I’d play 3. d3 and make Black kick the N again. I don’t think this gambit is very, um, challenging to White. But he should be willing to use a different setup from the usual Reti, in return for the free pawn.
I knew the first move was that of a Reti (barring transpositions), but wondered if Black’s first gave the opening a new name like Pegaze Counter-gambit or if there was another name for it.
White starts as a Reti, of course, but I think Black’s play here is more properly referred to as the “Counter Reti Accelerated Polish”. I think there was also an acronym for that line but I can’t recall at the moment what it was.
Yes - it was actually (further) nicknamed the “sodium attack” - because of the commonality between its algebraic designation “Na3” and the symbol for sodium, “Na”.
Heh I don’t think I have heard of that, and usually the “middle name” was said in descriptive. I was in Wilmington and he came over for the Delaware Open that year. Is Bird’s Opening ever called the Fluorine Attack?
