WEBVTT 00:01.050 --> 00:01.950 Hi there. 00:02.250 --> 00:05.560 In this lecture, I'd like to show you an amazing game of execution. 00:05.790 --> 00:07.950 Where it is on the counterattack. 00:08.370 --> 00:15.060 Of course, they said the Masters of Defense have contributed as much to the history of chess as the 00:15.060 --> 00:17.550 players of attacking style. 00:19.110 --> 00:25.110 But you could argue, you know, counterattack, which is the best form of defense to attack, is a 00:25.110 --> 00:26.250 kind of attacking style. 00:26.250 --> 00:29.990 You're getting the opponent to commit, for example, pawns which are irreversible. 00:30.000 --> 00:35.040 And this is one such example, Game 19 €50 championship. 00:35.700 --> 00:44.160 We have Sergei Kamsky against Viktor Korchnoi, so E4 C5 and we have a Grand Prix attack version 1.0. 00:44.160 --> 00:47.370 So no night three fastest F4 straight away. 00:47.800 --> 00:58.560 Of Korchnoi here plays six we see 9c3 now e6e5 95 white takes on d5 e takes Quinn f3. 00:59.460 --> 01:06.300 We have D4, Bishop C4, Bishop E7 and now already an inaccuracy F5. 01:06.300 --> 01:10.080 It looks aggressive but it is a bit weakening. 01:10.080 --> 01:13.620 More prudence would have been nine stage three. 01:13.770 --> 01:24.060 So if both sides castle d6 d this should be a position where White has an advantage as example, but 01:24.060 --> 01:25.790 with F5 it's quite committal. 01:25.800 --> 01:35.400 We see Knight C6 so attacking E5 and the Queen moves again to protect C5 plan castles free and now Korchnoi 01:35.430 --> 01:39.450 is able to play a very energetic counter here. 01:39.630 --> 01:41.640 Can you see what it is at ten points? 01:42.090 --> 01:42.960 Very energetic. 01:42.990 --> 01:47.550 D5 So e takes D6 is played. 01:47.760 --> 01:50.940 If Queen takes D5, we can just take on F5. 01:50.940 --> 01:52.650 It's a very pleasant position here. 01:52.920 --> 01:55.680 This Black is doing very well. 01:55.710 --> 01:57.480 E5 is painfully weak. 01:57.840 --> 01:59.190 There are pressure points. 01:59.280 --> 02:04.530 If Bishop takes D5, Bishop takes F5 and then we get a lovely position here. 02:04.740 --> 02:06.960 So why has overstepped things? 02:06.960 --> 02:11.640 It seems because this position white has a lack of harmony. 02:11.640 --> 02:14.130 This bishop and rook, they're still asleep in bed. 02:14.130 --> 02:16.050 They're not part of the attacking team. 02:16.800 --> 02:21.930 We have white castling Queen f6 so black is significantly better at this point. 02:22.210 --> 02:24.450 Now another weakening move. 02:24.750 --> 02:27.450 Can you say this is an attack or just self weakening? 02:27.450 --> 02:31.650 It's really making things ripe for a counterattack. 02:32.280 --> 02:36.300 There are weaknesses around the king here to potentially tap into. 02:36.630 --> 02:38.310 If Bishop de Fray. 02:38.310 --> 02:42.540 On the other hand, Black is better with Knight before this position. 02:42.540 --> 02:49.830 Taking out the bishop means that this bishop without a counterpart could wreak havoc in the white position 02:49.830 --> 02:51.960 later, for example. 02:52.470 --> 03:00.390 So here, say with B6 as well, we can get a very nice use of the Bishop with Bishop A6 here concretely 03:00.390 --> 03:06.570 against the Queen and Rook securing winning with zero so horrible things could happen to white there. 03:07.320 --> 03:19.380 So anyway G4 though we have Bishop D7 Queen e2 if the free hand coming if D3 her rook ice this position 03:19.380 --> 03:27.390 with Queen D five Knight before strong here G5 this is just ridiculously good for black so Queen E two 03:27.930 --> 03:28.800 is played. 