Leinier Dominguez Perez shares the lead with Vassily Ivanchuk on 2 points after 3 rounds of the Capablanca Memorial elite group. Dominguez defeated Vladiir Potkin after the latter sacrificed the exchange rather unnecessarily in an at least equal position and then gradually went astray. Ian Nepomniachtchi missed a golden chance to score a win in an odd game against Viktor Laznicka where at first he got less than nothing as white, then his opponent gave up a pawn for pretty much no reason after which he almost certainly should have lost. Instead the game eventually drifted to a draw. Vassily Ivanchuk was allowed to completely equalise straight out of the opening by Yuniesky Quesada Perez and a draw was agreed in 33 moves. Round 4 Monday 7th May 2012 3pm local time, 8pm BST: Ivanchuk-Nepomniachtchi, Potkin-Laznicka, Dominguez-Quesada.
