{Bohemia has a rich history of hosting great attacking games and players:
Alekhine played in Podebrady, 1936; Tal (Prague, 1960 - granted this was a
radio simul, and maybe Tal wasn't even in Prague); Uhlmann (Hradec Kralove,
1979); Shirov (Pardubice, 1994). The following masterpiece was played beside
the Elbe river in Pardubice, 2010 by the young master Anton Korobov.     Pay
special attention to how, from the very start of the game, Korobov:   1. gains
space;   2. Improves his pieces;   3. develops pieces,     all with tempo.} 1.
d4 d5 2. c4 e6 3. Nf3 c6 4. Qc2 dxc4 $1 {Intending to play b5 with gain of
tempo, gaining space on the queen side and clearing the b7 square, preparing
to put the bishop on the long diagonal.} 5. Qxc4 b5 6. Qc2 Bb7 7. Nbd2 Nd7 8.
e3 Ngf6 9. Be2 {The position looks quiet. But, in 3 moves, black will have a
rook on the open c-file and will open the long diagonal for his white-squared
bishop.} Rc8 10. O-O c5 11. Bxb5 cxd4 12. Qb3 Bd5 {Improving the position of
his bishop, and creating a weakness on e3/e4 - with tempo!} 13. Qa4 dxe3 14.

{White's in big trouble. He hasn't completed his development, his pieces are
not working together and his queen is stuck in the middle of the board.    
Black see this and launches a feroucious attack on the white king. His method
is simple. He moves his pieces closer to the white king.     Think like a
Grandmaster:   From the current position, visualize the position with black
pieces on Rc2, Ng4, f5, h4, g5 and the white queen on Qa4.} Rc6 {
Transfering the rook the Rc2, with tempo.} 21. Qa3 Ng4 {
The knight was not doing much on Nf6. Now it's attacking the king.} 22. Qb4 Rc4
23. Qe1 {White knows he's outnumbered on the kingside. He needs defenders on
the kingside so he transfers his queen to Qg3 via Qe1.} Rc2 {Black now has 3
pieces attacking the white king (Rc2, Ng4, Bd4) and white has just one
defender (Nf3). White is outnumbered on the kingside.     Notice all three
squares in front of the white king are under fire from black.} 24. a5 f5 {
The f-pawn joins the attack, supporting the g4 knight and preventing e4.} 25.
Qg3 h5 {Another attacker charges the white king.} 26. h3 h4 {
And he's intent on getting to the king. (Taking the pawn leads to mate)} 27.
Qf4 {Another!} g5 28. Qa4 {Black pushes the queen away from the kingside where,
once again, white is dangerously outnumbered.    Which is black's worst placed
piece and how can it be improved? (Hint: There is one more black piece which
can join the attack.)} Rxg2+ {Why does black sacrifice his rook?} 29. Kxg2 Qc7
{Because he aches to bring his queen into the attack without losing time. The
rook is off of the battlefield - but the queen is now on.} 30. hxg4 Qg3+ 31.
Kh1 Bxf3+ 32. Rxf3 Qxf3+ 33. Kg1 fxg4 34. Bd2 h3 {An instructive final
position. Black attacking the white king with three guys (Qf3, h3, Rf8) and
white defending with 0.} 0-1
