There are many examples of getting to the same position by different sequences, but the first game in this collection is
interesting because 1... e5 is a rare response to 1. Nf3 ...
but 1... e5 is the second most common response to 1. e4 and the most common response to response to 1. e4 e5 is not surprisingly 2. Nf3 (in fact Nf3 is a common second move for white regardless of white's first move) the most common response to 1.e4 c5 is also 2. Nf3. I am not sure why anyone would respond to 1. Nf3 with 1.. e5 since it leads to the obvious next move 2. Nxe5 Whether this sacrifice makes any sense is difficult to discern because it is so rare.
