FBGs vs Kasparov- chess game- Draw agreed to (2 Viewers)

Just updated my board, which I had not done since the queen exchange or thereabouts, and great great job Tim and all.  Nice.  

Assuming I have the board right, the countermoves to his two possible rook moves seem pretty clear.  

The only other move I see for him is Bxa7, which he might consider expedient because it keeps his rook on the back rank, but the pretty obvious answer is Rxd5 there as well.  Doesn't seem to accomplish much for him versus Rxa7.  

Love the lines of attack against his king with our rook & bishop combo.  Hate his bishop & pawn pair on the fifth rank, preventing any advance on to b6, c6, d6 and e6.  

Nice job.  

 
Kaspy plays Rxa7+ 

Kaspy writes: "I fly home tomorrow so I'll be able to pick up the pace then. I haven't given a chess game this much energy in years! Being on vacation doesn't help!" 

I wrote back, "Thanks, that is a tremendous compliment to everyone involved in this." 

 
OK, we looked at Rxa7+ at length (though we looked at Rf8 even longer.) No matter what the variation, we all agreed that Kd8 is the next move here. So im going to play it. 

 
OK so I now see a problem with my proposed response to e6: 

e6 Rd2+ Ke1 e3 e7+ Rxe7 

earlier I thought he would respond with Rxe7. It he can simply play Ra3 (or Ra8+ Re8 Ra3) He wins the e pawn. 

So I don't think Rd2+ is a good response to e6 after all. We need to find something else. 

 
I've just done tons of analysis and typed it up and somehow erased it all. If he plays d6 I'll do it again later. But long story short, Rd2+ is OK response to d6, unless White plays perfectly, but if he does f5 might be better; I'm not sure.

OK, we're going to analyze the different variations to d6 Rd2+:

1. (white exchanges rooks after e7+):

d6 Rd2+ Ke1 e3 d7+ Rxd7 Rxd7 Kxd7 Because of the extra pawn on f7, this is a win for black. 

2. (white plays Ra3 after e7+ )

d6 Rd2+ Ke1 e3 d7+ Rxd7 Ra3 f5 This favors black because of a rook pin on the king. 

If Bxe3 Bxe3 Rxe3+ Re7, and black wins: Kf2 Rxe3 Kxe3 Ke7 Kf4 Ke6 etc. 

If white tries to escape the pin before playing Bxe3 (Kf1) then black can play f4, protecting the pawn on e3. At that point, black has a tremendous advantage with the two connected passed pawns, and we should find a way to win this. 

3. (white plays Ra8+ before Ra3 to defend the pin.)

This is a variation on 2, but it's easy to refute:

d6 Rd2+ Ke1 e3 d7+ Rxd7 Ra8+ Rd8 Ra3 and Kd7 allows for Re8 and the pin if white tries to grab the e3 pawn.

4. (white plays Kf1 rather than Ke1 and then Ra3)

So this is one of two variation after Rd2+ that gives white chances, and its the one that worries me and makes me think we might reconsider Rd2+. Two sub variations here: the first one without Ra8+

d6 Rd2+ Kf1 e3 d7+ Rxd7 Ra3 Now because of Kf1 there is no pin. And so:

f5 Bxe3+ Bxe3 Rxe3+ Re7

Obviously white is not going to trade rooks as that is a win for black. But what we need to figure out is, given this board, can we win from this position? (White to move, white with his King on f1, his rook on e3 and a pawn on b4; black with his king on e8, his rook on e7, a pawn on f5 and a pawn on d5. 

5. (white plays Kf1, then Ra8+ before Ra3)

This is the other variation that bothers me, and it's probably the most correct for white IF white plays d6: it escapes the pin and forces at LEAST a draw if we trade bishops:

d6 Rd2+ Kf1 e3 d7 Rxd7 Ra8+ Rd8 Ra3 f5 Bxe3

Now we can't play Bxe3 because Rxe3+ and Re5 wins one of our two remaining pawns. The question then becomes, is THIS position winnable for black? (black to move, black's King on e8, his rook on d8, his bishop on g5, his pawns on f5 and b5; white's King on f8, his bishop on e3, his rook on a3, his pawn on b4).

On the face of it, it doesn't look like black can win this. White's pieces are better placed to force a draw here. But keep in mind that to get to this position, white has to play PERFECTLY finding every move, particularly Kf1 after Rd2+ and Ra8+ after Rxd7 before Ra3. These are not easy moves to find unless you're either a grandmaster or you're spending hours looking at this board (like I just have.) 

