Things look dicey on board 4, as Evan dropped a piece in a queenless middlegame against Vadim Martirosov, though he does have two pawns.
On board 3, Yacov's position against WGM Anya Corke has undergone multiple transformations, starting as a Trompowsky, then becoming a standard IQP and is now a symmetrical BOOC middlegame. We'll either see quick peace or violence!
On board 2, Irina is pressing Denys Shmelov's kingside with an aggressive opening. White's chances look superior.
On board 1, Giorgi is defending against Jorge Sammour-Hasbun's double pawn sac and it looks unbalanced.
