Playing a blitz game, I reached the below position:

[Title "White to move"]
[fen "1r3rk1/1q1nbpp1/p1n1p2p/P1p1P2P/2Pp1BN1/5BP1/1P2QP2/R3R1K1 w - - 0 1"]

At this point both players had less then a minute, so I played b4. My idea was to slow down Black counterplay on the queenside, in order to get time for my attack ( ...cxb4 is the only move ). My opponent blundered and lost on time.

I do not have an engine available at the moment, hence this post. I want to know the following:

Does White have winning advantage in the above position, or Black, or is it a draw ?

I seek concrete lines and moves. You can use engines if you want.


From the original position, Stockfish doesn't see a whole lot going on. I don't think this means the game is drawn, but simply that there's no knock-out. Stockfish scores the position as slightly in White's favor. This "ideal" continuation doesn't seem suitable for a blitz game; there's too much moving for the time allowed.

I then ran the b4 move which yields a small advantage to Black. But holy smokes look at the "final" position. Black has two deadly outside connected passed pawns while While surely has a devastating King attack in there somewhere. I'll let this grind while I go to work...

ALNS, if you have specific variations, let me know and I'll run them.

EDIT - Here's the analysis of 1.b4 after something like 10 hours. This is coming down to a draw. I don't think Black can convert this.

  • Thanks, that is exactly what I was looking for: a comprehensive analysis. I have upvoted, but will wait for your analysis of b4 to end. I think that currently, your analysis offers winning chances for Black, so maybe b4 was a mistake... I guess in the strongest continuation Black is slightly better, or it is completely equal. I am surprised to be honest, because I had so many pieces at the kingside that I thought I should break through somehow... After b4 I was Be4 + Bb1 + Qe4, I wonder if you can somehow analyse that plan? Thanks anyway... – AlwaysLearningNewStuff Apr 18 '16 at 18:45

This is what I like to use Lichess for


It's not nearly as powerful as stockfish or the likes but you can get a general idea whether you had particularly strong tactics available.

According to the analysis it sees an opportunity for a draw through perpetuals by sacrificing the bishop on H6 but no particular advantages to either side to play for. It favors Qd4 which does centralize the queen and puts some pressure on the knight on c6 but overal it's very even.

  • I saw nothing on the link you provided. Do I have to be registered member in order to see the analysis? – AlwaysLearningNewStuff Apr 18 '16 at 10:10
  • I edited my link, otherwise use the analysis option(under tools) and paste the position in the FEN string. – bucketman Apr 18 '16 at 10:40

Not really.
You would need to play it out to the end to be sure.

And even then there would be questions like what if at move 77 I did this move instead of that move.

Even engines would not be definitive. But if you played the position out a thousand times between two engines you could get a statistical answer but still not likely to be definitive like the OP implied.

That said, my intuition says white could win and should at least draw. OTB especially blitz ,I would be trying for that mate and expecting a perpetual at worse.

I would play Q-Q2 (qd2 for the kiddies:) and look at the bishop taking the king rook pawn followed by Be4. Black might play P-KB4 [Pf4] to hold on but his position would not be as good and white could ultimately win.
