I have heard that one of the most highly respected endgame books is Dvoretsky's Endgame Manual, although it is rather dry. Too dull for me... :? :oops:

For a) 1.Bxf7 Kxf7 2.Qc4+ wins as follows... 2...Be6 3. Ng5+ then 3...Ke7 4.Rf7+ Bxf7 5. Qxf7# or 3...Kg8 4.Nxe6 (threat:5.Ng5+ Kh8 6.Nf7+) Qe7 Nxc7+ wins an exchange (This could be improved upon...) 2...d5 3.Nxd5 then 3...Kf8 4.Ne5+ Kg8 5.Nf6+ Kh8 6.Qg8+ Rxg8 7.Nf7# (I like this one!) or 3...Be6 4....

I'll give 33a a wild stab in the dark... 1...Nb4 forces the queen away from defence of the pawn on g3 (2.Qe3?? allows Nc2 with the fork). This allows 2...Bxg3 followed by 3...Qxh4 forcing mate on h2 (or at least a lot of material for the prevention of that threat. Am I right, or have I missed the bi...

I didn't notice Bxg5. Let me start again.

1.g4 Bg6 2. Nxd5 wins a pawn as follows:

...cxd5 3. Bxd5 (exd5 loses to Qxe7#) wins the pawn.
...Bxg5 3. Nxg5 cxd5 Bxd5 wins the pawn.

1. Nxd5.

if ...cxd5, Bxd5 wins a pawn as exd5?? loses to Qxe7#

if ...Bxf3, Nxc7+ wins.

There are many ways to play the Philidor, but lines including 3...Nd7 and 4...Nd7 contain many traps.

I must agree with Pe. A secondary rating is a good idea, and it allows a fair representation of playing strength. The only possible problem is that the average playing strength of players on this site is over 1500, in which case ratings will be deflated, or below 1500 in which case ratings are still...

Why can't black play 3... Bxf3 ? After 4. Bxf3 Qh3 5.Be2 f3 Black appears to have an advantage... 5. Ke2 Re8+ is no better, as white can only stop promotion with 6. Be3 which leaves black a bishop up after fxe3. I'm sure I've missed something here... OH! :roll: :roll: :roll: :roll: :roll: :roll: :ro...

I was mainly to make the rook move. I came up with the position when I was playing a game against myself to test an opening (1.e4 c6 2.e5 d5 3.f4). When I was doing it, my goal was to win the pawn on g2. By attacking the rook I hoped to overwhelm the defenses by forcing the g1 rook away. I did see t...

For the first part, 1...Bb2+ 2. Kb1 Ba2+ Kxa2 doesn't help black at all. (well done keith).There is no way for black to give check so he must defend the now unguarded e6 square, but unlike above he is now a knight for two pawns down. As far as I can see, 1... Bd4 is not a good move. Why? White can p...

Yes White can reply in many ways, but the best two are probably 2. Nf8 or 2. Nc5. 2.Nf8 was explained above, so here is what happens with 2. Nc5 2. Nc5, but after 2... Rxe4 if 3.Rxe4 then 3...Rc1++ if 3.Nxd7 then 3...Rxe1++ so the only alternative is Nxe4. This leaves Black a pawn up, although White...
