Blocking the invaders (in or out)?
Another of my 'error-prone' games (both of us made errors), but is still a good example of how to lock-out/put-in-prison/block-out invaders.
It is also a good example of why we should not play too many pawn-moves at the cost of development - in the opening.
In this case, my opponent's queen and a bishop barged in, leaving their King at the mercy of my better-developed forces.
Hope you enjoy the game. Comments and criticism welcome, as always.
[Note: The humour in my comments is only to add a bit of interest into the narration. Not in any way jesting about my opponent - who is a strong player and probably had an off-day that day.].
