Darsniek

Misha Tal
Position after White’s 22nd move. From a tournament in Riga, Tal’s hometown. The future world champion was just 14 at the time and already you could see that he loved to attack! Here his g4 is a bit too loose. On top of this, White has aligned too many of his best pieces along the h1-d5 diagonal…this gives motif for a vigorous counter attack by his opponent.
BLACK TO PLAY AND WIN!

Petrov, Vlad
Moscow, 1940. Position after White’s 40th move (40.Kg2). The position is wild , but White’s King position is a serious cause for concern. Unfortunately for Black, in his rush to make his 40th move (time control) , he decided to play it safe: 40…Be7? and after 41.Nxf7! Petrov found himself forced to go into a much worse ending, which the future world champion did not fail to win.
HOWEVER, in the position above, Black has some surprising resources, albeit not easy to find!
BLACK TO PLAY AND WIN!

Tal Mikhail N—Darsniek: Black crashed thru with the spectacular 22… Rxd5! 23.exd5 Nd4!! 24.Qd1 Bxd5+ 25.Kf1 Bc4+ 26.Kg1 Nf3+ 0-1
Smyslov Vassily–Petrov Vladimir : Black has a winning attack after the deflecting 40…Bc5! , when there is no good defence. If White takes the Bishop with 41.Qxc5 then 41… Qxe4! Is crushing: 42.Nc6 ( 42.Qc6 Nh4+ or 42.Kg3 Qf4+ 43.Kg2 e4! 44.Qd5 exf3+ 45.Rxf3 Nh4+ ) Nh4+ 43.Kg3Qf4# ; No better is 41.Re2 Nh4+ 42.Nxh4 Rg1# The most principled defence appears to be 41.Rf1 when Black must find 41…Rc1!! .Then would follow 42.Rxc1 ( Useless are 42.Qxf7+ Qxf7 43.Nxf7 Nf4+ or 42.Nxf7 Nh4+ 43.Nxh4 Rc2+; or 42.Qe2 Qf6! with Nf4 threatened ) 42…Nh4+ 43.Nxh4 Qd2+ and it is all over.
Hi, look at the combination in the game Nasanjangal-Firat from World Junior round 8. I’m amazed.
