You may search the games on this site for all containing a player name or ECO opening code [in brackets]. Searches on specific opening moves (like: 1e4 e5 2. Nf3) seem to be less accurate with this FrontPage search engine.
Individual game files are named indexg#.htm where # is a number. Files named indexb.htm are lists of games from a tournament or round and you may select games on them too.
Press the Start or << button in the left pane before leaving individual games named indexg#.htm. Otherwise, the pieces will get messed up on the board and you'll need to close and re-open the window.
If this search engine appears to not be working, please email admin@ochess.org. Thanks.
