  • Tactics corner - puzzle 50

    The previous puzzles dealt mainly with king safety and how this information is prevalent over the other. Of course slicing the information (if we want to label them, cause e.g it helps us when things are categorized) can be done in infinite number of ways but we now should know that most of the times there's critical information we should look for. You also developed (if you actually tried to solve them) a bit of other skills, like using the information about your opponent against him (his picture of chess to target his weak spots), plan-development and tactics. Now that we know how safe is safe, let's focus on how active is active. Of course the amount of information in any given chess position is far greater than this, but this time activity is the prevalent factor. Or is it? And btw, if anyone cares to proceed, which I hope, setting up a board or using any software reading fen strings is a must. So is understanding previous excercises, as now we level up a bit. gl & hf!

        Well at first I'd say Nxf5 is good. It doubles black's pawns thus weakening d5. It also makes e6 possible in some variation.

        But I think 1.g6 is the key move as black can't play Ng3 forking. Ng3 wins the exchange but gives white a huge attack in my opinion. Lines like 1.g6 Ng3 2.gxf7+ Kxf7 3. Ng5 Kg8 4. Qg4 Nxf1 5. Rxf1 give white good prospects on the kingside.

          Nxf5 should be considered last, since, although you do kill black's only active piece, you do that at the cost of your own thus reducing your own firepower. In short we say that if you're attacking (or have an attacking position), you don't want to exchange pieces, as you help an opponent with the defence.
          Nxf5 exf5 and now:
          if g6 then Nf6 if h6 then g6 and if Qg2 then g6 and no more attack. Nh4 doesn't help much, d4 is also weak; knight will relocate to b8-c6 given time.
          g6 first is better, but now the knight dies and we end up having not enough firepower again:
          1. g6 Nxe3 2. fxe7 Kxf7 3. Ng5+ Kg8 4. Qxe3
          The idea that Ng3 doesn't work is a key to this puzzle though, so you're a few steps closer.

            When I said (post 2) I was not talking about blacks fork. My NxN was to prevent blacks Nh4 after whites g6

              Black has no invasion in this position.

                If an immediate g6
                1. g6 Nh4
                2. NxN QxN and the black queen enters white's king's area.
                OR
                If white does not take black's knight on move 2 Then black plays N(h4) xN(f3) and whites kingside is vulnerable to the entry of black's queen.

                    I know what: please focus only on Ng3 response. I claim it still backfires, please show me how. You have the first move, but usualy there are more fireworks in such positions. After that we can examine what black should do instead of Ng3.

                      If an immediate g6 then Black can play Nh4 and his queen enters white's king area. If white does not play Nxh4 then black can play Nxf3 and once again the black queen enters white's kingside.

                          I do admire your spirit, but it's bringing a knife to a gunfight:
                          1. g6 Nh4 2. gxf7+ Kxf7 3. Ng5+ Kg8 4. Qg4 Nc5 5. Qxh4 h6

                          EDIT: or 5. h6 from white as a good alternative move.

                            I used an engine to take over the game after the sequence you proposed, and still, after a while, black manages to endure and use the queenside to attack white and force queen's exchange, then use the extra material to wipe out the leftovers. Either the engine is not that good to plan a strong attack for white before black manages to do this, or maybe white's perspective is very very optimistic here...
                            Don't drive faster than your guardian angel can fly.

                              I'm confused. Why 4...Nc5?? Why not 4...Nf5! It seems to me to hold for black.
