Does playing with White without the e2 or d2 pawn make it even?

[Chessqueen]

I have tested several games to find out how great of an advantage it is by making the first move, and I have removed the e2 pawn or d2 pawn whereas Black play with all its 8 pawns. To my amazement by White making the first move even without the e2 pawn it managed to draw in 49% of the time. Here is an interesting game where I set Komodo Dragon to Level 2225 playing by itself

Hi.

Interesting.
I would have thought that a pawn is worth a lot more than moving first.

Of course a pawn, especially d or e, worth more than first move, 49% are draw, probably 51% are win for Black, furthermore imbalance would be much greater with stronger player. However, how many games are been played here?

I've run hundreds of games between top engines at full strength at various time controls with one White pawn removed. If it's a rook pawn, most of the games are drawn, Black winning most of the others. If it's f2 or g2, must of the games are lost by White. These results are to be expected, since there is major compsensation with rook pawn off, and none at all with f2 or g2 off. But with b2, c2, d2, or e2 removed, White usually draws nearly half the games, almost never wins a game, and loses the other half. It's not even particularly clear whether more time or threads helps White to draw or helps Black to win more. In all four cases, White has the first move plus a little extra mobility for the pawn, and although central pawns are more valuable, their removal gives more added mobility than c2 or b2, so all four cases are quite similar, White has maybe 0.3 pawn compensation, and being down 0.7 pawn is thought to be right at the win/draw line. If I had to bet, I would bet on Black to win rather than on White to draw, but all four positions are so near the loss/draw line that no one can tell whether they are lost or drawn with perfect play. Perhaps some of the four are drawn and others are lost. This means that all four of these positions are nearly ideal for Armageddon chess, in this case with White getting the draw odds. The only problem with using these positions for engine testing (with Armageddon rule) is that you can only play eight games before having to repeat the same pairing, and there are no opening books to provide variety, so you either have to generate them or just rely on MP for variety. This is very similar to the "No Black Short Castling" Armageddon chess promoted by myself and S. Pohl a while ago, which is also right on the win/draw line. Whether Black forfeiting short castling or White removing a pawn is more like normal chess is a subjective matter, hard to call.

I only played 100 games, sorry my calculation was wrong it was only 47% draw, but White loses most of the other games, but still moving first is a big advantage, and besides that TCEC still pick Openings that are favorable for White which makes it even more unfair. I was fooling around and decided to pit Stockfish versus Komodo Dragon 2.6.1 where I decided to set the Elo limit to Komodo to 2780 just like GM Magnus Carlsen, and removed the e2 pawn from Stockfish playing with the White pieces to see if GM Carlsen has a chance of beating Stockfish, but I believe that Carlsen probably need at least twice that amount of time control T/C of game in 180/5 Minutes

Interesting most of the games are drawn with the Rook pawn Odds, so far 10 games with 10 draws

The Main question to you Mr. Larry Kaufman is, do you believe that Komodo Dragon can beat Carlsen at T/C of 90 Minutes plus 10 seconds Bonus with the f2 pawn Odds? I will first test Stockfish at full strength vs Komodo Dragon with a limit Elo set to 2780 simulating the World Chess Champion Carlsen, to see what happen, can you predict the winner ?
