![]() ![]() ![]() I know this is unrepresentative of a real-life situation, which you would seldom face anyway, I feel that this is a good way to show you the ideas behind the technique. For simplicity reasons, I will show you as white checkmating black, with a light-squared bishop and all pieces on their normal starting squares. This example shows a relative idea of what both sides are trying to achieve. it is an extremely rare occurance to face this ever in real-life, but it's quirky! Once the enemy king is on the edge of the board, the h-file (or a-file), then it's relatively simple to force him into the corner and achieve checkmate, the hardest part of this is getting the king to the h-file in the first place, using just minor pieces it is pretty tough. The general idea for white is to initially keep the king and bishop close together to block off certain squares, then use the knights to block off other squares, so the enemy king only has 1 or 2 squares he can access, with both of them leading to the edge of the board! It's sort of like a tag-team between the pieces, like an airlock - allowing access to a particular square, cutting off the previous access points, then opening up a controlled route out, then sealing the king in, and repeating this sort of process. Both come in grey-red colour though, I had to put a dye on mine. This is not easy to do, when I try and do it I fail much more than I succeed, but that's because I'm not a GrandMaster!! To avoid checkmate, (just like in my previous blog post ) black will try and stay as close to the centre as possible, and avoid the corners like the plague! One is the Brutal Executioners which you can get from the Cosmetics Vendor (I think) on fleet, the other is the Fortified Electrum which you can get on the GTN for a little less. The following example shows how to checkmate using 2 knights and a light-squared bishop, with your king aswell of course! I'm showing you with a light-squared bishop because for me, it seems it is the only way I can apply the technique, but I know it can obviously be done with a dark-squared bishop, but when trying to do it over the chessboard, I can only do it with a light-squared bishop. ![]() Note how with a dark-squared bishop, ALL the white pieces are on dark squares. If you have a light-squared bishop, the checkmate position looks like this: So if you have a light-squared bishop head to a light-squared corner and if you have a dark-squared bishop head to a dark-squared corner. if you have a light-squared bishop, you can ONLY checkmate by force in the top-left and bottom-right corners, if you have a dark-squared bishop, you can ONLY force checkmate in the top-right and bottom-left corners. Still to this date I have not mastered the technique, even though I discovered the following technique myself, I am not sure at all if it is theory, or if there is a hard and fast definitive solution like checkmating with 2 bishops (see my previous blog post ) but my curiosity got the better of me, and discovered that checkmate can be forced in any of the 4 corners, but it depends on what colour-squared bishop you have. Now this a tricky one! You cannot force checkmate on an empty board with just 2 knights, but you can if you have a bishop to help things along. ![]()
