Seizoensopening 2018-19

De seizoensopening had dit jaar wat anarchistische trekjes omdat ongeveer de helft van de aanwezigen de voorkeur aan het gewende zaterdagsvluggerrondje gaven in plaats van de geplande onderlinge teamwedstrijden. Niets mis mee, er waren genoeg leden en gasten aanwezig voor beide activiteiten. Een gezellige schaakmiddag met zo'n 30 deelnemers als smaakmaker voor het aanstaande seizoen.

Because if you will move the pawns then for black it will become moreeasy to attack them.  B: The white king has to become more active, and so ithas to go to the centre.  C:The white knight has to stay close to the whiteking, because it is not a wide range piece, like the bishop.} g5 $1 {I totally didn't consindered this move.} 29.
