Petrov defence

I have a question about the Petrov defense, please. Can it transpose to another opening? Thank you.

Another one it often transpose to is the Exchange French.

Same position arises after

1.e4 e6 2.d4 d5 3.exd5 exd5 4.Nf3 Nf6

AND

1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.d3 (instead of 5.d4 or 5.Nc3) 5...Nf6 6.d4 d5 (All other Black 6th moves are weaker.)

In fact, at the 2014 US Open in Orlando, all 5 of my games as Black started 1.e4 e5 2.Nf3 Nf6. NONE wound up a Petroff!

Round 1 - Exchange French vs 1300 - Win

Round 3 - Four Knights vs 1700 - Win

Round 5 - Exchange French vs 2150 - Win

Round 7 - Four Knights vs 2250 - Win

Round 9 - Four Knights vs 2300 - Draw

That is to go with a loss to a 2100 in Round 2, a win in Round 4 against I think an 1850, and draws rounds 6 and 8 against 2300 players, all 4 of those I had White and played 1.b4.

Scored 6.5/9 and finished in a 2 way tie for 1st in class A (was 1993 at the time). That event is where I have won the most money ever in a single event - just short of $1500.

thank you for the responses. I was also looking at ways that white can avoid the Petrov .

1) Kings Gambit 2) f4

2) The Vienna game 2) Nc3

3) The Vienna Gambit with f4

4) The Bishops Opening 2) Bc4

Are there any others? thanks

i think d4,0-0,and Nc3 are all their own lines
