"Armadillo" - Transfer 2/1 Responses

Opener starts with 1M, and we modify Responder's bids between 2♣ and 2M for bidding advantage. I also make suggestions for bids above 2M but those are not critical to the system. And then recommended higher level bids:

Continuations After 2♣ Game Force

We have jammed three types of hands (clubs, diamonds, balanced) into this sequence, and you might think it becomes awkward, but the good news is that not having to use space to show 3 card raises is enough to usually put us on an even keel, unless things are misfitty, in which case we're usually ending up in NT anyway.

Opener typically continues with shape

There is some bidding space left over here; 3OM, 3NT and 4 level bids. I do not currently have good suggestions.

After 1M-2♣-2♦

Opener has denied any special shape so Responder can now express their hand. Note that neither 2♥ nor 2♠ are needed as neither 8 card fit is possible. Later on, Responder may bid M naturally to try to land in a 7 card fit, but for this turn, we are trying to confirm a minor suit fit at 3m. again there are various bids unusued which we can define later. Like perhaps 3M shows a splinter with 55 minors.

After 1♠-2♦, Transfer to Hearts

Opener bids at the two level to show a minimum, and anything else is a game force. So, in particular: If Responder makes any call over Opener's minimum showing 2 level bid, that is natural and creates a game force.

After Invitational+ Major Raises

That is, after 1♥-2♦ALERT, 1♠-2♥ALERT, (and 1M-2NT). Here we use: So note that in particular we do not show a minimal accept by jumping to 4M in case Responder has slam interest of their own. 3M can be a control bid in trumps(?)
