From the top board in the 4th round of this year's BC Open is a game between two masters who manage to make an Exchange Slav exciting! A cursory glance might lead you to believe that White led the whole way, and, while true to some extent, Black had an equal position at various points.

1. d4 d5 2. c4 c6 3. cxd5 cxd5 4. Bf4 Nc6 5. e3 e6 {It's somewhat uncommon for
Black to close his light-squared Bishop in this way.} ({much more common is}
5... Nf6 6. Nc3 a6 (6... Bf5) 7. Nf3 Bg4) 6. Nc3 Bd6 7. Bxd6 Qxd6 {This
position just seems really easy to play as White. Although the position is
relatively equal, it is always White who holds the edge.} 8. Bd3 Nf6 9. f4 {
clamping down on e5. The position can quickly become unpleasant for Black} a6
10. Rc1 Bd7 11. Nf3 Rc8 12. O-O Ng4 $6 {The idea behind this move is to play ..
.f5, but it seems somewhat suspect} 13. Qe1 f5 {Now, the White Knight has the
potential for a strong outpost on e5 since there will be no pawns to disturb it
} 14. Ne5 {Too soon} (14. Na4 {targeting the weak dark-squares. White doesn't
need to rush anything; his position plays itself} O-O 15. Nc5 Rc7 16. h3 Nf6
17. Ne5 {and something like Rf2-c2 will put Black in severe discomfort}) 14...

natural}) 23. Qa5 {White gains a tempo} Bc6 24. Nb3 g5 {Aggressive, but I
don't think this was the right time. White has a clear advantage on the
Queenside, but it's hard for him to make clear headway. By opening up his
Kingside, White may be able to take advantage on both sides of the board.} 25.
Qb4 Qe8 26. Be2 Rg8 27. Qd6 g4 28. h4 Rg6 29. g3 Nf7 30. Qb4 {The position has
closed up on the Kingside, so now White is the only one with any chances} Nd8

this move. I suspect Black just didn't know what to play. What he may have
missed is that it creates a weakness that can be attacked by White's Knight
going to f4} (34... Be8) 35. Qc3 Qe8 36. Nd3 (36. Qa5 {nearly winning. The
main threat is b4-b5} Qe7 37. b4 $18) 36... Rc7 37. Nf4 Rc8 38. Qa5 Kh7 {A bad
move but there weren't really any good options} 39. Bd3 $2 {Tanraj could have
put the game away, but he instead prolongs the inevitable outcome} (39. b4 {
wins almost immediately}) 39... Kh6 40. Qb6 Nf7 41. Kf2 $2 (41. Qb4 $1 {
threatening Qd2 and possibilities of opening up the c1-h6 diagonal with e4})

tempting, this actually lets Black get back into the game} (48. Qa7 $1 Qc7 49.

endings)}) 48. Qd6 Qa2+ 49. Ke3 $2 {White's advantage just dropped from +3 to 0

but White will be able to check on b6 at some point removing the pin} Bxb5 50.

impossible as well} 58. Qc8+ Kg7 59. Qxb7+) 58. Qb6+) 49... Be8 $4 (49... Qa5

are a number of ways for him to avoid the perpetual checks that Black attempts
to find.} Kh7 51. Qxe8 d4+ 52. Kxd4 Qd5+ 53. Ke3 Qf3+ 54. Kd4 Qd5+ 55. Kc3

Kh6 68. Qf6+ {An interesting game where White held the advantage in the
opening until a few inaccuracies gave Black equality. Black make some
questionable moves starting around move 18 only to give White his advantage
back. Tanraj then improved his advantage until reaching a winning endgame only
to nearly spoil the win with his 49th move. Thinking that his position was
already hopeless, the Black player missed a draw with 49...Qa5. The lesson:
stay vigilant until the end!} 1-0
