Gunderam Gambit

The Gunderam Gambit arises from the triangle move order of the Semi-Slav. After 4. e4 dxe4, White skips the natural recapture 5. Nxe4 and plays 5. f3, leaving the pawn in Black's hands in return for rapid development and an open f-file. Most players accept with 5...exf3, while 5...Nf6 is the main alternative and gives Black better practical results. The engine slightly favors Black, though White scores well in the few games played.
