That is everybody below masterlevel and who is not a prodigy. Failing by either overlooking important replies or by drowning in them. In general I believe that the ones who overlook possibilities are far better off than who drowns in them. Because an oversight happens sometimes but drowning always.<BR/><BR/>That shows why this position is such beatiful testcase. If I can develop a solve-strategy that helps me to find a reasonable move within 20 minutes, I have succeeded. But maybe special training is needed. I intend to find out.Temposchluckerhttps://www.blogger.com/profile/07977208394417444785noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-46911620497988836122007-02-17T18:27:00.000+01:002007-02-17T18:27:00.000+01:00"given the fact that you just dismissed the winnin..."given the fact that you just dismissed the winning line as giving nothing to white, my attempts will not be in vain for you either if I succeed"<BR/><BR/>I've only spent about 5 minutes on this position, which is way too short for such a complex position and I made a mistake dismissing Nb4 too fast (missing 1. Nb4 Qc5 2. Bxe6 Rxe6 3. Rxd7+!). I also missed Nc5 as a possible reaction. I cannot tell for sure if I would have played Nb4 if it was a game of my own, but I tend to double-check my calculations and look deeper if the clock permits this. <BR/><BR/>You can't expect me to really exert myself if it is somebody else's game and I was trying to make a different point which still has some validity, right?Frank Sträterhttps://www.blogger.com/profile/04319940604063653586noreply@blogger.comtag:blogger.com,1999:blog-10713928.post-85208397517913600282007-02-17T18:04:00.000+01:002007-02-17T18:04:00.000+01:00I don't have this problem in fact I tend to consid...I don't have this problem in fact I tend to consider very few moves and sometimes this is a problem I missed 1Nb4 Nc5 but it doesn't look that good 2Qc2 and if he wants to save the queen he has to go 2Qa4 3b3 Qa3 and his queen is horribly misplaced while yours is now in a nice position lined up with his king maybe 4Bxe6 works(removing the defender of the f5 pawn)but this has to be calculated.After Nb4 Nc5 Qc2 he can try gxf6 Nxc6(Bxc6 Bxe6 and the f4 pawn falls with check)and Rxg2 white seems to have quite a few good options in response Qc1 Qb1 Rd2 and black's attack doesn't look dangerous.And Nb4 Nc5 Qc2 Qxf3 seems to also fail even if the e6 pawn is now defended since you can sac a piece to take the e pawn and then take the f5 pawn with check.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10713928.post-70858808028566756222007-02-17T17:32:00.000+01:002007-02-17T17:32:00.000+01:00I have a tendency to keep all options open.

A forced drawing line could be the way out.<BR/><BR/>3. tactics: black might sac the queen on f3 and then play gxf3 followed by f2#. Which move will prevent this mate? h4! and the king escapes to h3.<BR/><BR/>I actually started by looking at Nb4 attacking the queen, just taking one sensible forcing move and only then realized black's threats.<BR/><BR/>Only after this type of positional pre-pruning, I start calculating concrete variations:<BR/><BR/>1. Nb4 Qc5 2. Nd3 Qc6 draw?<BR/>1. Nb4 Qxf3 etc<BR/>1. Nb4 Qc5 2. Nd3 gxf3 etc<BR/><BR/>Concluding that it does not give white anything I start looking at other moves<BR/><BR/>1. Bb5 this might be the one, stop here and first look at other moves.<BR/><BR/>1. Ne5 nothing 1. Nf4 nothing 1. Bxe6 nothing<BR/><BR/>and only here I really dive into the calculation of 1. Bb5<BR/><BR/>For me this method comes natural and I am not sure how I learned this. I think it comes close to "playing with the position" first when I am in my "zone". In this position I found myself thinking along the lines: if black can move a couple of moves, which would be the best? Answer: 1.Qxf3 gxf3 2.gxf3 + f2# mate as an fantasy double-move.<BR/><BR/>I hope you will post the actual moves soon. I would like to know how you got the winning position.Frank Sträterhttps://www.blogger.com/profile/04319940604063653586noreply@blogger.com