So the question becomes- is this a winnable position for us? And even if it's not, should we take a chance anyhow on Rd2+ figuring that Kaspy won't find this sequence? That's what we need to decide before playing Rd2+ in response to d6. 

 
Whew! That was pretty exhausting. Later if he hasn't made a move I'll look at whether or not we can play f5 as a response to d6, instead of Rd2+

No, I'm saying HE could play d6 instead of Ra8+. Ra8+ seems automatic, but d6 may actually be better for white if he plays it perfectly. After Ra8+ Bd8 then what? 

If d6, f5

If Rb8 or Ra5, Rxd5, and we'll take that trade. 

Ra8 looks advantageous for us, though in truth I haven't looked at is as deeply as d6, because d6 if played perfectly can, I believe, force a draw for white (see my last post.)

This all looks good.  Nice to have fewer pieces on the board so I can actually follow the game in my head now :thumbup:  

 
pretty sure he is going to move that pawn down unless he wants a draw.   A f upped move now by either side could spell doom, but I really only see White with draw possibilities.   Black has winning possibilities.  IMO.

Nice job guys.

I'm not fully sold on this. I want to look at it later. White has some drawing chances here.

D6...f5

Rg7 probably...bf6

Not sure where he now puts his rook, but he moves it (rh7?)...f4... If he lets us get that pawn to f3, it's over. And he can't really stop it without just swapping stuff to our advantage.

D6...f5

Ra8+...kf7

Ra7+...ke6

Rg7 probably...then see above

 
Kaspy moves Ra8+. So you guys were right after all. So much for all my d6 analysis. 

OK we're all agreed long since that if he played this Bd8 was the move. After that we need to do some more analyzing. But I'm going to go ahead and play Bd8.

Agree.

His next move will require some thought.

I suspect it will be bb6. Rxd5 should be the response. No need  to really discuss.

Bf2 is possible, Rxd5 may be best there, as well, but we need to look deeper.

If D6, then i think we start the advance of our F pawn, but again we need to look deeper.

So what are white's choices? d6 seems like the most obvious move. My initial response was f5. But this loses us the b pawn. There is no way to protect it. 

d6 f5 Rb8 f4 Rxb5 f3+ And white has Kf2, Ke1, or Kf1 

1. Kf2 Bh4+ Kg1 e3 and then I think white has to take it, losing his bishop or the game is over. After that we only have one pawn left on f3, but if we can find a way to protect it with the bishop we win. 

2. Ke1 Bh4+ Kf1 e3 same result. 

3. Kf1 e3 same result. 

This looks great for us. So much so that I'm not sure that after f4 white can afford to take his rook out of play by capturing our b pawn, which makes Rb8 a wasted move. But what other move for white then after d6 f5? I can't see one.

Unless he plays d6 I'm inclined to agree with you and do grab the d pawn. I don't know what Bb6 would serve him. 

 
I think it's all about to hit the fan.

Bb6...rxd5

Rb8...ke7(we gotta get our king up supporting).

Bxd8...rxd8

Rxb5...ke6

Ke3...rd5

Rd7...f5

Kf4...now what? I am bad at this part.

 
One thing: in my above variation in which he captures the b pawn f2 might look tempting to play instead of e3 but there's a trap which leads to a draw: 

d6 f5 Rb8 f4 Rxb5 f3+ Kf2 Bh4+ Kg1 Rd1+ Kh2 f2 Bxf2 Bxf2 Re5+ and Rxe4

Keep in mind that for white can sacrifice his bishop and both his pawns in exchange for all our pawns- if he gets our pawns off the board, but still has his rook on the board, it's a draw. His bishop is expendable and we have to remember that he will look for a way to sacrifice it if he can get pawns in exchange.

If that's the scenario, after Ke7 he might play Bc5+ and he gets the b pawn without taking the bishops off the board. 

But In wondering if he's willing to give up his d pawn so easily. I still think he'll play d6 and Rb8. Guess we'll find out. 

 
Pretty sure he will move Bb6 to double the attack on our B.  But the automatic answer is Rxd5 as wilk said, no discussion needed.  So maybe he won't bother. 

In response to d6 we may want to think about Kd7.  Worth a look at least?  Both blocks and threatens the d-pawn and unpins our B.  Doing something else (such as f5) and letting the d-pawn advance to the seventh rank (after an Ra7 move) would pinch us uncomfortably.  I'm sure Kaspy likes the fact that its queening square is dark.  Of course he can play Ra7+ after Kd7, but our B would be free to move after Kd7 undoes the current pin.  Dunno.  Maybe merits some discussion.
