This move is gets an "!" from IM Dimakiling. Rhal has previously played 7.Be3; vs Alfonso in PACE Elims, April 2010. NM Cabelon recommends 7.a4 to prevent b5, then Na3-Nc4.
Controlling the center is important because it allows one to create more effective threats and the opponent who is trying to play on the flank will be compelled to turn his attention to defense. Yakovlev in Planning in the Middlegame

According to NM Giri, the plan is still d4. With c4, "nawalan na nang pawn break ang White and allowed Black to control the d4 square and gave Black's B a longer diagonal."11... Ba6 12.Rb1 Nb6 13.b3 e6 14.Bb2 Nd4 15.Nxd4!

ReplyDeleteNM Marlon Bernardino analyzes this game with Rhal. He pointed out the ff:
1) the need for a4 in the opening to counter the thematic pawn-roller by Black
2) that pushing the c3 pawn to a4 is a mistake for it opens up the diagonal for Black's fianchettoed B

ReplyDeleteNM Gerry Cabellon also analyzes this game with Rhal and pointed out the ff:
a) to play a4 instead of h3 in order to control the b5 square and freely post a N at c4.
b) White's N must immediately occupy c4, thus instead of Bf1, better is Nc4, then Qc2
c) the c4 push wasted the move c3 and it cedes control of the d4 square to Black who can post a N there. It also deprives White the chance to play the d4 pawn break.
d) Black's Nc5 which attacks d3 and b3 and similar positions must be avoided
White's 7th move,h3,wasn't bad at all. The plan was to prevent Black from playing the annoying move,Ng4,after developing the Bishop to e3. 8. Re1?-White must be consistent with his plan; after 7. h3, he must proceed with Be3 then Nbd2. Black's b5 on the 8th move was premature, it would allow White to get back into the scheme of the game with d4 but unfortunately White missed it. 9.d4 b4 (9...Nxe4? 10. Bxb5+-) 10. e5 dxe5 11. dxc5 favors White.
ReplyDeleteGM Bong, Thanks for your input and continued monitoring of Rhal's games. God bless.
