OpenChess

I played a 2 game match with the Morra Gambit, starting after 3... dxc3 - Houdini white in one game and black in the next. I couldn't help but notice that both Houdini and Komodo like to deploy the king bishop on e2 instead of the usual Bc4. I'm not a theoretician so I can't say much about that, but I don't see that in the books. Both games ended in draws, which used to be my experience when playing it as white, it was always good for draw!

does not take into account the long-term benefits of the pawn sacrifice in the
Morra such as active piece play and attacking opportunities. Also someone
using a computer will think he is doing well when suddenly the silicon monster

The non-standard field cce is the calculated ce as a function of actual game play outcomes. white_wins, black_wins, and draws are the outcomes from my high quality game database.
The curly braced numbers next to the predicted moves are the number of times the preceding move was actually played in a game.

Harvey, there's also EL-SHADDAI-Werty1000, 0-1, 04.11.2011, 3m blitz game on Playchess.

That is indeed an interesting game! I used to play the morra gambit myself when I was a tournament player and I rarely lost with this opening although I often had a difficult time converting.

Don

P.S. Komodo seems to like your 11. Nxb5 move, never once looking at Bxb5. I think most humans would automatically play the bishop move to get the pin. I do know what other computers would play here though.

correspondence games. This is because most players will use a computer
although they tend to say it is only to avoid blunders. However, I suspect a
few who have limited time to study will also use it in the opening.
Consequently, Black will assume he is doing well here because the computer
does not take into account the long-term benefits of the pawn sacrifice in the
Morra such as active piece play and attacking opportunities. Also someone
using a computer will think he is doing well when suddenly the silicon monster
will realise what is going on by abruptly changing the assessment.} Bg4 {It

That is indeed an interesting game! I used to play the morra gambit myself when I was a tournament player and I rarely lost with this opening although I often had a difficult time converting.
