Lesson 1

Very basic, but a good lesson for a beginning player. Nice! :)

Lesson 2

By the way, Ng7 is also an acceptable move, but I could only allow one answer.

Yes, these were copied from chess mentor, but once you use up all your hours, you cannot do more.

Very nice. I liked the second lesson, I will have to remember that one.

Thanks.

gd

good lessons. very helpful for those who want to learn. keep em' coming...

great puzzles and lesson very helpful!

1. Ra8+, forced mate in 3. All of these puzzles are taken from free chess mentor lessons.

On puzzle three, 3. Qd2+ wins the rook with a fork.

ShiViChess, you probably have good intentions, I suggest putting in some time to try to grasp these diagrams yourself before you post them as lessons.

ShiViChess> Lesson #3: { Hope seems lost. Black could easily play Rh1#. How can white keep from losing?}

Always look at checks and captures. White has at least four saves:

1.Qd4+ Kg8 2.Ra8+ (2.Qxf2 also wins easily) Re8 3.Rxe8#

   (1...f6 2.Qxf6+ Kg8 3.Qg7#)

   (1...Re5 is hopeless)

1.Ra8+ Kg7 2.Qg5#

   (1...Re8 is hopeless)

1.Qxf3 (goodbye Rh1#)

1.Nxf7+ (the trickiest to play) Kg8 2.Nh6+ with mate to follow.

   (1...Kg7 2.Nh8+ Kxh8 3.Qd8 Re8 4.Qxe8#)

          (2...Kh6 3.Rc6+ Kg7 4.Qd7+ Kxh8 5.Ra8+ Re8 6.Rxe8#)

ShiViChess> 2. Ne5+ { The knight is moved to safety, and uncovers a check.  } 

Q+R form an easy mating net. The knight's safety is irrelevant. A win is a win no matter how few or many pieces are left.

ShiViChess> 4. Qg6+ { Yet another check. The queen cannot be taken because of the knight.  }  4... hxg6 { The only legal move is hxg5.  }  5. Nxf3+ { The knight forks the rook and the king. If the king is attacked, the king can move.  } 

The queen sac serves no purpose. You could've immediately played 4.Nxf3 and won his rook without sac'ing your queen.

ShiViChess> 17. Nxg5 { The knight is gone. White has virtually won.  }

White was won in the initial position. Ok, let's look at the positives. You were able to convert a queen-up ending in 17 moves. That's actually a great start. But next time, try to consider all CHECKS and CAPTURES. In many cases you found a move that didn't toss the win, but wasn't nearly the fastest or easiest win.

good but lots of people know that one all ready :)

Puzzles #1 and #2 are fine.  I finally switched to the move list on #3.  17 moves?  As pointed out, Ra8+ wins in three.  Qd4+ wins in four if Black throws the Rook and Pawn as delaying sacrifices.

Always win as fast as possible.  A complex 17 move combination is in no way sound if mate in three is on the board.  You give yourself too many chances to slip up and throw it away.

Presumbably Black will resign after Ra8+ (best) or Qd4+ (next best, and the first combination that I looked at:)), because they will suddenly see that it is over.

hey those puzzles are in the chess mentor right?

i don't like lesson #3. it's not straight forward.

Lesson 3

4. Nxf3 avoids the queen sac
