WEBVTT 00:00.900 --> 00:10.050 Hi there in a slideshow, we illustrate the concept of probing the opponent's pawns so -- don't go 00:10.050 --> 00:15.750 backwards, so they reflect an irreversible style of decision, one which can cause regrets. 00:16.290 --> 00:18.260 And there's nothing you can do about it later. 00:18.270 --> 00:20.500 You can't reverse those decisions. 00:20.880 --> 00:28.500 So here Fisher against Adderson in the 1962 US championship is very interesting from a probing perspective. 00:28.830 --> 00:29.520 Let's have a look. 00:29.520 --> 00:39.750 So, E4 Anderson, play the Sicilian defense and we have a very nice he says the he takes 96, 96, 00:40.040 --> 00:41.290 93 ESX. 00:41.340 --> 00:49.860 This is commonly used as a way of entering into the caecilians vertical of the ninety five quite often 00:49.860 --> 00:57.000 players nowadays they most often play DCX and we enter as sentence of which is kind of trendy because 00:57.000 --> 00:59.850 Magnus Colston's popularized it in recent years. 01:00.090 --> 01:04.260 But here there is also a distinct variation with Bishop before in its own right. 01:04.830 --> 01:08.240 A slight downside of this variation is that it picks up the bishop pair. 01:08.730 --> 01:15.870 However, with the five black does seem in principle to have, you know, reasonable prospects and compensation 01:16.650 --> 01:20.220 we see of the eatings 965. 01:21.990 --> 01:26.700 Bishop detA is played so Ninety-eight see free Bishop Tacy free. 01:27.090 --> 01:34.110 So why does have this bishop hair and sometimes having a bishop hair and the bishop about a counterpart 01:34.650 --> 01:41.640 can lead to the potential for probing the opponents pawns, which is essentially, you know, systematically 01:41.640 --> 01:42.500 putting them here. 01:42.510 --> 01:48.600 There is there is a threat against the G7 --, which needs to be addressed in some way. 01:49.230 --> 01:54.720 We see the queen's coming off and Fischer as a player that likes to grind out wins. 01:55.770 --> 02:03.330 And sometimes you do need to get the opponent to make metal pole moves and weaken their position. 02:03.870 --> 02:10.230 You can't just rely on provocation strategies where you tempt the opponent's pawns forward to attack 02:10.230 --> 02:10.530 you. 02:10.950 --> 02:16.770 You sometimes need to actively probe the opponent's pawns to get them to move forwards. 02:17.550 --> 02:23.190 Once you get them moving forwards, those irreversible decisions, maybe you can start to more easily 02:23.190 --> 02:24.990 dismantle the opponent's position. 02:25.620 --> 02:28.260 We see FCX already a concession. 02:29.820 --> 02:34.470 This dance square with our counterparts in any games would surely love to eat up these pawns. 02:35.310 --> 02:40.980 We see efore kind of saying, you know, E5 is not going to easily blunt this pressure without a fight. 02:40.980 --> 02:44.010 You can have to isolate a pawn to to E5. 02:45.060 --> 02:46.800 So the bishop is kept at bay as well. 02:46.800 --> 02:54.860 And at the moment, unless Black wants to suffer an isolated Queen's Ball, you know, if it just doesn't, 02:54.890 --> 02:58.770 that also opens up the frontal attack against that pawn. 02:58.770 --> 03:05.040 The pawn without fellow pawns isolated is going to be, you know, weak pawns to really try and win 03:05.040 --> 03:05.490 later. 03:05.850 --> 03:14.630 So Black is contends with Bishop D7, Bishop CIFOR, we see Black Castling, White Castles, Kingsly, 03:14.640 --> 03:17.340 seven, Rook Daewon. 03:17.610 --> 03:23.730 So looking at that pawn, Rakoczy eight and now Caffrey, this is a dual purpose the rook can double 03:23.730 --> 03:32.580 sure to help the bishop look at ESX, but it also can probe via Jeoffrey can probe this G-7 pawn again. 03:33.780 --> 03:39.540 We see Bishopsgate and now Ruggie three probing move and you see this in the positional players like 03:39.780 --> 03:46.650 come off Petrosian, the structuralist generally so champions in your country. 