Truscott is normally used as a defence to Precision 1§ openers, or similar. However, with partnership agreement, Truscott can (and probably should) be used over any strong artificial opener, including Acol 2§, Benj 2¨ etc. although you would need to be rather stronger to overcall an Acol 2§ style opener.
The only rules are that the opponents opening bid must be strong (16+) and artificial (conveys no information about distribution). The rest of this discussion assumes the opponents open Precision 1§.
Truscott is used immediately over the opening bid, or after a strong opener on your left, pass from partner, and an artificial negative response (1¨ in Precision) on your right.
As soon as either opponent shows a genuine suit, or bids No Trumps, Truscott is off the menu.
Normal defensive methods, like takeout doubles, Michaels etc. just dont work when the
opposition havent shown any suits. For example, what does
Truscott allows you to show any single or two suited combination with a single bid. The ability to show two specific suits in a single bid greatly increases the chances of finding a fit. This means you can afford to compete with slightly weaker hands without compromising safety.
Truscott is purely defensive. The objectives are to prevent the opposition from finding their best final contract and/or to suggest a safe sacrifice for our side.
All Truscott bids show weak overcall strength, around 8 losers. Truscott does not provide any mechanism to show a strong hand. There are ways to overcome this. Crowhurst suggests a strong hand should pass initially and then bid on the second round. However, in around 20 years of playing Truscott I have never yet felt the need for a strength showing bid over 1§. If one opponent has 16+, that only leaves 24, at most, for our side. The chances of a game our way must be slim.
Truscott provides bids for all two-suited and single suited hands. There is no bid to show
a three suited hand. With

Truscott two suited overcalls show at least a 5/4 distribution. There are just six possible combinations of two suits. If we assume the order of the suits to be circular, in four out of the six cases the suits will be touching. The figure on the right shows the only two possible combinations of non touching suits: |

Truscott utilises all the available non-jump bids to show two suited hands. Touching suits
are shown by bidding the lower ranking suit (with ª and §, ª is
the lower ranking). For example,
With non touching suits including the suit just bid on your right, double. With non
touching suits which dont include the suit bid on your right, bid NT (you may like to think
of the NT bid as showing the suits either side of the suit just bid on your right).
A single suited hand is shown with a jump overcall. You should normally have a 6 card suit. Note that the jump overcall shows neither more nor less strength than the simple overcall. It just shows a different hand shape.
With a 7 card suit you can do a normal pre-emptive overcall by jumping to the three level. As noted earlier, it is wasteful to reserve jump overcalls to show strength over a 16+ point hand. No matter what strength your jump overcalls would be over a natural opener, over a Precision 1§ a jump overcall should always be treated as weak.
Responses to partners Truscott are completely natural. The 1NT and double are clearly forcing, but all other Truscott suit bids can be passed. The normal response is to raise partners suit, or whichever suit you prefer if partner showed two suits, to the maximum possible level. Partners suit bid can be passed if you think we are already as high as we dare be (and you dont have a preference for his other suit).
You should take the Truscott bidder for 8 losers but it might even be worth stretching by a loser, with a good fit, to try to disrupt the opponents.
Note that it is highly unlikely partner has anything useful outside of the suit(s) he has specifically shown. You bid any other suit at your peril. If you end up going off because partner has a void then its your fault!
