Ivanchuk and Sevian lead Capablanca Memorial midway through

Chuky beats the locals

Ukrainian fan-favourite Vassily Ivanchuk has dropped out of the 2700 club, but his skills seem to gain new life when he travels down to Havana. 'Chuky' is the second seed and is currently leading the field. To do so, he first took down Cuba's number five in the ratings list Yuri González. Ivanchuk had the white pieces and gobbled up a pawn on the queenside in a heavy-piece middlegame:

After 32.♕xa5 Black cannot capture on c6 due to 32...♜xc6 33.♖xc6 ♜xc6 34.♕a8 gaining the rook with the fork. Later on, the c-pawn got to the seventh rank and González decided it was time to call it a day.

Immediately afterwards, Vassily defeated the other Cuban in the field, Carlos Daniel Albornoz. He did it from a Petroff Defence with Black — the "drawish" defence continues an already lengthy revival after Fabiano Caruana popularized it on his way to the 2018 World Championship match. Black had more space and took advantage of White's over-confident play shortly before the time control:

The Reliable Petroff

The Petroff (or Russian) Defence which is characterised by the moves 1.e4 e5 2.Nf3 Nf6 has been popular at the highest levels for many years and enjoys the reputation of being an extremely solid defence.

It is already difficult for Albornoz, but after 37.f3? ♜e3+ 38.♔c2 ♜e2 the Cuban grandmaster gave up, aware of the fact that Black's initiative is too much to handle.

Sevian continues on the rise

18-year-old Samuel Sevian impressed during this year's US Championship, although his lack of experience played against him in the final stretch. Despite having started with three Blacks in five games, he is in shared first place on +2. 

After defeating Albornoz in the opening round and drawing Antón the following day, he beat Adhiban Baskaran a.k.a. "The Beast" with White. Samuel gained a couple of pawns in the middlegame and never looked back:

The current openings theory with 1.7 million games

Here the youngster realized the exchange of queens would favour him and played 25.♖f5. Black's best option is to accept the trade with 25...♞c4, and after 26.♖xg5 ♞xd6 27.♖d5 White is set to take the point if he handles the technical phase appropriately. Addhiban resigned on move 40.

Addhiban's woes continued in round four when he played the King's Indian against recent Prague Challengers winner David Antón. A tense struggle arose after the players castled on opposite flanks, and when the position was opened up White's initiative was for choice. In the end, Antón's passed d-pawn allowed him to win an exchange.

Black gave up the exchange by playing 41...♝xe7 — in case of 41...♜ec8 White has 42.♗g8 and after 42...♜xg8 43.♖xg8+ ♜xg8 44.♖xg8+ the d-pawn promotes. Adhiban resigned four moves later.

The final round prior to the rest day was the first one to finish with all three games drawn. Carlos Albornoz and David Antón only played sixteen moves each, but the battle did not lack emotion as White was forced to go for a perpetual while in material disadvantage.
