51 ( +1 | -1 ) 1.e4 c5 2. f4...I Believe this is the Macdonnell attack (old Grand Prix Attack).
Now, I've read 2 ...d5 is a good response but all the variations I've read are taking into account white playing 3.exd5. Then black is supposed to play 3...Nf6 with a good game. However, I was wondering, what if white simply pushes the e pawn on? 3. e5?
Could the sicillian player be sort of tricked into playing a french?
This has been bothering me lately as black as I hate playing the french. And after 3.e5.. ...e6 seems inevitable.
14 ( +1 | -1 ) 3. e5is a not particularly favorable variation of the Center Counter(?). It's like a French but the Black bishop is not committed to c8 yet. 3... Nh6 is the best move IMO, followed by 4... Bf5 or 4... Bg4 (intending 5... e6).
46 ( +1 | -1 ) black can also play d5 and has a good square on d4 for knight. This a paricularly unfavourable french for white, as black can develop his light coloured bishop where normally in the french he can't. No good player would ever play 2e5 in that position. Also many top players play e6 insted of d5. The idea of d5 is to prepare the sacrifice e6 where black then takes with his bishop and has good control over d4, and often f4 becomes weak.
