More winning 5-second tactics
Biting off more than you can chew…
gm Uhlmann, Wolfgang
im Raykhman, Alexander (2412)
Bundesliga Dresden 2015.3.15 Position after White’s 16th move (16.Nh4!?) A sharp position! White did not need to sacrifice his d-pawn (16.Nh2! h5 17.Rad1 with a small positional plus.) but preferred to complicate.
Now Uhlmann has two ways to take the pawn (immediately or as in the game). The first is correct: 16…Bxd4 17.Nf5! Bg7! with unclear play. Black’s Kingside is open, but the coming …Ne5 keeps things together. INSTEAD, Ulhmann got lured into thinking that he could prevent the Knight going to f5 by first attacking the Bishop…
16…Nb6?! 17.Ba2 Bxd4?!
Now if 18.Nf5 BxN!
This strong move was overlooked by Black. The threat is now 19.Qg6+ and if 19…Bxe5 (to intervene the Bishop on g7 should White give a check) 20.RxB! PxR 21.Qg6+ with a forced mate. Little better would be 19…e6 20.Bb1! is crushing.
Now 19.Qg6 is prevented and 19.Bb1 would allow 19…Rh8
The pawn is a hero! Among the threats is Nf5+ winning the Bishop. If 19…Bxe6 20.RxB! is crushing.
It is hard to find better…
20.Nf5+ Kh8 21.Bb1!
There is nothing to do. Staving off mate will cost atleast the Queen.
