Puzzles needed for tactics trainer

Corrected by shoopi, my last puzzle stands like this:

shoopi pointed out that the Rook at h6 could make the Rook's discovered check forced and removing the pawn from d5 really finishes all other chances; black can't defend the Bishop's check with that pawn anymore.

Thanks for the correction, shoopi.

katonas, you have the puzzle now.

Thankyou edvinj,

Black's 48th http://www.chess.com/echess/game.html?id=30031245

81st puzzle http://www.chess.com/tactics/server.html?id=426763 

Unfortunately  http://www.chess.com/echess/game.html?id=41809413   can't continue beyond move 17 so it isn't conclusive enough.

Black's 38th puzzle, unfortunately it can't continue beyond 1 move

continuation puzzle from above

82nd puzzle http://www.chess.com/tactics/server.html?id=295219 

For the last game removing the c4 pawn removes any ambiguity, and the puzzle is conclusive as you said.

83rd puzzle http://www.chess.com/tactics/server.html?id=272583

Hi katonas, that's a very nice variation you found in

http://www.chess.com/tactics/server.html?id=295219

I guess the Rb3 move must be very hard to find.

From reading your post I am not sure you looked at my original submission correctly though. I was thinking of starting it one half move later, and seeing it from whites perspective. Or perhaps you just thought the c7 move was just to trivial. Anyways, thanks for adding the problems.

Perhaps this might work. Haven't checked it with an engine...

I will post the game as soon as possible. Meanwhile here is another one:

Please bear in mind that the grades are ecf!

The puzzle was ambiguous with Qc1! a winning alternative to c7. Please use an engine to check for alternative winning lines when submitting puzzles.

Unfortunately I don't think this puzzle is conclusive enough to make it into a TT problem.

The original problem could be made unambiguous by removing the e5 pawn but as you said, e7 isn't very challenging.

Thankyou hessmaster (kirtley game)

Although this is a nice example of this tactical motif I'm not sure if I can approve this problem. I shall ask another approver.

Approved

84th puzzle http://www.chess.com/tactics/server.html?id=317781 

Metaknight 251 the puzzle has multiple alternative winning lines and so is ambiguous. 

Strategic play (self composed problem) - there are several moves stronger than 2.Qg7+ after 1...f5. Mate isn't forced as after 4.Rg6+ d4 only gives white a +3.27 advantage

Please note I'm being very strict regarding alternative advantageous lines. I will reject even a mate in 1 move if the next best move is given a value above +1 , or mate in any number of moves by an engine.

Potential .. just analysing the game:

[White "Lympathy"]

[Black "bharatkumargupta1"]

[Result "1-0"]

[FEN "1k1r2nr/1p1qb1p1/4p2p/1P1p4/1Q1P4/5NP1/2P2P1P/R1B2RK1 w - - 0 19"]

katonas, 

I posted an edit (post #275) after the original one, to remove the d4 variation and even force Rg6+.

Please check that if you haven't yet.

If required, I'll delete the original one.

StrategicPlay, 

2.Qg7+ (mate in 4) has 2.Re1 (+4.88) as a winning alternative

5.Bxf6# has Rxh6 (+7.97) or Rxf6 (5.51)

However the 2.Re1 line provides a tough problem

removing the f2 pawn makes Qxg7 less advantageous...

Does this approved?

Wow, katonas. You turned it into an entirely different thing.. 

nyLsel, your puzzles are quite good. They mostly deal with endgames with LOW material for either side but still a decisive result. 

theskyisblue808, http://www.chess.com/livechess/game.html?id=316024991 31.d6 is too easy a first move, and also has 31.a5 (+2.29) as an advantageous alternative.

Thankyou Spieler999 for two unambiguous lovely puzzles which needed no editing,

Your sideline from one of my games is fascinating

87th puzzle http://www.chess.com/tactics/server.html?id=71317

Its ok to use bxa4? as a linking move to allow your 2nd and 3rd puzzles to be together.

Thankyou Justified08,

Gwilym puzzle 1 was ambiguous, however a sideline provided a puzzle

91st puzzle  http://www.chess.com/tactics/server.html?id=442547 

Thankyou nyLysel, the g pawn can promote into a queen or bishop so unfortunately your last problem has to start later. You could always post the full puzzle in a comment under the TT puzzle.

post on my WALL  

katonas, I want to thank you for all the hard work you put up for this to make TT better for all of us

Really, your effort is well appreciated!

Here's another fantastic tactic from one of my games (this is it for me, unless I compose or play more games here on chess.com =)

shoopi, you're welcome. Thankyou to you and all the other submitters for their submissions, and patience.

I had to alter puzzle one as Bg6, and Kh8 were alternatives to Bf5, which meant the puzzle had to start with the bolt out of the blue. I shall ask another approver what they think of the puzzle as it is quite complex.

I love the variation 93rd puzzle  http://www.chess.com/tactics/server.html?id=167253
