For 29a 1...NxP you at least get something and save the rook and queen for now.
29b I like better. 1BxP if 1...Kh8 2BxR; if 1...Kf8 2Ne6+; if 1...QxB 2QxQ KxQ 3 Nd5 dis ch allowing a knight fork. :)

For 29a, 1...a5, then if e5 Ra6 frees the pin on the knight and saves him at the same time.

Mistake like I always seem to make. Not looking hard enough.

You've got 29a right Greg. Black has to play defensive against white's e5.
This actualy also threatens to pin the queen to the king, if black would for example play g5.

puzzle 29b has a better move for white.

Do you mean 2.Ne6 instead of 2.Nd5 (after 1.BxQ QxQ as ghorn suggested), or a different first move?

2.Ne6?? Nf5!

Ghorn's moves were correct upto Nd5, with discovered check, leading to Nc7 forking both rooks. But ... black would protect with Nc6 making the exchange come at a price.

White has a better first move instead of a (well found) fork setup.

For 29a I was considering castling queen side. That seems to accomplish the same thing as a6. Would this cause a problem?

Okay 1 Nxg6. Then follow up with 2 Bxf7. That should win a rook and pawn for a knight.

Nxg6 is indeed the correct move Ghorn :)
you might expect something like:
1. Nxg6 Nxg6 2.Bxf7+ Kh8 3.Bxe8 Nh4+ 4.Kh3 Qh6 etc. Whatever follows, black's king is exposed in the corner and black has a large enough material disadventage to just give up.


Steve, Black does indeed prevent e5 with 0-0-0, but white can launch a pawn attack, opening black's queenside.
If you ignore black's f4-pawn for a second and try playing a2-a4, you'll notice how feable black's pawns are standing on the queen side. The end result will look something like black's king hiding behind the (lone) c7-pawn, and pieces needed to protect the open queenside. They might come in better use attacking white's kingside instead.
Strong is playing Rb8, removing white's threathning e5 and using it for the pawn defense by making white's pawn attack useless, as white would now only open it for black, and go for the short castle.