03:46.650 --> 03:49.230 It might be Michael Adams in the UK. 03:49.230 --> 03:54.750 So if you look at games of Yassa, so I know he's not active, but he's a great structuralist. 03:55.410 --> 04:01.740 Look at the structure structuralists, how they probe the whole structure, trying to weaken the opponents 04:01.740 --> 04:02.580 pawn structure. 04:03.120 --> 04:08.430 You don't necessarily have to do active operations like the so-called minority attack to weaken the 04:08.430 --> 04:08.790 structure. 04:08.790 --> 04:10.920 You can just probe it or provoke it. 04:11.400 --> 04:15.150 But probing is more your proactive in probing. 04:15.810 --> 04:19.020 So we see Rook is seven rook jeoffrey. 04:19.560 --> 04:24.240 So at the moment it seems black can respond adequately. 04:25.260 --> 04:31.950 We see before and now there is an idea of B five and then bishop before to secure once the light leaves 04:32.550 --> 04:34.980 control of before we see the B5. 04:34.980 --> 04:38.970 So introducing Bishop before is a clear and imminent danger. 04:39.870 --> 04:42.030 We see that rook going. 04:42.030 --> 04:43.470 There's a bit of congestion here. 04:45.330 --> 04:46.740 That route goes to D7. 04:46.740 --> 04:51.200 If B sex then bishop before Skyring, you know, that's that's going to be great for white. 04:51.930 --> 04:56.460 So rook eighty seven and that we see Bishop differe looking at eighty seven. 04:57.210 --> 04:59.190 It's uncomfortable for black. 04:59.910 --> 05:10.410 We see a committal pull, move 86, this weakens even more sex, but it also puts another -- on a 05:10.680 --> 05:11.160 square. 05:13.170 --> 05:22.560 If EF five, that would have left a big hole in Blackpool's Rashaun E5 Outpost's for why is also winning 05:22.560 --> 05:23.640 material there immediately. 05:24.120 --> 05:26.190 So age sex is played. 05:27.360 --> 05:28.200 Rob, Jeoffrey. 05:29.310 --> 05:31.730 And it looks as though is this like pointless? 05:31.890 --> 05:34.080 Would you really plan move like Jeoffrey. 05:34.620 --> 05:36.340 What is the expectation. 05:37.510 --> 05:39.210 OK, let's run with it. 05:39.600 --> 05:40.710 B sex is fight. 05:41.670 --> 05:44.210 And the point is because we're looking at G7. 05:44.250 --> 05:45.270 Hold on a sec. 05:46.140 --> 05:49.980 Isn't that potential killer Colin Square G7? 05:52.200 --> 05:59.240 Bishop before ouch, if the bishop goes to fight, what do we do about this --? 05:59.610 --> 06:01.130 It's like squid's this one. 06:03.090 --> 06:06.030 There's a method in the madness here from Fisher took the fall. 06:07.110 --> 06:12.360 For the moment, though, we'd like to play Bishop a fight, but we don't want this downside, you know, 06:12.720 --> 06:16.320 rotates efore, not route rotates F4. 06:16.320 --> 06:18.150 So we address that. 06:18.150 --> 06:20.430 We're threatening now Bishop Efate. 06:23.280 --> 06:29.010 How does Black responds here, this is rather tricky, this situation. 06:30.690 --> 06:36.590 Rather tricky indeed, Black responds with might be somebody in this position, you might wonder why 06:37.290 --> 06:43.790 why not shield with five F G five F takes offtakes. 06:45.120 --> 06:47.890 Well, that is damage in its own right. 06:48.330 --> 06:56.190 There's work of six year looking at six blocks, piece pieces, a pretty passive had that bunched up 06:56.190 --> 06:56.930 and passive. 06:57.900 --> 07:02.490 What happens with Eighty-six here if we just take on G5? 07:03.390 --> 07:04.550 This is a disaster. 07:06.510 --> 07:13.080 So 97 was chosen inviting Bishop Efate, it seems, and Black is getting a bit dismantled out of the 07:13.080 --> 07:14.090 Bishop 67. 07:15.330 --> 07:18.010 So the probing had great effects. 07:18.570 --> 07:20.820 To be fair, this is a bit of a sideline opening. 07:20.820 --> 07:27.630 It's not usually thought that great to give the opponent the bishop power if the opponent is oblivious. 