Tuesday’s winning 5-second tactics

——————————-
Najart,D (2150)

im Shirazi,K
14th Sautron Open 2014.10.30 Position before Black’s 25th move. White has ‘burned’ his Queenside in exchange for ‘dreams’ on the Kingside…If it were White’s move then he mates with QxB+! followed by his two Rooks invading on h8 and h7. All Black need to is play 25…e6! and White’s attack comes to a dead stop, as the reader can easily verify. INSTEAD, Black played what he thought was the same thing…
25…e5?

WHITE TO PLAY AND WIN!

Le Goff,R (2204)
14th Sautron Open 2014.10.27 Position after Black’s 28th move (28…e3). White has played a beautiful game so far, completely outplaying his opponent. Victory is within reach as Black’s Kingside is without any defence. Correct is now 29.Qb2!, lining up the Queen along the long diagonal. After 29…e2 (what else?) 30.Nh6+! and Black could give up with a clear conscience.
INSTEAD, White fell for a trick…
29.Bxe3?

BLACK TO PLAY AND WIN!
