2. White to Move.  What would you play? What do you think about 1.Rf3?	3. White to Move.  What would you play? What do you think about 1.Rxf4?

STOP - Lecture begins below.

A rook is the second most valuable piece after the queen (not counting the 'priceless' king).  Just like the queen, it is a long-range fighter that can do a lot of damage.  Also, just like the queen, it can be an easy target, thus often prefers to operate from a safe distance.  It is rather clumsy in cluttered positions and can be attacked by minor pieces, pawns and even the king (this is something that the queen doesn't need to worry about.)

Recently, while reviewing games of one of my students, I've stumbled across several situations in which he 'issued wrong assignments' for his rooks.  Well, as I discussed these problems with him, I thought it might be beneficial to share the fragments with you.

First the materials and later then the draft of the lecture were sitting on my desk for a few weeks as I was very busy.  Finally, today, something happened that made me allocate time and finish the lecture.  That something was a blitz game on ICC.  Here is the fragment:

LionHeart (2600) - NN (2600)
 

A Black to move	B White to Move
After 1.Nc4xBe3.	After 1...Rd2 2.Re2 R2d3

C Black to Move	D Black to Move
After 3.Nf5+ Kf8 4.Nd4 Nd5?! 5.R1e1 Nf4 6.Re4+/-	After 6...e5! 7.Rxe5 R3xd4 8.cxd4 Nd3 9.Re3! Nxe5 10.dxe5 Rd2 11.Rb3! +/-

[Diagram A]  At the moment, Black has control over the d-file.  White is about to challenge Black via 2.Rad1.  So, Black ventured with his rook to d2.  Actually a harmless move as White has two alternatives.  I considered 2.Rad1 and, if Black takes on b2, White can force a draw.  2...Rxb2 3.Nf5+ Ke8 4.Nxg7+ Ke7 5.Nf5+.  I decided to play 2.Re2, keeping the Nf5+ trick for later.  Instead of trading, Black retreated - 2...R2d3.

[Diagram B]  And here, my opponent was unpleasantly surprised with 3.Nf5+ Kf8 4.Nd4.  Not sure if he immediately realized that his Rook was trapped (it was a Blitz game after all), but instead of preparing e6-e5 to free the Rook, he made a couple of pseudo-aggressive moves with the Knight - 4...Nd5?! 5.R1e1 Nf4 6.Re4+/-

[Diagram C] Now, if the Knight moves, White has Ke2 forcing Rxd4 with extra exchange.  Black found a way to escape only at the price of a pawn after 6...e5! 7.Rxe5 R3xd4 8.cxd4 Nd3, winning back the exchange.  After 9.Re3! Nxe5 10.dxe5 Rd2 11.Rb3! (11.Re2? Rd1+ 12.Re1 Rd2=), White was up by a pawn.

[Diagram D]  Compare the first diagram (A) vs. the last one (D).  White really did nothing spectacular, except a few defensive moves.  Black's loss is purely due to his 'active' rook play.

Now, let's get back to the three diagrams above from the games of my 1200 rated student:
 

#1 Black is down by two pawns, but he has a pair of bishops and fairly active pieces.  Still White has a solid advantage, no matter which of the many reasonable moves candidates Black picks - 1..Nxb2; 1...Rb8; 1...Nf4; 1...Bf5, etc.... In the game, Black decided to activate his rook and plugged it on the second rank - 1...Re2.  Well, White responded with 2.Ba6 and Black's attack was finished.
#2 White had a promising attack just a few moments ago, but allowed the trade of queens and left his knight without an escape square.  The best move here is 1.Nf5, getting a couple of pawns for the knight.  After 1...exf5 2.Bxd5, White has excellent compensation due to Black's compromised pawn structure. Instead, White played 1.Rf3 Kxh6 2.Rf6+ Kg7 3.Bf3.  Winning the h5-pawn wasn't sufficient; the rook on f6 is more of target then a threat to Black.

#3 Black’s last move was ...e5xf4.  White has several obvious moves candidates - 1.Qxf4, 1.Rxf4, and 1.gxf4, but they all are inferior at best.  In the game, White captured with the rook, but instantly regretted his decision.  After 1.Rxf4? g5! 2.Bxg5 hxg5 3.Rf5 Nh7, White doesn't have much for the bishop (only one pawn). White gets one more pawn for his bishop after 1.Qxf4? g5 2.Bxg5 hxg5 3.Qxg5, but it is not enough.  With 3...d5!, blasting White's pawn chain, Black should be able to convert his advantage.  1.gxf4?! runs into an unexpected 1...Nxe4! and, in spite of all the dangers, Black should come out from all these complications ahead by a pawn.

Thus, the best choice in this position is an intermediate capture 1.Bxf6, then capturing the pawn f4 on the next move.  After the balance is restored, White is at least equal.