03:29.490 --> 03:36.450 We have rook e8 so Black's kind of developed all the pieces, all the team is out and about and now 03:36.450 --> 03:42.960 aiming to weaken the king to give further defines more refines and defines roles and responsibilities 03:42.960 --> 03:45.570 to this attacking potential team. 03:46.110 --> 03:52.140 Whilst White's team is half asleep here with the Bishop rook still in bed, we have Bishop d5. 03:52.260 --> 03:55.680 If Knight takes E5, Rook takes E5. 03:55.680 --> 03:59.880 This position doesn't matter about G5 looking aggressive. 03:59.880 --> 04:05.430 Black's got all the pieces in good positions and here Bishop C6 for example. 04:05.430 --> 04:09.510 This is just very dangerous for white indeed, it's losing for white. 04:10.140 --> 04:15.720 There are just too many weaknesses here and you can see the whole team is looking for things like Rook, 04:15.720 --> 04:18.390 G4 or Rookie too. 04:18.420 --> 04:20.500 This is also crushing here. 04:20.650 --> 04:32.880 Ouch meeting if D3 then Bishop C6 is a nasty pen and winning exchange or delaying winning exchange to 04:32.880 --> 04:38.970 delay gratification reaps even more rewards here so we can play it like this. 04:39.060 --> 04:42.090 And this is just really a strong position. 04:42.090 --> 04:47.670 The free Czech rookie turtle crashing through with big advantage for black. 04:47.970 --> 04:54.360 So anyway, Bishop D5 is trying it and now we have a great move, which is kind of weakness of the last 04:54.360 --> 04:54.690 move. 04:54.720 --> 04:56.340 It's neglected D free. 04:56.340 --> 04:59.940 So guess what cautionary plays here, which kind of limits the opponent. 05:00.120 --> 05:03.840 Team potential that only be a subset of the team involved here. 05:04.170 --> 05:05.700 So what do you think that is? 05:05.700 --> 05:07.920 Which limits one's teamwork potential? 05:10.690 --> 05:11.130 Okay. 05:11.170 --> 05:11.910 It's different. 05:11.920 --> 05:16.690 So it's shutting down the bishop and the rook and the cost of the pawn delaying their development. 05:16.960 --> 05:17.980 We have. 05:20.170 --> 05:21.520 Now it takes five. 05:21.520 --> 05:23.130 We have Rogue Taxi, five, G five. 05:23.140 --> 05:24.760 So Wayne still trying to attack. 05:25.090 --> 05:27.310 But we've not too many team members. 05:27.970 --> 05:28.850 It's not all the team. 05:28.870 --> 05:32.800 If Queen is seven, this was also possible. 05:32.800 --> 05:36.010 Just, you know, encouraging, even six with tempo. 05:36.310 --> 05:39.970 This position is still just to show the extent of Black's resources. 05:40.390 --> 05:45.220 It's a position where Black ends up better because of that disconnect. 05:45.340 --> 05:51.580 Even though blacks the exchange down in this fascinating position, blacks still doing very well. 05:51.580 --> 05:57.730 You can see that the teams, the team of black pieces are still overwhelming for white here in this 05:57.730 --> 05:58.390 scenario. 05:58.690 --> 06:00.880 So it could end up like this just for the record. 06:00.880 --> 06:02.710 But Queen D ain't waiting. 06:02.710 --> 06:04.810 Courage F thinks by f6. 06:04.810 --> 06:14.110 Now we have C for this just locks down further locks down white spaces opens up Bishop See five possibilities. 06:14.110 --> 06:19.150 All the diagonal possibilities we have G6 It looks as though, Well, isn't this really scary? 06:19.150 --> 06:21.070 Because the F seven pawn is pinned. 06:21.490 --> 06:24.040 We have Bishop C five check King H one. 06:25.270 --> 06:28.380 And now a terrifying looking move is played by cornering. 