elohah: Notes to puzzle #14 in John Nunn's
Puzzle Book (Garcia-Smyslov; Sochi
This is a messy, MESSY puzzle, and
it is ENRAGEING to include it in
any puzzle book! (giving alternative
move to Garcia's 24 Bxa6?)
'1...Qa7 loses to 2 Rc7.'
No further comment here. Apparently
it is obvious that after 2...Re8,
that 3 Nc6? wins. Yet Black has
3...bxc6! 4 Rxa7+ Kxa7 with
sufficient material for the Q, indeed
one can go so far as to state that
BLACK is better here, with a strong
compact pawn mass, two potentially
very powerful bishops (notice White's
3(!) weak isolated pawns!) and moves
like ...c5 and ...f5 upcoming.
So it's 3 Qa4 then, right? (after
2...Re8) Doesn't that easily win a
piece? Yet Black has 3...Qb6!, when
after 4 Rxb7 Bxb7 5 Qxe8+ Ka7
6 Qxe7 Qxa5 7 Qxf7 Qe5 White also
doesn't have enough to crow about.
3 Qc4--? - trapping a bishop?
No, 3...Qb8! defends that. (Not
3...Kb8? 4 Nc6+! now wins.)
A final try would be 3 Bb5
This move seems to be the only real
winning attempt after some further
3...axb5 4 Qxb5 Qb8? 5 Rc4 wins.
3...axb5 4 Qxb5 Rg8 5 Rxe7 Qa6?
6 Qxa6 bxa6 7 Rxd6, White will win
with Rb6 followed by Nc6.
Or 5...Qc5 6 Qa4 Kb8 (6...Qa7 7 Rxd6
f5 8 Qb5 overwhelms b7) 7 Rd4!
(On 7 b4?, Black has the annoying
7...Rxe4! as a response) and the
winning Rb4 is unstoppable.
