I've just done those the first three puzzle from the tactics trainer yesterday.
all credit goes to this book actually :

Coincidentally I just finished watching Searching for Bobby Fischer a few minutes ago, apparently this Pandolfini guy's pretty good yeah?
I did the first few and you seem to like the queen sac's, but who doesn't :P
An alternative solution to puzzel 3 is 1. Bxe7+ Kg8 2. Qd8#
An alternative solution to puzzel 3 is 1. Bxe7+ Kg8 2. Qd8#
yeah, thats the alternate, check the move lists to see if there is the alternate there :)
sorry, but part three will be shortened (maybe, but most likely) to puzzles 39 - 50
just a fun puzzle:
I love these puzzles. thanks for giving us these.
one suggestion, por favor: if it's 'black to move', then put black at the bottom. why would I try to move towards myself?...that's what therapy is for.
:D
