Connector from T spawn smoke
Jumpthrow used for this smoke.
You should be able to see the little black hole on the ground, stand on it (center your crosshair), then align at the middle of the more brown circle from the wood, and align with the top black circle from the right building.
My bind for the bigger crosshair is:
bind "c" "toggle cl_crosshairsize 1000 3" (where 3 is my usual crosshair size).
