Although  Alexandre's posts are always for me very interesting he seldom or
never posts the move sequences until asked. It would also be nice if the source
was included as to who played the game.

The above is an example of black being in a bind and eventually running out of
moves. Two possible quick lines are:

A. 1. Qxe5 fxe5 2. Rf1 Qe7 3. Bd1 Rc7 4. Bb3 Rc8 5. Rf7 Re8 6. Bd5 b5 7. b4
a6 8. Kg2 a5 9. bxa5 b4

B. 1. Qxe5 fxe5 2. Rf1 Rc7 3. Bd1 Re7 4. Bb3 a5 5. a4 Qc8 6. Bd5 Qb8 7. b4
axb4 8. cxb4 Qd8 9. a5 bxa5 10. bxa5 Qb8 11. a6 g5 12. Kg2

The moves above will show the general theme but there is no doubt an accurate
sequence of best moves that Alexandre will eventually post.

The most curious thing about this particular post is the heading
" ... that Junior 6 don't find!!" Why single out Junior6 with double exclamation
marks? Anyone familiar with how computers play will know that they
won't spot these long range themes.
