1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 e5 {This move cannot be found at the Chess Informant Encyclopedia. Under section B54 only 4...e6; 4...c6 and of course 4...f6 are considered. After 4...f6 5.c3 e5 is a well known variation, however I could find nearly 30 games with 4...e5 directly in my database.} 5. Bb5+ {Instead all  moves except 5.f5 have been played without success. The bishop check is typical and best, intending to take immediate control of the white squares.} Nd7 (5...
