 David Navaras scored a beautiful win against Natalia Buxa. He joins us in our studio and breaks it down for us. David, an interesting and instructive win with the white pieces today. Are you pleased with the way you played? Yes, I think it was not an easy game because Natalia played the opening quite well and the position was equal but at this position I don't like the move A6 that much because I think black should take some measures against d5 which is threatening. So your idea has to go d5 and you feel until now Natalia had played reasonably? Yes, I think the position is equal but I don't know what to do with black now because after knight f6 there's d5 anyway and now either e5, knight d4 as in the game or perhaps bishop e5 when queen a8 is too risky for many reasons starting with rook c7 and also including some knight d4, knight f5. David, this idea of d5 is quite a thematic and a nice idea but you just give up a pawn. Can you explain to our viewers the rational behind giving up this pawn? Okay, I have a nice pawn center but it can also become weak and to make it a method I have to do something and I cannot do anything on the queen side. I would like to attack black's king but to do that I need to sacrifice a pawn. And open your bishop on b2? Yes, open my bishop and now I played e5 because if white takes there's queen d6 for example when the bishop on h3 is misplaced. And of course this is not your idea to play d5 to go into this position? Yes, I played e5, certainly e6 and maybe it's probably it's not bad for black yet but it's very hard to defend such a position. After knight f8 I can also play e6 when f6 is hard for black and after f6 white is probably winning by force playing knight e5. Let me help you. Thank you. Knight f7. I didn't just get stocks and and queen takes e6, threatening a smothered mate among other things. And okay, knight c5 looks logical but maybe rook e8 was not the best move but I don't know to recommend here because it's really hard. I really like this move knight d4 because maybe black actually wants to give this pawn backward d4 to activate the bishop on b7 and you just kill this bishop with this pawn sacrifice and then knight d4. Yes, maybe but I'm also preparing e6 as well as knight f5 so it's a typical multipurpose move. Yes. And now rook e8 is probably not optimal but it's hard to suggest anything else e6. Now if black takes like this I can take his bishop when there are seven deadly chess pins as Grandmaster Raozen would have probably formulated it. I'm certain queen f7 knight f5. Seven deadly chess pins. Yes. I love it. So it's after the books seven deadly chess pins. Is that one of your favorite books because a lot of players talk very highly of this book. I read it and liked it. I mean back then I was already a strong GM so it has not influenced me that fundamentally maybe also because I read it several times, not several times, several years after it had appeared but it's quite a good move, quite a good book. Sorry I'm thinking about moves already and now what has a decisive attack. Yes. Bishop f5 after g6 I'm ready to take. So if something like this you just... Yes and I have knight f5 in the end. Yes. And that's just one deadly pin but it's more than enough. Yes. And h6, queen g6. In fact there are some nice lines in the end and now I even considered playing for... Playing for crowds like this but luckily I avoided this temptation because it doesn't really work. Because here... Maybe even queen d6, queen f8 is not that bad but I disliked bishop c6 because if black just takes there will be numerous threats including queen f8 but the problem is that if black plays bishop c6 I don't know what to do now. Black can block the e file if needed in some lines. I mean if I give two checks it's not that terrible. You mean with knight e4 in the end? Yes. Probably or even can take d6 in some lines. Yes. Yes but I mean... There's no need to play like that. Yes. Exactly. This is good. Thank you. And now I expected knight e5 after which what can I play prosaic move f4 and then knight f5 was made as in the game. Because of queen h8 so something like this just runs into. Yes. Or there is a nicer solution knight f5 immediately and now an accurate move rook c1. Yes. This is really nice because it reminds me of the concept of the kill zone. So you just trap the king and there's no defending against mate. Yes. And if knight e4 there is a check and yes then there will be mate on h8 if black moves her bishop or her knight. That's a very pretty finish. Yes and today's even there's an even prettier line with a rook e5 and now knight e4 and now there is mate in 3 actually. So here you just... Yes. And queen e8 in the end. Yes. Exactly. That is that's absolutely stunning and in the game also rook e4 just knight f5 finishes the game because there's no defense against queen h8. Yes. Actually Natalia has been having quite a good tournament so far. Did you see her games before? Yes. I saw she bet Noel Studer in the previous round in Sveshnikov variation and okay there are six rounds left so she might improve her result after this loss. I mean one loss doesn't matter that much in a long tournament. Yes and but you are now on three out of four feeling good after today's game. Yes. All right well we wish you all the best. Thank you for joining us. Thank you for time David. Thank you for your attention. See you later. Thank you. See you David.
