2nd Negros Closed Invitational Chess Championship 2012 Rd.9 NM Acaling vs. CM Montoyo Sicilian Defense (B27) I would rather not mention in detail the controversy that happened before and during the game since everything turned out to be alright after it. 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d5! Honestly, this is the first time I encountered this move, which means my opening reference is very old, but probably not yet obsolete :) There are many moves in this position 5..Nc6, 5..Qb6, 5..Qc7, 5..Bc5 but perhaps the most popular continuation here is 5..Bb4 while 5..d6 will transpose to Scheveningen type of position. A few days after the game I found out that the "stem game" according to a DB that I consulted (which contains only 2.5M games) was first played in 1996. The whole concept of the set-up -Nf6, -e6, and -d5 is nothing new, the idea was just lifted from other Sicilian
