対局日：2017-03-19 手合割：八枚落ち 下手： 上手： 手数----指手---------消費時間-- *Kifu commentary by Madoka Kitao (ladies professional 2-dan). * *Title: An 8-piece handicap game with student M * *Ms. M has played perfectly against me at 9-piece handicap, so this time we played at 8-piece handicap. I was told that she practised using Piyo Shogi. * *At 8-pieces, the handicap giver has two golds, so it's not possible to promote the major pieces just by moving them. *What is more, even after promoting them it's impossible to break Uwate's camp using only the horse and the dragon, because there are as many as three defensive pieces (the king and two golds). * *OK, so what should we do? * * *Terminology: *Shitate = Handicap taker *Uwate = Handicap giver 1 ３二金(41) ( 0:00/00:00:00) *At 8-piece handicap, we should first: 1. Break the edge using a major piece and the lance, 2. Promote the bishop and the rook, 3. Exchange the promoted lance with the gold. After that we use the same plan as in the 9-piece handicap: 4. Take the handicap giver's gold by a cooperated attack by the dragon (promoted rook) and the horse (promoted bishop), 5. Force the king to the corner, 6. Checkmate the king. Just because our opponent has only a few pieces, it doesn't mean that any attack will be successful. It's very important to have a plan and to know what goals have been already achieved and what should our next aim be. 2 ７六歩(77) ( 0:00/00:00:00) *The basics are the same: we start with P76 and aim at activating the bishop. Just by moving a single pawn, we make the bishop aim at the opponent's camp. 3 ７二金(61) ( 0:00/00:00:00) *The handicap giver uses the golds to the left and to the right. 4 ６六角(88) ( 0:00/00:00:00) *Just as in the previous game (9-piece handicap) we advance the bishop to the 66 square and aim at the left edge. 5 ８二金(72) ( 0:00/00:00:00) *Uwate plays G82 and prevents the bishop from promoting! This differs from the 9-piece handicap. Our bishop aims at two squares, 93 and 33, but they are protected by the two golds, so the bishop cannot promote. We increase the number of attackers from here. Hint: We attack on the left edge. Let's start with a pawn. 6 ９六歩(97) ( 0:00/00:00:00) *I recommend this move for you to learn. * *There are many players who want to attack as fast as possible and advance the left knight, but if we think about what's going to happen many moves from now, activating the lance is a good way of thinking. 7 ７四歩(73) ( 0:00/00:00:00) 8 ９五歩(96) ( 0:00/00:00:00) *We advance the pawn. 9 ６四歩(63) ( 0:00/00:00:00) 10 ９四歩(95) ( 0:00/00:00:00) *We advanced the pawn very far and now it's attacking our opponent's pawn. If Uwate ignores this move, we will create a promoted pawn (tokin). 11 ９四歩(93) ( 0:00/00:00:00) *The handicap giver has taken the pawn. * *What's our next move? * *Hint: * *Let's keep on attacking the edge! 12 ９四香(99) ( 0:00/00:00:00) *We recapture the pawn using the lance. Now, the pieces aiming at the 93 square are: Handicap taker: The bishop and the lance Handicap giver: The gold So we have the numerical advantage. 