At Historicon I was in Bruce's game of the Battle of Lobositz 1756, playtesting the Lace Warfare rules. I was one of two cavalry commanders on the Austrian left, facing Prussian cavalry. Following are some postgame comments. Thanks to Bruce for running the game.

Off Board: One of my defeated cavalry units had a retreat which would have taken it off the side edge of the table, after a melee. The unit was ruled lost, which seemed acceptable, but a further question arose: What about the victorious and pursuing Prussian unit? I believe Bruce ruled that the unit spent a turn reforming at the edge. This also seemed acceptable to me for the SYW. However, if you have no specific rule on this (I did not see it in the full set), you might want to put one it.

Cavalry Fire: As I recall, the summary sheet had a line for carbines. The cavalry next to me actually had a possible shot. Due to a bad die roll, a Prussian cavalry unit's charge fell just short of a neighboring Austrian unit. I believe Bruce ruled no cavalry fire, at least for playtest purposes. My suggestion is that perhaps you ought to adopt this as a general rule(it is not already in the full set) for SYW cavalry, on the theory that any pistols, etc., are taken care of in the charge rules. In this instance, the Austrians did not countercharge as they had been standing still and had not been given advance orders. However, if the full set allows dragoons to dismount (none of the Austrian or Prussian cavalry commanders tried it), then perhaps carbines could be limited to dismounted troops.

Cavalry melees: In the cavalry melees in the playtest game, one side gained an advantage on the first turn of the melee, with victory/disaster in the second turn. I was expecting this from other SAGA rules. It seemed reasonable for the SYW. Another player indicated to me that he was more used to other SYW rules where a charge, rout, and exploit occurred in one turn.
