Jonathan in the Spanish this was no great surprise. Although he hadn't played
this move in this specific position beforehand the ideas are similar to the
ones after 4...g6, which he chose against me last time.} 5. c3 g6 6. d4 exd4 7.

worth further investigation.} {The game from the database continued} 10. Qxa4 (
10. Nc3 $146 {This new move playing for quick development looks more
interesting to me as I think White really needs to do something pretty quick
in order to achieve an advantage. At the moment Black's position is slightly
vulnerable with moves like Nd5 and Bg5 coming up. A possible continuation is}

position offer mutual chances but I would personally prefer Black here as he
has the long term trump of the pair of bishops.}) 8... d5 {The most logical
reply in my opinion. However} (8... Bg7 {is slightly more popular. Now there
might follow} 9. d5 Na5 10. Bd2 $1 {when White's score is huge. The tactics

moment. A fully playable move but not the most testing for Black.} ({Instead}

a bind on the kingside but Black's light square control on the queenside

{This game was played in the 3rd round of the Dutch championship 2018 in
Amsterdam. The win in this game allowed me to take the lead in the tournament
with 2.5 points out of 3.} 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 b5 5. Bb3 g6 {
My opponent in this game Ivan Sokolov is a very experienced player. We had
played a huge number of games before that one. But here Ivan manages to
surprise me choosing an obscure modern line of the Ruy Lopez. I was expecting
a much more solid choice here. This variation is becoming popular due to the
practice of S. Mamedyarov.} 6. a4 {Since I was not familiar with the recent
theoretical developments of this obscure line, knowing only the traditional 4..
.g6, I decided to compare the positions with and without inclusion of the
moves b7-b5, Ba4-b3. And, of course, punishing my opponent for such strange
play in the opening came into my mind. White has a development advantage, and
when one has the advantage in development it is necessary to open the position
and play for attack. This is what I was trying to do in the coming moves!} b4 {
