Soller-Zilbermints Gambit

After the dubious 2...f6 3. fxe5, Black plays 3...Nc6 rather than 3...fxe5 at once. The knight guards e5, so the Qh5+ tactics that punish the immediate recapture no longer work. The most common reply, 4. exf6, lets Black regain material with the developing 4...Nxf6, while 4. Nf3 allows 4...fxe5. The critical try is 4. Bb5, aiming to trade off the knight defending e5, and engines give White a slight edge.
