Is this a win?

Post by Karol Majewski »

Guys, I have a position after moves: 1. e4 e5 2. Nf3 d5 3. exd5 e4 4. Qe2 Qe7 5. Nd4 Nf6 6. Nc3 a6

rnb1kb1r/1pp1qppp/p4n2/3P4/3Np3/2N5/PPPPQPPP/R1B1KB1R w KQkq - 0 7

Of course it's much better for White, but is it already winning? Basically, there are three sensible options for White now: 7.g3, 7.h3 and 7.d3. I'm clicking around these moves with the latest Stockfish and I'm getting nowhere. The evaluation always goes up to +1.90 but than it cannot make any progress. Maybe someone with supercomputer can take a look at this and find the winning path here?

Thx for your input, Spliffjiffer. Could you post some of these games?

I'm still trying to squeeze a winning adventage in this position and it seems to me that 7.g3 is the way to go, although I cannot reach evals above +2.00.

SF-abrok, self-play (aka monte-carlo), for first couple moves I got D up to 64, next 50+, Hash=8 Gb
White win, but probably due to black blunder. There is high probability to move back and forward and find black move with fail-low and play another black move which can hold draw.

rnb1kb1r/1pp1qppp/p4n2/3P4/3Np3/2N5/PPPPQPPP/R1B1KB1R w KQkq - 0 7

Of course it's much better for White, but is it already winning? Basically, there are three sensible options for White now: 7.g3, 7.h3 and 7.d3. I'm clicking around these moves with the latest Stockfish and I'm getting nowhere. The evaluation always goes up to +1.90 but than it cannot make any progress. Maybe someone with supercomputer can take a look at this and find the winning path here?
7.d3 was by far the most often played move at chessbase online database with this position, here are the 8 games to be found there with this first one for White, so after 1. e4 e5 2. Nf3 d5 3. exd5 e4 4. Qe2 Qe7 5. Nd4 Nf6 6. Nc3 a6 7.d3

5-2-1 as WDL- result of course isn't of any statistical meaning with 8 games only, yet I guess with lots of eng-eng-games it still would depend on engines and hardware- time much also. You could take it as a draw- killer- opening for rating lists, couldn't you regards

Re: Is this a win?

Post by Karol Majewski »

After weeks of clicking around I came to the following conclusion: All three moves are winning: 7.g3, 7.h3 and 7.d3. The cleanest move (the best) is 7.d3 cause it wins faster than the other two moves (faster = in less number of moves). Thanks for your input.
