At this point, we try to merge them together. Perhaps there is some <b>combination</b> of the two sequences that will work. That is the essence of discovering <b>COMBINATIONS</b>!<br /><br />If we try 1. ... Nag3 first, then there is the threat of MATE with 2. ... Ne2 AND an immediate CAPTURE of a Pawn A-N-D the THREAT of taking the WRf1 AND the discovered attack (THREAT) against the WQd3. That is extremely FORCING and the very essence of a <b>combination</b>!<br /><br />The discovered attack on the White Queen, coupled with the other threats, overload the defensive capabilities of the White Queen. Obviously, the White Queen must move out of attack, or some other piece must deal with the discovered attack. <br /><br />2. Nxf5 takes care of the direct threat to the White Queen. However, now the mate threat is applied: 2. ... Nxe2+ and White is forced to play 3. Qxe2, allowing Black to pick up the Queen with 3. ... Nxe2, with a safe exit route for the Black Knight back out of the position. <b>Count up the material and Black is ahead.</b> <br /><br />The alternative counter is 2. Qxg3, moving the White Queen out of the discovered attack from Bf5 AND countering the mate threat. But now an alternative appears: 2. ... Nxe2+ 3. Kh1 (forced, because there is no White piece to capture on e2) 3. ... Nxg3+ 4. fxg3. <b>Count up the material and Black is ahead.</b><br /><br />There is a reasoning process that will lead to the solution. I know in my case, I often "see" something significant as a "clue" but then get fixated on that ONE clue and then try to make something out of just that one clue. The difference in approach I've just outlined is to "see" as many different clues as possible, and then determine if those clues can augment each other. Often times, the key is to change the move order, or to meld the two together as one sequence.<br /><br />Maybe that's way too esoteric, but that's how I TRY to think about solving these problems. I don't always succeed, because I get too locked in to a preconceived idea of the solution BEFORE I've really looked hard at ALL the possibilities. That is definitely a thinking process problem that I have to remedy. For example,if I get locked into the thought that the problem is about mate, I will ignore the possibility of gaining material, and spin my wheels trying to force mate. THAT thinking error is usually responsible for lots of wasted time. Repeating (for MY own benefit), <b>THINK WIDE BEFORE DEEP.</b><br />Robert Coblehttps://www.blogger.com/profile/12427520849707914818noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-87432770466077312002016-04-28T20:37:17.156+02:002016-04-28T20:37:17.156+02:00PART I:

To the CCT hierarchy, Neiman adds in "mate patterns." These are "stock" mating patterns which should be understood fist and then memorized. The hierarchy then becomes (1) Checks, (2) Mate patterns, (3) Captures, and (4) Threats, applied in that order.<br /><br />The first "clue" is that Black is to move. I generally ignore anything the opponent could do when trying to get a "feel" for the overall position. As long as I have the initiative (and having the right to move first always provides a measure of "initiative" as long as the opponent is kept too busy (responding to MY threats) to force me to respond to his threats).<br /><br />The only CHECK that Black can give is 1. ... Nxe2+. That provides a clue, but (by itself) doesn't do anything really bad. The White Queen snaps it off, leaving nothing more for Black to do. To me, the crucial point is that something potentially important has been found for Black, but it cannot be applied immediately; it doesn't work in isolation from everything else.<br /><br />The next thing on the "list" is a stock mating pattern. I'm pretty sure that with all the tactical problems you have solved, you have seen the stock mating pattern of two Knights checkmating the enemy King: one Knight at g3 (g6) and the other Knight at e2 (e7). The "box" around the White King is almost completely closed (it can only move to h1), and would be closed if the Black Knight gets to g3.<br /><br />1. ... Nxg3 is also a Capture and it unleashes a Threat at the same time (2. ... Bxd3) against the White Queen. That <b>combination</b>is always important to investigate.<br />Robert Coblehttps://www.blogger.com/profile/12427520849707914818noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-81654765336222147772016-04-27T20:24:06.434+02:002016-04-27T20:24:06.434+02:00Of course we should be able to solve these positio...Of course we should be able to solve these positions in under 6 seconds, because they are <i>simple</i>.<br />Well, maybe under 30 seconds, let's not be to harsh on ourselves.<br /><br />In this blog I focus on my failures, and that always looks a bit ugly. But since it exactly shows what the problem is, I don't care how it looks. I'm sure everybody has his own ugly failures.

Right now it's suppressing the rating. Also later when you try to solve fast again, you'll think "hey, look - my rating's skyrocketing, I must be improving really fast!" <br /><br />Stanislaw Ulam had a theory that recall from long-term memory works like a pack of dogs, all hunting for a buried memory in parallel. I wonder if solving chess puzzles is a short-range version of that. When a line of thought sees the King or Queen, it barks really loud. When it meets up with another line of thought, they sniff each other and then both bark. Eventually the crucial pieces and squares are made clear with all the barking. I doubt solving a puzzle will ever be a purely logical, algorithmic process, at least for me. <br />- mfardalAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-10713928.post-58763931096674150902016-04-27T19:04:30.341+02:002016-04-27T19:04:30.341+02:00I work in blitz mode.

An overloaded mind starts to overlook things. That is what happened in this case. A confused mind can see a 1400 problem as were it a 1900 problem.<br /><br />In theory the remedy is simple: find a method to ignore the irrelevant interactions.Temposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-47037679350864146692016-04-27T15:42:36.796+02:002016-04-27T15:42:36.796+02:00I usually try to CREATE somehow reasonable a good ...I usually try to CREATE somehow reasonable a good line and then try to find a refutation and then try to fix the refutation...<br /><br />In the End a solution to a tactical situation is the most forcing of the available moves.

A "Traped piece" is usually immobile and therefore quite often almost (temporarily) inactive.<br /><br />Strange how you look at the puzzle! Nxg3 threatens """mate""" by Nce2 and loss of the Queen by BfxQd3. Its an discovered attack and the discouvery is combinde with a """mate threat""" so ist a double attack too.<br /><br />More than 50% of the tactical puzzles at CT are King-related either "mate" or "mate-threat" or "exposed-king" so i think about the king first of all pieces<br />AoxomoxoA wonderinghttps://www.blogger.com/profile/16058687381216896080noreply@blogger.com
