Tuesday Chess
Good morning, Tuesday! Yesterday saw the half-way point of the tournament, with round 5. Just 4 rounds to go! Things are heating up. Top seed Jobava went down in flames against the Indian GM Mhamal Anurag, rated some 200 points lower than the Georgian superstar, who now stands at 3.5 points.
gm Anurag – gm Jobava Portugal Open rd.5 (1-0)
As for my own game, I won an instructive ending against the Ukraine IM Borsos, putting me at 4 points. I present the game with some notes. Enjoy!

<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>My opponent sacrificed a pawn in the opening and I held on to it, even though the pawn itself held very little importance. In the position that has now arisen we have an interesting struggle between Queen and 2 Knights versus Queen and 2 Bishops. Black plans to play f5 to activate his Bishop on g7.</strong></span></div>
} 35.f5!{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Not just preventing Black’s plan, but trying to impose the two Knights over the two Bishops. It is well known that Knights are superior to Bishops in closed positions. Worse still, Black has no counterplay.</strong></span></div>
} gxf5{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Not an easy decision to take, as White now gains the f4 square for his Knight, but it is difficult to suggest better. Closing with g5 would allow the Queen to infiltrate on the Kingside with serious threats.</strong></span></div>

<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Hitting f5 and ‘observing’ c7. In superior positions of this nature, it is important to use multiple attacks, or attacking multiple squares, to tie down the enemy to a passive defence.</strong></span></div>

<div class="custom_attn_box" style="border: ffffff solid; color: 000000; background-color: ffffff; text-align: left;"><span style="color: #000000;"><strong>Knights need squares. Bishops need diagonals. So clearly White dominates the play.</strong></span></div>

<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>White intends to play his Knight to e6 and then capture on f5. Then with all of his pieces taking up advanced positions, real attacking chances will appear.</strong></span></div>

<div class="custom_attn_box" style="text-align: justify;"><span style="font-size: 12pt; color: #000000;"><strong>Black is doing the best he can, but now he does not have the Bishop pair. White now increases the pressure and begins to prepare for a transition to a Queenless ending. Black seems unable to prevent this for very long.</strong></span></div>
} 42.Nh5 Be7{[#]} 43.Kf3!{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000; font-size: 12pt;"><strong>White plans to advance his King to e4 before exchanging Queens with Qe6. Capablanca always advised to take your time in winning positions, slowly improving things and depriving any and all counterplay.</strong></span></div>

45.g4{[#]} Qh7{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Losing patience, but understandable. No body likes to suffer in vain.</strong></span></div>
} 46.Ke4 Qxf5+ 47.Kxf5 Kf7{[#]} 48.h3!{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Instructive. As zugzwang approaches White removes this pawn from a dark square and keeps a tempo in reserve (h4) when he should need it. The Black King can not move without allowing the White King to advance.</strong></span></div>

<div class="custom_attn_box" style="border: ffffff solid; color: 000000; background-color: ffffff; text-align: left;"><span style="color: #000000;"><strong>Finally White’s ‘useless’ pawn on d5 serves well to further Black’s problems. White has a clear winning plan in mind.</strong></span></div>
} cxd6
51.d5{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Any endgame connoisseur would recognize the ‘Good Knight / Bad Bishop’ theme. Helping White even more is the fact that all of Black’s pawns are split and on the same colour as his Bishop, reducing the Bishop’s role to caretaker.</strong></span></div>
} Be7 52.Nf4 Bd8 53.Nd3! Ba5{[#]} 54.h4{[#]
<div class="custom_attn_box" style="text-align: justify;"><span style="color: #000000;"><strong>Zugzwang! No matter what Black does he will soon lose a pawn. Resigning is now the most reasonable move, but Black decides to play on ‘for the spectators’.</strong></span></div>