07:28.830 --> 07:34.380 So the concept of probing, they might not see the benefits of probing the opponents pawns to force 07:34.380 --> 07:39.430 them to move forward, using that bishop as a great use of the bishop in this example. 07:39.900 --> 07:46.710 So we see the bishop going now to 1963, but still there's two pawns being targeted and its absence. 07:47.430 --> 07:52.050 And if F7 has played, if Rook takes differe, that we could take. 07:52.050 --> 07:56.790 And this position, even though it's obviously colored bishops, this is great for this position of 07:56.790 --> 08:03.240 the Czech Bishop E5 This is great for White with resting Rocsi seven Czech no time for Naughtie business. 08:04.530 --> 08:05.550 And here. 08:05.670 --> 08:12.210 Yeah, we've got a great position and we can come back and all, you know we can do this G4 move and 08:12.210 --> 08:17.310 this is just all great for why, why it's going to create a major passport here. 08:17.970 --> 08:29.530 It's crushing, you know, with a five and B6 crap crack to crack open a passport on the queen side. 08:29.850 --> 08:37.020 So anyway, so Brooke, F7 is played, not indulging, not thanks to free. 08:40.920 --> 08:50.330 We see Desex King these things, and now another one bites the dust, Bruzzese free rotates 86 another 08:50.340 --> 08:55.140 point by saying dust should be seven e five. 08:55.160 --> 08:57.150 Check kindie five. 08:58.920 --> 09:06.770 If the king has gone to D7 then as that heartattack to face Roxxy seven check and this check. 09:06.780 --> 09:14.420 And this is just nasty disposition for like for example like this where it's a disaster for black, 09:14.430 --> 09:15.630 it's absolute disaster. 09:17.070 --> 09:19.130 That's actually check and mate. 09:19.560 --> 09:28.530 So King D5 was played and we have a full routley to entrain King CIFOR, Rook AFTA. 09:29.160 --> 09:35.100 So where the probing has occurred and where is like taking pause that gives rise naturally to your own 09:35.100 --> 09:35.400 past. 09:35.400 --> 09:42.570 -- Then they have less barriers to go down the boards becoming menacing passports. 09:43.710 --> 09:53.340 So you has support given for geto and now the passport is free to run up the board potentially. 09:54.000 --> 09:58.440 EFO Ruggie seven the rook offers it supports on route. 09:58.740 --> 10:01.020 So the bishop is not just going to step it up for nothing. 10:03.810 --> 10:06.840 We see King Taizé for H5. 10:06.840 --> 10:15.400 Without further ado, without further delay, another eight, six and then seven black. 10:15.420 --> 10:19.620 It gives up the bishop, but it's an easily one possession. 10:19.800 --> 10:22.020 This passport is now ready to roll. 10:24.420 --> 10:25.950 OK, the opponent resigned. 10:25.970 --> 10:27.270 Harrison resigned. 10:28.620 --> 10:38.160 Fisher for sure, outclassed many of his fellow U.S. competitors and as well as later getting a record 10:38.470 --> 10:40.830 federating in general. 10:42.270 --> 10:46.320 But here, this example with the bishop here is interesting. 10:46.320 --> 10:49.230 Interesting is the bishop probing the opponents pawns? 10:49.710 --> 10:55.260 You don't have to wait for the opponent to slip up with pushing pawn voluntarily. 10:55.590 --> 10:57.120 It's an irreversible decision. 10:58.050 --> 11:03.000 And as such, maybe you can sometimes provoke your opponents pawns forwards by doing nothing. 11:03.000 --> 11:05.910 Sometimes all you can do probing. 11:06.090 --> 11:07.440 It's an active operation. 11:07.650 --> 11:11.610 More on the active side, especially if you've got an asset like the bishop there. 11:12.180 --> 11:19.950 It's a great use of the possibilities of having the bishop power to probe the opponent's position, 11:20.580 --> 11:21.750 encourage weaknesses. 11:22.230 --> 11:26.910 When you win a key pawn or two, you've got the magic of passports, you're winning. 11:26.910 --> 11:31.200 Probability shoots up as soon as you got passports. 11:31.860 --> 11:38.040 OK, I hope you enjoyed that one and got some thoughts there for probing in your own games and so much.
