[ETM Switch Signal - Overview]
The ETM Switch Signal is
used when following suit to a suit declarer has played first, from hand or
dummy. It is similar to the
‘Reverse Smith’, though can be used against suit or notrump contracts, and
includes the trump suit. It is
used in combination with upside-down carding.
[ETM Switch Signal - Details]
Three Cases:
1) When following to opponents suit where count is
not important – use Switch signal
High not including
useful honor = switch recommended - shows a concentration of values in a suit.
Low = neutral.
If High first, next spot
card is suit preference if possible.
If Low first, next card
is Highest Spot Card Left to ask for suit led, up-the-line to continue to be
neutral.
2) In count situations:
From even play low, then
next card play high if like suit led, otherwise up-the-line.
From odd play high, then
next card to indicate best suit preference.
3) In situations where count or switch signal is
uncertain:
If an even number play
low, then either next lowest to remain neutral or high to encourage suit led.
If an odd number and
want a switch, play highest, then show suit preference.
If an odd number but do
not want a switch, play middle then on next card play lower if count still
important, and higher if count was not important.