13 ９二歩打 ( 0:00/00:00:00) *I used a pawn in hand and dropped it. If the lance moves to 93 and promotes, then it will be captured by the pawn and we will lose material. * *Let's think about the next move. It's an extremely important move the 8-piece handicap. * *Hint: * *We would like to add yet another attacker to the 9th file. Which piece should we use? * *There is a very important piece, that we still have not used. 14 ９八飛(28) ( 0:00/00:00:00) *It's a great idea to use the rook in this way! By adding the rook to the bishop and the lance, we build up an attack made of 3 pieces. * *** Dropping the pawn to the 93 square is another great idea. 15 ５四歩(53) ( 0:00/00:00:00) *Let's break the edge! *What's the next move? * *Hint: * *If we move the lance to the 93 square then it will be captured by the pawn. 16 ９二香成(94) ( 0:00/00:00:00) *We take the pawn and promote the lance. Next, if the gold takes the promoted lance, then it would be recaptured by the rook. For the handicap taker, it would be a great success: he would both gain material and promote the rook. 17 ７三金(82) ( 0:00/00:00:00) *Uwate escapes with the gold to prevent losing material. 18 ９三飛成(98) ( 0:00/00:00:00) *Student M has promoted the rook and broke the edge. Our next goals are: * to promote the bishop, * to exchange the promoted lance with the gold. 19 ６三金(73) ( 0:00/00:00:00) 20 ８二成香(92) ( 0:00/00:00:00) *We use the promoted lance. 21 ６五歩(64) ( 0:00/00:00:00) *I threatened to take the bishop by the pawn. 22 ７七角(66) ( 0:00/00:00:00) *Let's calmly escape, there is no reason to rush. 23 ４二玉(51) ( 0:00/00:00:00) *I run away with the king. 24 ８三龍(93) ( 0:00/00:00:00) *We actively use the rook and make a combined attack with the promoted lance. 25 ６二金(63) ( 0:00/00:00:00) *Next we would like to use the bishop. 26 ９五角(77) ( 0:00/00:00:00) *Ms. M has attacked the gold using the bishop. It's a great move. * *(checking the king by B86 is good as well) 27 ５二金(62) ( 0:00/00:00:00) 28 ７三角成(95) ( 0:00/00:00:00) *We made a horse. * *We managed to promoted both major pieces so let's exchange the promoted lance with the gold next. 29 ３四歩(33) ( 0:00/00:00:00) 30 ７二成香(82) ( 0:00/00:00:00) *We move the promoted lance closer to the gold. 31 ３三玉(42) ( 0:00/00:00:00) 32 ６二成香(72) ( 0:00/00:00:00) *We try to exchange it with the gold. * *If Uwate takes the promoted lance, the gold with be recaptured by the horse, so Shitate will gain material. 33 ４二金(52) ( 0:00/00:00:00) 34 ６三馬(73) ( 0:00/00:00:00) *We move the pieces closer and closer. 35 ２四玉(33) ( 0:00/00:00:00) *An early escape by the king. 36 ５二成香(62) ( 0:00/00:00:00) 37 ３三金(42) ( 0:00/00:00:00) 38 ５三馬(63) ( 0:00/00:00:00) *We put more and more pressure on the opponent's pieces. 39 １四歩(13) ( 0:00/00:00:00) 40 ４二成香(52) ( 0:00/00:00:00) 41 ２二金(32) ( 0:00/00:00:00) *Ms. M had a chance to play a good move here, but in the game she tried something else. Hint: How to make good use of the promoted lance? 42 ８二龍(83) ( 0:00/00:00:00) *This move aimed at the gold on the 22 square, but attacking the gold by +L43 (promoted lance to 43) was better. #Branch: +L43 - #44526 43 １三玉(24) ( 0:00/00:00:00) 44 ４三成香(42) ( 0:00/00:00:00) *Pulling the promoted lance was just a bit delayed, but... 45 ２四金(33) ( 0:00/00:00:00) *The handicap giver was given time to make an escape route for the gold. 46 ３二成香(43) ( 0:00/00:00:00) *We attack the other gold. 47 １二金(22) ( 0:00/00:00:00) *I run with gold, but there is a decisive move. * *Hint: * *Make the king unable to escape. 48 ３一馬(53) ( 0:00/00:00:00) *This check decided the game. Uwate has no pieces in hand and the king has no place to run. 49 ２二金(12) ( 0:00/00:00:00) *I moved the gold and temporarily prevented the check, but... 50 ２二馬(31) ( 0:00/00:00:00) *It was taken by the horse and the king got check-mated. * *Ms M. has broken the edge and used the promoted lance really well. * *Please remember the technique of moving the promoted lance along the attacking lines of the dragon and the horse. I hope you can use it in your own games! 51 詰み ( 0:00/00:00:00) まで50手で詰み
