salas check-called a bet of 25,000 from Guerra.
The turn brought the 5♠ and both players checked to the A♠ on the river. Salas checked for the third time and Guerra put together a bet of 80,000. Salas check-raised to 240,000 and Guerra instantly folded as Salas was counting out his chips.
Aaron Barone raised to 30,000 from the cutoff, Yuto Misaka called in the big blind.
Barone bet 15,000 when the flop came 2♦Q♦9♦, Misaka check-called. Barone did not slow down on the J♥, and he bet again for 35,000, Misaka check-called again.
Barone continued his aggression with a bet of 125,000 on the board paring 2♣ river which left himself with one big blind behind. Misaka thought about his decision for around two minutes and made the call. Unfortunately for Misaka, Barone flopped a flush with the K♦J♦, and scooped the pot.
Ryan Hunsinger raised to 30,000 on the button, and only Hiroki Nawa called from the small blind.
Both players checked the Q♥10♦10♣ flop and moved on to the 6♦ turn.
Nawa elected to take over the betting lead, putting out a wager of 30,000, which Hunsinger called.
The river then added the J♦ to the board, and Nawa continued for 125,000. This time, though, Hunsinger responded by moving all in for around 300,000.
Nawa snap-mucked his cards, and the dealer sent the pot in the direction of Hunsinger.
Gustavo Morales opened to 30,000 in middle position and received an all-in shove for 350,000 from Oleksii Kravchuk in hijack. John Petro in the small blind called. Morales folded, and left the two players to head to showdown.
Oleksii Kravchuk: 10♣10♠ 
John Petro: A♣Q♣
Kravchuk's tens held on the flop of J♣9♣5♦ but Petro had more outs to turn things around with a flush draw. The 4♠ turn was not one of Petro's outs, but the river Q♥ was pushing Petro ahead and sending Kravchuk to hit the rails.
On a pot of 180,000 and a flop of Q♦8♣7♥, Yngve Steen bet 60,000 after action was passed to him in late position. Shane Klasnimi in cutoff folded but Vytautas Semaska in the big blind called to see a turn.
Both players checked the turn 4♥. Semaska fired 35,000 on the river 7♦ and got called by Steen. Semaska's turned two pair with 8♦4♦ was counterfeited when the board paired, giving Steen the higher two pair with K♠Q♥.
The remaining players in Day 4 of the Main Event have been sent on their final 20-minute break of the night. When they return, they will play half of Level 20, which is 60 minutes of play, before Day 4 wraps up.
Below are some highlights from Level 19.
Level: 20
Blinds: 10,000/20,000
Ante: 20,000
Wagner Wysotchanski and David Alvarez saw a flop of K♦2♣10♠ where David Alvarez had a bet of 500,000 in front of him from early position. Wysotchanski then moved all in for 1,275,000 in the hijack, and Alvarez snap-called.
Wagner Wysotchanski: K♥K♠
David Alvarez: 2♥2♠
Nearly 3,000,000 was at stake as Alvarez showed a flopped set of deuces, but Wysotchanski had top set of kings. Alvarez had just one out, and it failed to arrive on the 7♣ turn or 10♣ river as Wysotchanski earned the massive double up.
"Thank God it wasn't tens," Wysotchanski said after the hand.
Will Kassouf opened to 55,000 from early position and Joseph Altman three-bet shoved for 310,000 from the button. Kassouf called with a covering stack to put Altman at risk.
Joseph Altman: A♣Q♠
Will Kassouf: J♥J♣
The A♦9♥7♣7♥K♠ runout gave Altman top pair to double up through Kassouf.