06:28.390 --> 06:35.020 H takes G6, which positively invites using the F seven pin pawn of Queen six G6. 06:35.020 --> 06:37.150 Why would caution play in such a way? 06:37.240 --> 06:42.970 There is an option with G tanks F six and G takes a seven shank. 06:42.970 --> 06:46.780 You'll note that G eight is amplified, but it's not quite enough. 06:47.200 --> 06:49.780 So in fact, here we can just take the rook. 06:49.780 --> 06:59.050 There's no rook g one if b4 time for Bishop B two we have rook 65 with the idea that if Queen 65, Bishop 06:59.080 --> 07:04.000 c6 if B take C5, we just get marvelous position with Bishop C6. 07:05.470 --> 07:13.420 And then you know where is once attack We can play even rook default with a frets on the queen immediately 07:13.540 --> 07:17.110 that's crushing And here you know this is just a crushing position. 07:17.890 --> 07:25.900 So okay, we have a G6 though, which invites Queen sized G6, so really provocative. 07:26.320 --> 07:28.420 But there is one move and one move only here. 07:28.420 --> 07:34.210 So of course, noise, precise calculation kind of reassures he must have been reassured by his calculations 07:34.210 --> 07:39.100 here because you wouldn't play this otherwise, because it looks as though, you know, plants get mated. 07:39.100 --> 07:39.940 So guess what? 07:39.940 --> 07:44.680 Move which triggers a massive counterattack here for 100 points. 07:44.680 --> 07:47.230 What move is played here for that counterattack? 07:49.750 --> 07:50.770 It's a fun one. 07:52.480 --> 07:54.520 Queen takes up sex, the king is weakened. 07:54.520 --> 07:59.050 So in theory, we can try and get a lot of roles and responsibilities for our pieces. 07:59.410 --> 08:02.110 On this backfire, we have to have sex. 08:02.650 --> 08:04.270 If Queen takes offence. 08:04.270 --> 08:06.400 Yeah, we're just taking on sex. 08:06.400 --> 08:12.640 Taking on key to this endgame is just hugely favourable to us, this position. 08:12.640 --> 08:15.640 We're just simplifying and getting a winning endgame. 08:16.300 --> 08:21.970 So Rook saying f sex rookie one check. 08:24.290 --> 08:30.740 So this is a really interesting position Rook takes D5, believe it or not, is also a possibility. 08:31.070 --> 08:35.510 So here Black's pieces are really quite dangerous. 08:35.510 --> 08:40.340 So here, for example, Black's still got a huge attacking potential. 08:40.970 --> 08:43.790 Bishop C6 check, rook G4 check. 08:44.090 --> 08:47.060 And the Queen is going to be one at some point here. 08:47.420 --> 08:54.950 So for example here Bishop D free check rookie to check Rook six check Without the Bishop and Queen 08:54.950 --> 09:00.380 helping Black's team members will recoup the material with interest. 09:00.890 --> 09:06.470 So rookie one Centeno was played King G2 Rook g1 one King, F3. 09:07.650 --> 09:11.570 And now the point is definitely not Rook G6 here. 09:11.600 --> 09:13.850 Because Rook takes G6 and White's winning. 09:15.650 --> 09:18.320 No, this is a counter-attack against the king. 09:18.320 --> 09:18.950 Rook have one. 09:18.950 --> 09:21.710 Czech king G2. 09:22.400 --> 09:25.130 If King E4, we just play rookie eight check. 09:25.130 --> 09:32.330 And if rookie is six Rook Sorry Bishop takes E6 is crushing with the idea of bishop and five double 09:32.330 --> 09:43.670 check and mate So king G2 and now we have Rook takes f6 queen in four so the whole black team comes 09:43.670 --> 09:44.840 swarms over White's king. 09:44.840 --> 09:52.400 Now once we can king if Queen h5 instead Rook have five queens before we can take out D5. 