Why not try our databases?

This is correct. Rebel8 was beating MCP4/5 with 6-0 in this opening. Then MCP
played 8.- c4 9.Be2 0-0 10.h4 f5 11.Qg3 Qa5 12.Bd2 Qa4 13.Bd1. When MCP6 arrived
we saw the topic line for the first time. Except for a difference from move 33.
But MCP6 won two games against Rebel8 in 47 moves. All 8 games are in our
databases.

He asked Marty if he found them. :-)
