Yaacov in Vegas
SM Yaacov Norowitz played some interesting games at the North American Open in Las Vegas. I have annotated three of his better ones, including two where he turned a difficult game into a draw by forcing perpetual check.
Yaacov Norowitz - Ilya Smirin [E60]
20TH ANNUAL NORTH AMERICAN OPEN/Las Vegas (3) 2010
Norowitz's favorite Anti-KID set-up, which places the Bishop at b2 to oppose the Bishop on g7, with the hope of eventually trading off that important kingside defender.
This is Black's typical tactic, using the pin along the long diagonal to easily recover the pawn.
Perhaps Black's idea is to close up the long diagonal as quickly as possible. The more typical equalizer is 9... Ncxe5 to encourage some exchanging of minor pieces.
This advance seems very compliant in allowing the exchange of Bishops. but it is hard to see how Black otherwise gets play against White's simple plan of Rd1 and Nd5. Black now builds up a strong attacking position behind his spearhead pawn.
Taking control of d5 but ceding d6.
Black suddenly has a strong kingside initiative and a sac at h3 or f3 seems in the offing.
Black's deadly threats force White to find a nice drawing continuation.
36. Qb3+ transposes
Alex Barnett - Yaacov Norowitz [B12]
20TH ANNUAL NORTH AMERICAN OPEN/Las Vegas (4) 2010
Black has emerged from the opening with a clear advantage due to his well placed pieces, control of light squares, and superior pawn structure.
One of those rare cases where it's better to break up your pawn chains and capture away from the center in order to open up a useful file which will help to mobilize his Rook for attack on the e-pawn.

Yaacov Norowitz - Siddharth Ravichandran [D02]
20TH ANNUAL NORTH AMERICAN OPEN/Las Vegas (5) 2010
A Reversed Slav, which is the sort of thing that is typical of Yaacov's quiet opening play.
White cannot leave the Knight at e4 indefinitely without handing Black the initiative. Necessary was 10. Nxe4 Bxe4 11. Nd2! Bg6 (11... Bxg2!? 12. Rg1 Bh3 13. Rxg7 Bxh2? 14. Bh5 would create a picturesque win for White.)
Black seizes a slight initiative with his kingside threats.
The best way to battle back is to open the f-file, otherwise Black's initiative gets too strong. White is now in trouble and must sacrifice a piece, but he keeps some initiative for the remainder of the game and is eventually able to force a draw by perpetual check.
15... Bxe4?! allows White a dangerous initiative along that opened f-file, though it may be that Black can survive after 16. Bh5!
Cautiously defending e6 from sacrifices. From here on out, Black plays very strongly to improve his position and make progress, but White keeps battling to make his task difficult. Though I don't know the situation on the clock, I assume that became a factor.
18. d5!? Qd7 19. Rd1 Qe7 20. Qc4 h5 21. Bh3 Rd8 22. Rd4 Rd6 23. Rf2 e5 24. Rdd2 Nh7 25. Qb4 cxd5 26. exd5
White gets his wish and is now able to force a draw by perpetual check.
46... Rd8! prevents the Rook incursion and keeps a winning advantage.
Black cannot escape the checks.
