DrMAL: Thanx <FSR> for pointing out game in H Charlick vs W Tullidge, 1887 I agree with statement above, idea of 2.e5 is underrated move, at least for club play, one could go wrong as Tarrasch (surprisingly!) did immediately here with 2...f6 as noted above 2...d5 transposes to Advance French and is most common reply.
With 2...c5 game transposes to Charlick gambit 1.e4 c5 2.e5 with reply 2...f6?! instead of "normal" move 2...d5 that Charlick made unique via 3.exd6 (Opening Explorer). Here is eval after 3.d4! probably best.

With 3...c5 it is still weird opening resembling French (f6 instead of d5). After 4.Bd3 strong move (4.dxc5 has also been played I do not think this is as strong) Tarrasch's 4...f5?! is (suprisingly poor!) attempt to make position look like Dutch but this would already be a key tempo behind. 4.g4 was very interesting it sharpens game, but maybe 4.d5 was even better, here are evals before and after strong 4.g4 move.

Game was interesting double-edged battle with ups and downs. For example, 11...exf5?! tilted edge back to Pollock but he played 12.cxd4 instead of 12.Nb3 difficult to see big advantage this would gain. After 12...Be7?! however, Pollock played 13.Nf3! for big advantage anyway and then, with 13...Kd8? instead of 13...d5 it looked like beginning of end, but series of minor inaccuracies allowed Tarrasch to survive.
18...b6? was losing move, it weakened black K enough for end to follow even with inaccuracies. Tarrasch played poor game (for him) from outset but Pollock still gets credit for persistence and overall strong play, nice game for him!