09:52.520 --> 09:56.390 A lot of material for the Queen, so. 09:56.660 --> 09:57.350 Okay. 09:57.350 --> 09:59.720 And if Queen Alfred has to continue this for a moment. 09:59.720 --> 10:02.690 Rook G5 check, we can see Rook g1 is checkmate. 10:04.350 --> 10:05.700 So, yes, beautiful stuff. 10:05.700 --> 10:07.380 And if she takes the free hair. 10:07.410 --> 10:08.340 Bishop, thank you for. 10:08.340 --> 10:09.000 Of course. 10:09.120 --> 10:15.780 So Queen all is tried Rookie eight C takes different in desperation. 10:15.870 --> 10:20.370 If Queen takes C for rookie to look at the black pieces. 10:20.370 --> 10:25.150 Just working very well as a team to checkmate the king there. 10:25.200 --> 10:30.810 So C takes different C takes different still of lock and key on these pieces. 10:33.960 --> 10:40.500 Black could have played rook takes e4 her and this position is favorable as you might suspect for black. 10:41.220 --> 10:43.850 So this position plants got the advantage as well. 10:43.860 --> 10:47.280 So C takes D free though letting white have the queen for a moment. 10:47.280 --> 10:53.250 More queen takes D3 Black wants to checkmate to end the game of game ending downside to checkmate with 10:53.250 --> 10:54.130 these pieces. 10:54.150 --> 11:00.330 The white king King Geoffrey Bishop have to check King G to rook g1. 11:01.140 --> 11:02.160 Checkmate. 11:03.240 --> 11:04.520 Brutal stuff. 11:04.530 --> 11:07.410 What we're seeing in many, many vector cautionary games. 11:07.410 --> 11:12.780 If you study caution on games, counterattack games, you can find classic counterattack games. 11:12.930 --> 11:15.810 Know Google kortschnoi counterattack chess games. 11:15.810 --> 11:18.960 Com you'll get lots of counterattack game examples. 11:19.170 --> 11:21.480 But you know, this is a classic for me. 11:22.590 --> 11:28.320 It's not in so many collections, but it's pretty clear that White was encouraged to attack and the 11:28.320 --> 11:33.330 expense of committal pawn moves, irreversible pawn moves, creating king safety weaknesses around the 11:33.330 --> 11:33.900 king. 11:34.350 --> 11:39.480 Weaknesses around the king do kind of further make it more precise. 11:39.480 --> 11:45.630 What roles and responsibilities your your team of Pacers can have covering escape squares crane checks. 11:45.630 --> 11:51.660 But there's also limiting the opponent's teamwork with that D3 free move dislocating White's position 11:51.660 --> 11:53.220 preventing ordering development. 11:53.430 --> 11:56.840 So yes, the team imbalance was pretty clear here. 11:56.850 --> 12:02.250 Black always seemed to have a large number of team members, but unfortunately, like taking his position 12:02.250 --> 12:06.090 to the brink of seemingly grave dangers. 12:06.090 --> 12:12.990 But through tactics and combinations, he could prove this vacuum of weaknesses will backfire on the 12:12.990 --> 12:14.190 attacker in this game. 12:14.190 --> 12:15.000 Example. 12:15.000 --> 12:20.910 So yeah, and on fun of counterattack, letting the opponent come at you to weaken themselves. 12:21.180 --> 12:24.810 And you could argue, you know, Tigran Petrosian is a little bit like that through strengthening his 12:24.810 --> 12:26.340 position, not doing much. 12:26.340 --> 12:29.520 And opponents can sometimes self-destruct against that as well. 12:29.670 --> 12:35.010 But Korchnoi kind of being provocative here to, you know, in a more literal way to get the opponent 12:35.010 --> 12:36.150 to weaken themselves. 12:36.990 --> 12:38.580 Okay, I hope you enjoy this game. 12:38.580 --> 12:42.270 Example The great Viktor Korchnoi had so much.
